iPhone 12 Pro Max on T-Mobile Essential NCC family plan. 

After updating to iOS 14.5, cellular data won’t work. It doesn’t matter if it’s connected to 5G or LTE, or at whichever signal strength. It doesn’t have internet access. I can only make phone calls and text. 

I have tried network reset, factory reset, and reinsert sim. I even went to the Apple store to have my phone replacement eventually. 

However, the issue persists on the new phone as well once after it was updated to iOS 14.5. 

Only solution for now: is downgrade to iOS 14.4.2 or earlier. (As of may 3 Apple has stopped signing iOS 14.4.2 or earlier)

Also, other people in my family plan with iPhone 12 models updated to iOS 14.5 have the same cellular data issue. 
There are several people on Reddit reporting the same issue as well. All currently on essential plan.

Hopefully T-Mobile and Apple is working on a fix!?
Ps. The most recent iOS 14.5.1 doesn’t fix this problem.

I have the same issue!!!

It happened last week Wednesday. My iPhone 12 pro can make phone calls, can send messages to other guys, but NO data. My data plan is unlimited. The signal bar is 5G, but no network.

I tried everything, reset all settings, erase all data and contents, that does not work. I went to the T-mobile store, they replaced a new 5G SIM card for me, but it did not work. I went to the Apple store, they thought it is a hardware or antenna issue, they changed it but still not work. After that, they replaced a new phone for me, but the issue still not resolved. They told me it has to be the carrier problem. I went T-mobile again today, I do not know what they did on my phone, but finally, it was working, it can open websites on cellular data. But again, 1 hour ago when I was outside, the cellular data just suddenly disappeared. I tried to restart, reset all settings, it does not work. I am so confusing is T-mobile restrict my usage or something else??

This is crazy that we’re all experiencing the same issue. I purchased the iPhone 14 pro max and when I first bought the phone T-Mobile were sure it was a defective phone sold to me by best buy mind you I waited for my phone for a month before I received it. I was told to return the phone and get a new one in which I did and waited an additional week and a couple days just for the same problem to continue on the new phone. now no one knows what to tell be besides they’ll call me back in 24-48 hours.

Did you get this resolved? I am having the same issue on a iPhone 14 pro max. Could you share your resolution? Thanks!

Sad to say, this has been my first truly negative magenta experience in my 6-years here. I have worked in IT for 23 years with a focus on tel-com. This issue has not been resolved. I went 3 different bout's with the ‘experts’ and they were unable to identify the source of the problem. I verified that my NCC plan SIM worked on every Andriod device as well as iPhone’s running iOS 14.4 and below. I also verified that the same SIM would not resolve cellular data on 3 different iPhones, running iOS 14.5, 14.5.1, and 14.6. I also verified that a Magenta Max plan SIM worked perfectly fine on the same iPhone that the NCC plan SIM did not.

At the end of the day, the only solution was to ditch my grandfathered plan and take a ~30/mo rate hike to get back up and running.

Pretty lame that T-mobile would not devote the appropriate resources to take care of the ~1000 cutomers who have viewed this thread.

I have been having this problem since 4/28 and reached out to Apple directly on 4/29. After 3 subsequent visits to the Apple Store WTC in NYC and a number of “genius’” being involved they confirmed un-officially that the problem is with iOS 14.5 and 14.5.1 and as far as I’m aware 14.5.2. In the store they had me backup my original iPhone 12 to my MacBook prior to their resetting it to discover that the problem was real and I’m not crazy. Switched to a new phone, same problem. I’ve of the reps moved my SIM card to a 12 Pro and it worked, but that demo phone was evidently “not” running iOS 14.5. After more calls to Apple they agreed to swap out my phone and I would pay the cost difference. Got to the store and nobody knew anything. They ended up comping the difference in cost but the 12 pro max has the same “no cellular data” problem. They swapped out another phone and didn’t do the upgrade to 14.5.1 and all works fine like it did before the update, but my backup taken when my original phone was using 14.5 cannot be restored. I’m screwed and Apple could not care less. I can live without things in the backup until fixes are made that allows for the restore. This weekend I purchased a new Apple Watch 6 and I’ll be damned but it wants a version of iOS higher than 14.4.2 in order to initialize and set up the watch. It’s unbelievable that Apple can issue such an advertised major upgrade without sufficient testing of such a big ticket item with a major carrier and then be so apathetic in regards to a fix. I’ve got an Apple Store appointment now to find a work around using a demo phone at the store to initialize the watch. Hopefully some solution will work, but at this point I have little confidence in Apple and finally admit it’s time to migrate to Android. High prices shouldn’t come with hassles.

This is circumvented by activating your iphones “digital sim” (aka: “esim” or “dual sim”) in place of the physical iccid you are currently assigned. You can complete this by contacting customer service and/or tech support, provide them your “EID” (Settings->About->eid) notice youre device should be showing your current imei + iccid network information, along with a second inactive “imei”. The second imei you see is not actually relevant or needed for your esim device  activation/switch - the “EID” is what is necessary. after providing this information to the rep, they should direct you to add a new cellular data plan by either sending you a configuration profile, a QR CODE, or manual settings (T-MOBILE.GDSB.NET)

 

once you activate your esim, you can take your physical sim out and leave the sim tray empty or begin utilizing “dual sim”

 

your iphone will now receive its intended data connection and available 5G coverage.

*may take an hour or so to register the change, you will need to restart device as well as potentially activate airplane mode for a few minutes and restart.

This happened to us with the 14.6 update from Apple. All IPhone 12s on our No credit check family plan have zero cell data although we have full bars. This makes T mobile absolutely useless - needs to be fixed ASAP

Problem solved!  I too had a “No Credit Check” account, running iOS 14.6 on an iPhone 12 Pro and for some reason had the same issue where the phone indicated it had access to 5G, but internet was not working.  Interestingly, using the SpeedTest.net app, I was able to see fast internet connection (I assume that it’s using ICMP to test the connection speed) but all other internet traffic such as HTTP or video/audio streaming was still not flowing. Working with a T-Mobile rep we switched my device to use the digital sim as suggested by Izual, but it still did not work.  Eventually I got cellular data flowing again after switching from a “No Credit Check” account to a T-Mobile Essential account.  I had my credit frozen due to the Equifax breach from a few years ago, so I temporarily unfroze it, they ran a credit check on me, and switched my account to a T-Mobile Essential plan, which actually saved me $10 per month. As soon as the switch took effect, cellular data started flowing as normal again.

I took Mike’s advice and chated with a rep who was able to step me through fixing the problem.

If LTE Only doesn't work for you:

I have the same issue but my phone is iPhone 12 Pro Max. At first I though it have the problem with my carrier then I put my sim on Android is working fine. Then, I realized it not thing wrong with my carrier. The problem I have is the combination between T-mobile sim and iPhone12 Pro max (ios14.6). The iOS 14.6 seems not to working with 5G or LTE. Then, I download the newest version of iOS (14.7 beta).  Now it works (5g unreliably, LTE reliably). I hope my solution will help your guys. 

Always try simple things first (Im sure apple support and Tmobile will make you do them and send you through the loops)

I download the new version on the Apple Beta Software Program.

iOS 14.7 and still I have the same issue.

I ended up switching to TMobile prepaid to fix this.  5G cell data immediately starting working.  Ultimately you have to get off the No Credit Check plans. The technical trouble ticket they opened for me was never addressed.

M

Same thing here I’m on TMobile Essentials NCC and on iOS 14.5.1 on my 12 Pro. 5G shows full bars but won’t load anything on my socials or in Safari. Only when I switch it back to LTE only in settings will it work

F

Having the same issue here, Iphone 12 pro, cellular data not working after ios 14.5, Essential NCC plan. No solution provided or ETA from Apple or Tmobile after providing logs with apple support or visiting Apple store. I’m seriously considering switching to another carrier since it’s been too long for a concrete answer and it seems no one is looking into the problem.

This is still not solved. Dunno how this can be marked as solved…

you do understand that the fix must come from Apple themselves correct? theyre the ones that need to get the fix kicked out or at least kicked to TMO in order for them to test it

I’m on iOS 14.7 iPhone 12 Pro Max, and I have the same problem. This problem didn’t seem to be happening back when I was in Philadelphia, but when I moved to SF, this started happening. I will reach out and see if there are any solutions.

I had this exact issue in an iPhone 12 Pro but never found time to figure out if I was affected by the “Non Credit Check” issue because my lover bear pays that bill. I can say that updating my iPhone to the 15.0.2 beta software today 10/24/2021 fixed the issue fully for me. Probably some collaborative work that went in from both parties to solve it if this fix stays permanent. Good Problem Management. Bad PR. 🙂 ):

Has there been a root cause identified?  Why would an iOS problem only affect No Credit Check plan customers on T-Mobile?

because they botched the update? any fix coming to these devices come from the manufacturer

Same problem here. NCC account, upgraded to iOS 14.5.1 and data stopped. Fix for me was migrating my account to Magenta 55+.

N

I have the same issue, I just called Apple and they told to backup my phone and reset it to default. anyone tried that?

D

5G Cell Data looks to be working for me today. I have only tried it one location, but so far so good.

S

T Mobile has decided that it’s my phone and nothing wrong with the plan. My sim runs just fine on the phone at their store that is running 14.1. Apple has been completely through the phone and it has no hardware issues. TMobile says the phone is under warenty and get anew phone from Apple, Apple says no issue with phone so no warranty. I am sure it’s a problem with the plan and 14.5 OS, T Mobile has not reason to step up being it’s an out dated plan. I am going to search another provider.

Correction: this problem doesn’t seem exclusive to essentials plan. It seems like many No credit check Plans are affected.
