Can't send/receive MMS on Wi-Fi

M

I've been having some trouble with sending and receiving MMS while on a WiFi connection (so almost all the time) since I have stated using my T-Mobile sim on my unlocked Samsung Galaxy S7 Edge phone from Sprint. Everything else seems to work fine e.g. calls, SMS, LTE, but when it comes to MMS it's a complete stalemate. I've tinkered my APN settings in almost every permutation I found online, and I don't have an option for Wi-Fi Calling so there's nothing I can seem to do on that front. A solution to this problem, so I can start receiving MMS again, would be great.

I have the same problem on my A51. The app says it's not compatible with my system. I can't delete it or update it. I can't send or receive mms unless my mobile data is on, and if I forget to turn it off..  I bought a wifi capable phone because I have wifi service. I don't use my phone often so the cheap prepay plan unlimited talk and text is good enough EXCEPT I can't receive mms messages from my grandkids unless my data is turned on, which is limited.  I'm about to toss tmobile service  which I've been loyal to for many years.  There is no reason I shouldn't be able to send or receive mms over wifi only but I cannot. Tmobile says it's a samsung problem and visa versa. So? ??? My grand kids send a lot of pics and fb messenger is not an option. I receive all other data over wifi so why not mms thru text messages?

I can't receive or send messages or I can only message one person I've tried everything and I really don't want to do a hard factory reset on my phone

i know back with Sprint the one phone i can remember this happening to was Sammy phones. i have ran LG and HTC most of my life and if i had a really bad signal i could switch into airplane mode and the phone would stop trying to pull in whatever signal it couldnt find and instead pushed for wifi to handle things..the Sammy line for whatever reason could not do that (i think it had to do with their own texting app. but now they use GM so things might be different now). might have changed over the years..try switching into airplane mode..then turn on your wifi then try again and see if it improved or not.

Correct. Whenever I'm up on my Hilltop where there's no cell signal at all I have to resort to Wi-Fi calling. However that's when the problem starts when somebody sends me a screenshot or any image. Once I come down the hill and back on 4G LTE or 5G it pops right in no problems whatsoever so something to do with T-Mobile's Wi-Fi calling.

This has been happening long before their security patch. It used to work fine and then all of a sudden about a year ago I started having issues receiving and sending texts when Wi-Fi calling is on.

so your issue is mainly linked to wifi/WFC/texts?

from what im seeing if the problem crops up with a S21, 22 or S23 its more than likely the last Samsung security patch that was kicked out..this issue with loss of signal/data and texting issues have cropped up after said update..which if this is the case Samsung will need to get a fix on it kicked out.

My s22 has same issus.  If I reboot my phone and hit send again sometimes it will come in or go out, but this is very annoying with T-Mobile wifi calling feature.  When it does work, it just takes forever to receive or send an image. I have to tell people to email me instead of texting me an image. It's very frustrating.

 

And when I switch to the Google messages I still have problems so it's definitely the T-Mobile network.

Yes, I followed those instructions.

I've actually figured out what's going on.

The http://mms.msg.eng.t-mobile.com/mms/wapenc URL works over the cellular network - but times out over WiFI.

And it's not just my WiFi - try e.g. https://www.isitdownrightnow.com/mms.msg.eng.t-mobile.com.html. So… why is it only working over the cellular network?

I'm having the same problem on a OnePlus 8 phone.

 

I've switched the APN protocol to IPv4, and added “internet+MMS" to APN type - but still cannot send or receive MMS without a cellular network.

Go to your apn settings.

If you cannot edit your current apn, add a new one and make it identical.

In the APN type field, copy your original settings except: if it says internet, change to internet+MMS. if it does not have internet, add internet+MMS. should look like this:

default,supl,internet+MMS,hipri,fota

or similar

So this has been an ongoing issue for me for 2 years on a Pixel 2XL and a Pixel before that.

I think I have finally figured it out. I noticed mine would work sometimes and not others.  Started looking at making profile changes, etc, and noticed that the default T-Mobile profile prefers IPv6 over IPv4.  I live in an area where we have Time Warner Cable/Spectrum and their IPv6 is pretty shady at times.

Went into my WiFi router and disabled IPv6, my MMS has worked flawlessly ever since!  My roommate who has a Pixel 3XL, solved her problem too!  I believe it actually has nothing to do with the phone or the service, but actually with IPv6 and your internet carrier.  Try disabling IPv6 on your internet router and I bet it will fix it for you too!

Now, I have to figure out how I can disable IPv6 just for my device so other devices in the house can use it.

I have had the same issue on my LG V20 for a year or so now. I finally found a solution that worked for me by accident. If I use T-Mobile Digits and the native SMS app on my LG (only the native one will work) everything seems to working as it was meant to. I only found out about digits a few days ago (not sure why T-Mobile is not advertising it). Digits allows you to use multiple phone numbers on one phone (through cellular data connection or WIFI) and also allows you to use your phone number on other devices as long as it has an internet connection. Some phones have the Digit app as a native app (the V20 does) but you can also download the app. The native version is not activated by default, you have to go to the Digits web app to activate it. It was a bit of a convoluted process and I'm not 100% how I managed it but when I log into my T-Mobile account and click on "phone" it showed me a Digit link below the image of my phone. After clicking that it asked me if I wanted to activate this on my phone. Once activated you have to go to your phones settings, accounts and add the digits account (not sure if this is fully necessary but this will allow you to use multiple phone numbers). Once activated when I opened the LG messenger app on my phone it showed me a magenta sim card symbol next to all my conversations. This now means all the conversation (or at least the new ones) will also show up on which ever other device you register to it. You can even log into it on a web browser at T-Mobile DIGITS . I'm not 100% sure how this makes it work but I think its because Digits is fully web based it sends all the info as pure data not some hybrid MMS/SMS thing. Hope this works for other people too.

I had the same issue with my Sprint phone that I brought to T-Mobile.  When connected to WiFi, I couldn't send or receive MMS messages or participate in Group Chats.

In the Messages app, under settings, there was a Chat Settings menu, that was supposed to have options to enable MMS and Group Chats over WiFi.  When I attempted to access the Chat Settings menu it presented a dialog box that said I must register, and they would text me a message with a verification code.  When I attempted to register, the text message never arrived.  I'm guessing it might have been attempting to register with Sprint.

I fixed the issue by installing the Messages App (Google LLC).  Now I can send and receive MMS and Group Chat messages, on and off of WiFi.  Under the Settings menu -> App option, I changed my default messaging app to the Google one.

Hey, @magenta4936749​!

I did some digging and was able to find that there is a known issue with Galaxy S7 Edge models that have an issue when handing off WiFi to the data network when trying to send MMS'. My recommendation would be to talk with Tech Support via 611 or T-Force (Facebook/Twitter) to get a ticket filed with our Engineers. By chance, have you already done this? If not, give that a shot and keep us updated on the outcome of the ticket.

eplerd

This doesn't need Root, just a version of the Samsung tool (Odin) that is modified to ignore the model checks (flashing G935T software onto G935A phone)

Since you mentioned root - I presume you are somewhat tech-savvy yourself?

Hopefully T-mobile moderators don't mind the links to firmware (I don't have time to read all the "terms and conditions")...

Anyway, it was kinda scary for me as friends couldn't afford to buy new phones (never done before) , but someone I work with told me if it didn't work Best Buy has a samsung rep who would reload the Stock AT&T software on it so you only lose time trying it and can then restore your files/apps after...

This doesn't trip the Knox security bit, nor does it cause e-Fuse issues, you just need to hope there is Tmobile software out there at same bootloader (BL) version as you are running now -- I can't do this to my S8 Active as TMO is BL v1, and ATT is BL v2 😥 ...I have to wait until TMO updates to BL v2.

The latest firmware on TMO is G935TUVS4BRC1 so you'd need to locate that from a reputable source

(DISCLAIMER - I CANNOT GUARANTEE sources of firmware - USE AT OWN RISK)

I did a quick look and found the latest firmware on this thread:

https://forum.xda-developers.com/tmobile-s7-edge/help/galaxy-s7-edge-tmobile-stock-rom-t3729776

Patched ODIN loader is on this thread

Patched Odin 3.13.1 | Android Development and Hacking

Anyway, if you wanna try yourself there are other things to research:

Put phone in developer mode and enable USB debugging (they say it helps)

Use Smartswitch to back up data (move private files to a folder before backing up - flash will erase phone)

Put phone in recovery mode and do factory reset, then reboot, then do clear cache partition

Put phone in download mode and connect to USB Port (do NOT use USB3 ports - they can cause issues for some odd reason)

Open Modded Odin, put files in each of the 4 boxes labeled (BL, AP, CP, CSC)

Click <START> and pray LOL

Watch screen, in about 5 min or so it should finish - but be patient

AGAIN - THIS IS ALL AT YOUR OWN RISK - Tmobile won't support you if ya mess it up and I 'm not liable as I barely know how to do it myself (But it wasn't that bad - but I'm an IT guy by trade)

do lots of research if doing yourself -

GOOD LUCK

M

Wouldn't that require for me to root my phone anyway?

M

That was one of the initial steps I tried, but no, the safe mode didn't help.

The other option is find a VERY tech savvy person to put T-mobile firmware on your Galaxy S7.

My friends ported their unlocked S7's from AT&T over to Tmobile and had the same issues intermittently.

so I downloaded firmware G930TUVS4BRC1 off of a developer's forum ( Android Forum for Mobile Phones, Tablets, Watches & Android App Development - XDA Forums  )and used the Samsung tool "odin" to write it to the phone.

This totally erases the phone (best way) but you can back it up first using Samsung Smartswitch software then restore it afterwards.  You'll need to re-login to apps that save login and redo some settings but it's worth it.

Now their phone boots up with T-mobile logo not AT&T and looks just like a G930T (T-mobile version of Galaxy S7)

This is NOT for the inexperienced person as it can cause issues if done wrong but they now have ZERO issues....and didn't have to go out and buy new phones at great expense!

To moderators: if this sort of post isn't allowed let me know and delete it, but this DOES work and it's not that hard to do!

I just wanted to make sure you could use the data from your Wi-Fi connection. Since alternate apps are working, sounds like using data from your Wi-Fi isn't an issue. Have you tried the phone in Safe mode to see if MMS works? We're really coming down to the wire for steps we can take on your phone. Wiping the cache is my next suggestion but a complete reset would be the last option you could try on the phone.

M

It wouldn't help with receiving multimedia messages, though.

M

I mean if I open a web browser while I'm connected to WiFi would I just use my WiFi connection, not data, to load a given page? Anyway, since my MMS is working on an alternate texting app while connected to WiFi, I think that's established.
