I am experiencing my WIFI Calling Preferences always being forced to “cellular preferred”, as are others.   I live in an area with poor T-mobile mobile data signal and this recent behavior makes my phone unable to make and receive calls and text messages.   I believe the problem only started happening after the next to last T-Mobile software update.  Everything was fine for my first 5 months of ownership.  A Google search shows posts of other users experiencing the same issue, but no options other than a tedious workaround of manually switching the phone to Airplane mode and changing the WIFI calling preferences back to “WIFI preferred”.  I have to do this kind of process each time I enter and leave my home, and sometimes have to reboot my phone as well.   The times I’ve forgotten, I’ve missed package deliveries and went to a doctor appointment when the doctor had left a message that he was out sick.  This appears to be a carrier specific issue as far as I can see.   I even tried replacing my rock solid Netgear R6400 router with an ASUS AX3000 router with no resulting changes.   I’m in a small apartment only 10 feet from the router, with a very strong WIFI signal.  I have two Samsung Galaxy S20 phones (March 2020) which both exhibit the exact same behavior.   I spoke with T-Mobile Tech support which appeared to be clueless about this issue other than to send me two new S20 phones under warranty to my T-Mobile store.   I do not have high confidence in this approach but will try the new phones and report back. 

Does anyone know anything more?   I am not aware of T-Mobile publicly acknowledging this issue.

AGREED!!! Not Tmobiles business weather we have that setting on or off. Why have the setting if we can't use it. Might as well be grayed out in the menu.

I have Note 10, Note 10+ and Note 20 Ultra5G. They all have this issue. I updated the phones and did factory reset also but I still have this issue.

I rely on Wifi calling at home and with this feature gone the phones are useless.

When will this be resolved or else it might be time to such back to iOS.

I am working with T-Mobile corporate to try to resolve/mitigate my issues. Like most here, I have the Wi-Fi optimization issue, switching from Wi-Fi to cellular, even though I am just feet away from a very good ASUS router. My cellular signal strength varies from 2-3 in the best location to 1 or none in other areas. I want to be able to take my phone anywhere in my house and not lose a call. This originally worked great with Ethernet connected CellSpot routers, but died after a software update. Many updates later and still doesn’t work reliably. I since upgraded to ASUS RT-AC86U routers, hoping to have better connectivity and reducing the impact of leaving T-Mobile. Didn’t help my Wi-Fi optimization problem, but my kids notice the faster speed when they visit.

Call support was no help. Every suggestion failed.

I have an additional issue that I haven’t seen explicitly addressed. I frequently have incoming calls routed directly to voicemail after what seems to be a futile attempt by the T-Mobile network to locate my phone. It takes about 30 seconds for this to happen. The voicemail notification may be quick, or it may take a while to appear. This can happen when in cellular or Wi-Fi mode. It might be after a phone directed optimization takes place, but no way to know for certain.

Being old, I don’t game or watch videos (other than news or weather), so my phone is primarily for communication. Since it often fails to communicate, I consider it defective and subject to replacement under my T-Mobile warranty. The problem is getting a replacement phone that doesn’t have the problem.

To be certain to remedy this issue on T-Mobile, that means an iPhone.

Since this problem seems to be exclusive to T-Mobile, it is actually cheaper for me to switch to Spectrum Mobile using the $14 per Gig plan. 

If T-Mobile doesn’t have a solution soon, I may have to switch.

I set my Galaxy S9 to airplane mode, then turned on Wi-Fi and Wi-Fi calling last night. It should never switch to cellular and always be active on the internet. This afternoon, I called my cell from my home phone and got the message ‘This phone is not accepting calls, try again later’. Five minutes later I tried again and my phone rang almost immediately. Five minutes later I tried again and after about 30 seconds I was sent to my voicemail. This has to be a phone and T-Mobile Wi-Fi calling network issue.

There is no workaround for this problem, and T-Mobile and Samsung seem unable to fix it. If you need to use Wi-Fi calling when you have poor cellular service, expect to miss a lot of calls.

The only fix on T-Mobile is to switch from a Samsung phone to another cellular phone company product. This probably means a phone upgrade at regular price to fix a problem caused by T-Mobile and Samsung. 

If you like Samsung phones, like I do, the solution is to switch to another cellular provider. I have Spectrum Mobile in my area and their price for a senior citizen not using much high speed data is much cheaper than my T-Mobile plan. The problem is it uses the Verizon network and my S9 is not supported. I will have to get a new phone, but even then if I use less than 1 Gig per month the Spectrum plan cost will still be less than my current T-Mobile plan, even paying for a new phone.

The secondary issue I have is with customer support. My problem was forwarded to Technical Support and I was told to expect a callback. A week later, after no callback, I called in again and eventually was connected to Technical Support. They had me try a few things, but nothing corrected the problem.

I am in contact (I thought) with corporate customer support, but after first contact they seem to be ignoring me as well.

I get the feeling they want customers with problems they can’t fix to go away.

They will soon get their wish.

This will be my last post on the Wi-Fi preferences changed issue. Once I switch carriers, I will have no reason to say anything else.

I have three issues

  1. My Calling preference for Wi-Fi calling being changed to Cellular against my wishes. No, my preference didn't change, it was changed without my permission.
  2. While using Wi-Fi calling, some incoming calls are missed. This has no relation to #1, since it happens when I am in Airplane mode with Wi-Fi and Wi-Fi calling turned on. My preference for Wi-Fi calling isn't changed.
  3. T-Mobile customer support does not have the practices and procedures to support their customers with this issue. T-Mobile and Samsung seem to not have the competence or desire to fix this issue.

I switched to T-Mobile specifically to get Wi-Fi calling. We traveled to Sedona on vacation and stayed in a resort in the Oak Creek Canyon wilderness area. The resort offered Wi-Fi, but there is no cellular service in this area. To use my cell phone, I would need Wi-Fi calling. My T-Mobile phone worked without problems on this trip. In future trips we have stayed in remote accommodations not offing cellular service but with Wi-Fi. My Wi-Fi calling has worked flawlessly.

But with what I have heard called as the Pie update, Wi-Fi calling has been an issue. For a couple of years T-Mobile customers needing Wi-Fi calling due to no or inconsistent cellular service, Wi-Fi calling has been unreliable. No suggested settings, no workarounds, no updates fix or mitigate the problem.

More disappointing is the incompetence I have seen in customer support. T-Mobile practices and procedures, as well as the technology used to support contacting the customer have exacerbated the issue. Customer support does not get back to the customer when a response is promised. Customer support seems to not understand the serious of the issue to the customer.

I have used and worked in IBM customer support. Their system is oriented in getting solutions and keeping the customer informed of the progress of the solution. The support system keeps a knowledge base of known problems and solutions, and reminds customer support when a response is due to the customer. The T-Mobile system seems to offer none of these important features.

I was employed at IBM when Lou Gertsner was hired to do its turn-around. He told us anyone dealing directly with a customer was in sales. I was skeptical, but came to understand what he was saying. It is especially true today when most of our interaction with companies is through the internet. Unless we visit a T-Mobile store, our dealings are with customer support. They don't sell us things, but they can definitely make us ex-customers. Poor customer support and inability to fix or understand the customer's problem makes the customer to look for solutions elsewhere.

I was at such frustration with phone customer support I wrote a letter to corporate customer support and heard back from a corporate rep. I was in negotiations for a solution when the rep seems to have disappeared. No rep, no solution. Only silence.

Although my cellular service is still weak, and very weak or nonexistent in parts of my house, I have turned off Wi-Fi calling for now. I spend most of my time at home in my man cave, and the T-Mobile signal is strongest (usually 1-2 bars) in this room. I leave Wi-Fi on for other functions to work in weak signal areas. This works at home, but I will need reliable Wi-Fi calling on vacations, so I need to find a cellular service that supports reliable Wi-Fi calling.

I don't use 5G now, and probably won't need it for a while. I don't game or stream. But since it is available, I will get a 5G capable phone when I switch. What makes this decision sad is T-Mobile is poised to offer the best 5G C-Band service, as Sprint owned a good number of the C-Band frequencies.

I am looking at 3 Verizon network options

  • CREDO - good but not lowest price for my usage, but among the best customer support. Online only.
  • Spectrum Mobile - best pricing, but very new at the customer support business for cellular service. Does have a local office.
  • Verizon - Owns and controls the network. Not best pricing. As a previous customer, the support was good.

A year later, the problem persists! I am new to T-mobile. My galaxy S21 wiFi calling switches back from wifi-preferrerd to cellular-preferred after a few days. I think this happens when I leave the house and come back but it seems random.

T-mobile, this is more than annoying! I miss important calls when this happens because cell coverage is spotty in my house. Fix this!!

I am breaking my promise. I am making one more post as a T-Mobile customer.

I am leaving T-Mobile for CREDO Mobile. I do this with regret. When I joined T-Mobile it supplied voice reliability through Wi-Fi calling. As long as my Wi-Fi was working, my phone used Wi-Fi calling with no problems. If I had any problem, T-Mobile Customer Care came up with the solution.

This all changed with a software upgrade two years ago. Wi-Fi calling became unreliable, and my voice quality suffered. It kept getting worse. I started losing calls.

Over the past months I have put a lot of effort into trying to get T-Mobile to fix the problem. Calls to customer care did not provide a solution, and a promised callback from technical support never happened.

A letter to customer care at headquarters resulted in a call from a customer care rep, but my cell phone quality was so bad we had to switch to my land line, and then to emails. Still no solution, although I was offered a discount on a new iPhone.

I then searched for T-Mobile USA management and found Callie Feld, executive vice president and chief customer experience officer. I sent her a letter detailing my experiences and asked for help. I waited a week and a half, then sent her another letter yesterday saying the wait was over, I was switching to CREDO.

T-Mobile customer care is the main face of T-Mobile to its customers, and it is the face they see when they have problems. When customer care fails to provide the needed support, T-Mobile looks bad. With this issue T-Mobile looks incompetent.

T-Mobile should be able to query its problem database to determine how many customers have this issue, how long they have experienced this issue, and the models of the phone that are having this issue. Customer care should be sharing this data with product support. They should be saying ‘Albuquerque, we have a problem.’

So I will say it. Albuquerque, you have a problem.

@manotee well said. Ditto. 

I’m having the same issue, and I never get more than one or two bars at my house. The only thing that works is Airplane mode and turning the WiFI and WiFI calling back on. This is a terrible solution, but the only one that works.

Hi,

I am having same issue with T mobile (wifi calling preferred) so I do not have any signal in my phone and literally cant use for call or internet. I ported from ATT to T mobile and it seems like a scam. T mobile centre people do not have any idea about this issue or they pretend to be and call it unique problem and asked me to buy new phone. I recently bought phone and cant buy again just for this.

 

Please let me know if any solution you guys have for this issue

 

Thanks

Same issue for a long time.  I grabbed a screen shot the last time of the notification which says "WiFi calling preferences were auto updated..."  The key word there is auto.  I believe they periodically and automatically push down the change.  There has to be an advantage for them.

 

  I've called many times always having to go up 2 levels.  They deny it is happening nor that they have ever heard of it.  One time I talked to a tech that was quitting and he said his own phone does it and he couldn't get it resolved.

 

This needs to go to a class action law suit.  TMo has no right to change your phone settings.

 

I expect I will be leaving them as well.  What are our choices? I need a reliable phone.

I was using an S21+ originally on the Verizon network and ported to TM.  This problem did not happen on that device.  I purchased a T-Mobile S22 Ultra and I immediately started getting this problem.

I have 1 - 2 bars cellular and 2 excellent Wi-Fi routers with a super high signal strength.  So, there is no possibility that anything is actually being “optimized”.  ‘

I did call TM tech support.  They blamed Samsung.  It is very disconcerting that this problem has been going on for years!

I have no problem with the phone temporarily switching to cellular if the phone sees a problem with wi-fi.  However, I have a major problem with them resetting the wi-fi preferred option I deliberately set.  That makes zero sense.  Suddenly a 30 second issue with Wi-Fi strength becomes a permanent preference for cellular???? 

This is a huge problem because all my calls are going from crystal clear wi-fi to very broken cellular.

At the very least if they “optimize” to cellular they should re-optimize back to wi-fi when wi-fi is better. Instead, it just goes in one direction.

I’ve been fighting this a LONG time.  I don’t believe it to be a Samsung issue. They will tell you anything to get rid of you.  They DO know it is an issue for many.  Switching between WiFi calling and cell calling doesn't need to change the preferred method setting.  I’ve had inside sources tell me that it is TMo doing it.  They want you to use the cell system not WiFi which is why they keep pushing the change.  For those with good cell signal strength it doesn’t matter, which is why they make the change.  For those with poor cell service it is a huge problem.  TMo needs to understand and stay out of your settings!

I too have a new S22U.  I did not automatically transfer across everything, but took the time to install new.  I purposely limited and avoided everything TMo related.  It has yet to happen to me on this phone.  I do not do auto updates and nothing TMo ever gets updated.  I am in the process of doing a debloat.  I will root this phone if I have to.

I agree that it is likely some TMo bloat/firmware that is doing this since the VZW phone I was using didn’t have the problem.

Yes, I knew that they were likely just trying to get rid of me.  Since I’m retired I can take the time to go to Level 2/Manager support.  That is a task for this week now that I’ve done my research.

In the mean time I’m trying the Tasker hack that is supposed to automatically turn wi-fi preferred on if anything turns it off.  I don’t know yet if that is going to help, but it is worth a try. 

Samsung support said that this isn’t their problem since all wi-fi calling features are carrier specific.  I had to try.

I don’t know if there is a root for the S22 yet.  Even if there is I probably won’t do it yet since with a new model there is often a flurry of stock firmware updates for the first few months.  I’ve read that there is one coming.

Well, I was actually surprised recently.  My phone preferences automatically “optimized” briefly to “prefer wifi” rather than the other way around.  That was the first time I’ve seen that.  Either way, the phone/T-Mobile should never change a user preference.  It can/should change which way it chooses to make/receive a particular call, just not a preference.

I know this is an old issue, and I have also been seeking a solution for a LONG time, but I have cautious optimism that I may have discovered a solution. Samsung includes a “feature” called “Intelligent Wi-Fi” through its “Knox Ecosystem” that, apparently, attempts to adjust its phones to optimize data usage through the application of artificial intelligence to monitor user behavior over a period of time after which settings are automatically modified, including the prioritization of either wifi or cellular data for handling calls and/or texts. I recently noticed a notification on my handset informing me that it had automatically switched my wifi calling setting from wifi preferred to cellular preferred. For some reason, this prompted me to go to my actual wifi settings rather than my wifi calling settings, after which I tapped the 3-dots icon in the upper right corner and selected “Advanced” Wi-Fi settings. There I discovered a category called “Intelligent Wi-Fi” with a setting called “Switch to mobile data” turned ON, and that contained an explanation saying “Use mobile data whenever your Wi-Fi internet connection is slow or unstable.” A little research revealed this article on Samsung’s website: https://docs.samsungknox.com/admin/knox-platform-for-enterprise/kbas/kba-360034073174.htm, where I learned that Samsung had experienced problems in the past with users having their phones switched to cellular data against their wishes, causing them to update the software in the manner described in the article. This inspired me to turn the “Switch to mobile data” setting OFF, after which I have now gone several days without experiencing the dreaded automatic switching back to “Cellular preferred” on my Wi-Fi Calling feature. Not enough time has gone by for me to feel completely confident that this issue is resolved, but I am cautiously optimistic. We shall see.

It is definitely worth a try.  I’ll give it a shot.

 

There is a big “however” involved here though.  The phone (or maybe T-Mobile One UI) has no business changing a setting that I have deliberately made.  That is not to say that on a case-by-case basis the phone/T-Mobile shouldn’t opt to use cellular or wifi.    In this case I would interpret that to say: “Unless there is a reason not to, I very strongly suggest that you use ….”.

I do have to say that I may have been incorrect on what was going on with specific reference to the S22 with the release date firmware.   I assumed that the phone was changing to cellular preferred, and that cellular (4G in my area) just didn’t work well.  I now believe that there were two things going on.  First, wifi calling just didn’t work at all with the release date (factory) firmware.  That is, it was completely non-functional   That would explain why the phone was constantly reset to “cellular preferred”.  Second, 4G calling had major problems that resulted in at least partially unusable calling (the first 5-30 seconds of 50% of the calls) was the problem.

Starting with the first (around 3/20/22??) firmware upgrade, wifi calling suddenly (apparently) started working.  When I had wifi calling turned on voice call were now 100% clear.  Suddenly I no longer had my preferences reset to “cellular preferred” except when I left home.  When leaving home it will sometimes change to “cellular preferred”, but when reaching home to would revert back to “wifi preferred”.  I still say it shouldn’t do that ever though.

One of the reason I misinterpreted the major cause of the problem was that the phone UI does not clearly state the status of the call -- wifi vs. cellular”.  That is still the case.  It really wouldn’t hurt the to note that in that screen.  There is plenty of room.

So, at least for the S22 there is good news!  Still, T-Mobile needs the fix the “preference” problem.  T-Mobile also needs to train their support people better.  There was apparently at least a month where the S22 wifi calling didn’t work.  Support should have know that.  They didn’t.

You’ll get no argument from me that this fiasco should never have been allowed to happen. Assuming that changing this setting finally puts a stop to the problem, it is clear that the tech support people at T-Mobile know nothing about Samsung’s efforts to “improve” its products’ network performance by overriding user-applied settings. I would have left T-Mobile long ago over this single issue if I could have found a better deal with a different service provider, but I couldn’t, so here we are. I have often wondered what other user settings might be getting altered without my knowledge, but I’ve never caught one in the act. All of that aside, I now believe that Samsung was the “villain” all along, but I blame T-Mobile for not understanding what Samsung has been doing to its customers in a misguided effort to make its products look better.

Alas, after several days, my phone spontaneously changed my wifi calling setting back to cellular preferred, so turning off the “intelligent wifi” setting was not a permanent solution after all. I am left to conclude that this “feature” must be baked into the software, and immune from deactivation by the user. Oh well, it was funwhile it lasted.

I have the same problem. I do not have good service at my home so this is a big pain.  I tried the solutions on here and I don't want to pay for an app so the solution I came up with is to put my phone in airplane mode and then enable my wifi. Cellular preferred is no longer an issue. Only down side is I have to remember to take my phone off airplane mode when I leave the house. Oh and my phone is a OnePlus. If that doesn't prove the issue is TMobile, IDK what does

So here’s my problem. I’ve had poor cellular reception for over a decade at my home, so I had T Mobile  send me a 4G LTE cellspot, which works great.  But with my new 5G phone, it refuses to use 4G and keeps trying to use 5G towers, which do not work in my neighborhood. They work very well elsewhere in my city/county, but not at home.  So I’ve tried to use WiFi calling at home, the phone says it’s using it, but it will not connect nor do I get any incoming calls. I have it set to use WiFi and not cellular preferred, it doesn’t matter as it always tries using the cellular network. The phone keeps trying to use the 5G towers which suck.  So my only solution is to turn WiFi calling off and manually change my cell service to 4GLTE while at home (so I’m using the cellspot), and then remember to change it back to 5G when I leave the house.

Setting the preferred cell network at home to Automatic (5G on/ 5G/LTE/3G/2G) won’t work either, it won’t use the full bars LTE instead of the nearly non-existent 5G. 

Alas, after several days, my phone spontaneously changed my wifi calling setting back to cellular preferred, so turning off the “intelligent wifi” setting was not a permanent solution after all. I am left to conclude that this “feature” must be baked into the software, and immune from deactivation by the user. Oh well, it was fun while it lasted.

I'm truly sorry to hear that. I've been researching this problem on a friend's Samsung phone for a long time. (It does not occur on my own Pixel 5.)

 

I really wish somebody somewhere would fix this problem.

This has been a long ongoing problem.  I have had it happen on many phones including now on my S22 ultra.   From what I’ve found out it is only on Samsung phones and only on T-Mobile. 

Every time it happens I call T-Mobile.  Yes, it is a PITA but if everyone does it maybe they will take notice.

WiFi calling and HD calling rolled out on Sprint before my GS8 replaced my GS3, and it worked flawlessly. Handoff from my killer WiFi to cellular & back no problem, ever. Even in my expanded-wire plaster, wire & lathe walls (1940’s) WiFi calling gave me HD calls all over the house …

… now disabled, a phone means life even more than the ‘maybe I need 911’ of years past. The merge got me my first T-Mobile SIM -- and bad WiFi calling, so I went back to the Sprint network, until I had to go to a new T-Mobile SIM -- WiFi calling was improved … but I’m now in ‘preferences’ v. ‘settings’ land like most every post here. Been to tech support -- forced to the Sprint side. Pushed to buy a phone at every turn, go to iOS, completely migrate to a T-Mobile account … get a Cell Spot.

No reason to expand TMo’s 4G-LTE by giving them free data, free run of my LAN, and free power, for an unregulated, unlicensed, cell tower, which will shut down as soon as power fails. I currently do better with my Ooma VoIP setup.

In my case, TMo 4G LTE is usable 1 meter inside the house, entering from the east (front). The middle is a 4G dead zone. The north window in my office can see 5 bars of ATT 4G LTE and tries to use it - but the power drops to minimum necessary, saving bandwidth, triggering a switch back to WiFi -- after a few rounds of WiFi/AT&T ping-pong -- all cell connectivity is broken, and my number is “unknown” to all callers -- no texts, no voice mail , no calls, in or out -- but I can still browse the web just fine -- I must restart my phone to restore service.

Done the support orbit for two weeks -- same exact story as everyone else.

I suspect that Samsung struck a data deal with TMo, that must use cellular data to satisfy, because if it used WiFi, it would be trivial to snoop and see what’s being forwarded … if this hypothetical is in any way correct, we’ll be very unhappy with such a dark alliance.

So, TMo and AT&T are not playing well together --- but what can you do?

This is a patch - it’s ugly - but it will keep you online and able to use 911 in an emergency, without a restart and a password. Three steps:

  1. settings→connections→WiFi→[three-vertical-dots, upper right]→advanced→switch to cellular→off

Now, go someplace where you do have TMo coverage, or this will glitch.

  1. settings→connections→mobile networks
    1. verify that T-Mobile is the Network Operator
    2. set it manually if you must
    3. Data roaming→off

Final Step

  1. settings→connections→data usage→mobile data→ off

With those 3 settings in place, my GS8 now pesters me relentlessly with a system dialog asking for permission to search for a better data connection -- why my WiFi isn’t ‘supremely endowed enough’ for their liking is impossible to fathom without considering hypothetical situations such as those expressed as my personal opinion above.

I’ll happily ignore and cancel a fast system dialog that self cancels as you type a text or e-mail. Far less painful than 6 reboots on a Sunday afternoon. It keeps me from getting kicked to the curb by AT&T, which clearly does not approve of playing ping-pong - it’s a waste of cellular setup resources - the most expensive connection in the game - no wonder they kicked my T-Mobile data-roaming to the curb.

Side note, the phone won’t scan for other Cellular Data networks if it’s connected to one, so this happens only in fringe cases and ‘sturdy’ construction -- and no, 28GHz and 39GHz 5G won’t do any better - it will do far worse - you’d need 100GHz to walk through the mesh in my walls, unscathed.

I’m unhappy, have been disrespected, and unacknowledged.

I’m patched well enough for now -- but it’s not a solution. As far as I’m concerned, I’ll let the US DOJ have an image of my phone’s firmware …

I’d like to refresh this very old thread.  T-Mobile still refuses to fix this issue.  I am now on a Galaxy 23.  The same thing has been going on 4+ years. 

They still “automagically” change this setting to Cellular Preferred.  They have no business ever touching this setting. It is simply a customer preference.  A preference should have nothing to do with what is actually happening while a phone moves. 

 

What should happen (obviously) is that when a phone move to a location where there is no Wi-Fi they should (silently) change over to the cell network.  IF the customer has Wi-Fi preferred and they go back to a location with Wi-Fi they should silently change over to Wi-Fi.  There is absolutely no need for this user preference to ever change unless the user changes it manually.

I have tried to explain this simple concept to T-Mobile reps on at least 7 occasions (including over an hour today).  For whatever reason they are completely unable to understand this simple concept.  This is very, very frustrating!

ONCE I actually got a rep who understood the issue the first time I explained it.  She finally said she’d refer to up the line.  Obviously nothing happened (in 18+ months).

I don’t understand why T-Mobile is so resistant to fixing this issue.

BTW, I know that Verizon does not do this.  I don’t think AT&T does either, but I haven’t tried them.
