TMobile issues

kmsgli · 30 Jun 2021, 01:13

I assume its carrier based but anyone having any SMS/MMS issues with Tmobile. I have been checking back every couple months to see if it is fixed as I badly want to use my old pixel 3a to go completely google free.

Fresh install phone calls work in and out SMS works to send but I can not receive SMS or send or receive MMS.

No matter what APN settings I play with I cant seem to receive SMS.

Anyone else running TMobile on a pixel 3a?

@kmsgli You can start receiving SMS if you change from 4g to 3g. As far as the MMS I still don't know how to fix this.

@kmsgli Also, if someone has Signal, you can use the Axolo app(Signal-compatible) to easily send and receive MMS. I'm going to go to my local T-Mobile store soon to see if they can help with the MMS issue.

@davedanger MMS will not send or recive if you are connected to wifi, this is a known issue. I use Mint Mobile which is T-Mobile, and have not had many issues. I can check next week to see it i can get a 7day T-Mobile plan.

Internet
Name: T-Mobile1
APN: fast.t-mobile.com
MMS
Name: T-Mobile US LTE
APN: fast.t-mobile.com
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc

These are untested: I do not have tmobile, once upon a time I did, and i know this should be the format used. Will check in a week or so.

Also Ubuntu touch does not support CDMA "verison or sprint" and a lot of tmobiles network is sprint after the merge.

@davedanger The 2g/3g worked right away for sms thanks!

The off wifi did not seem to help with MMS. Maybe the APN settings need to be adjusted?

davedanger · 5 Jul 2021, 04:35

@kmsgli I've tried different APN settings and haven't been able to find anything that works yet. That's the one thing that's keeping me from using it as a daily-driver. It's definitely my favorite mobile OS.

davedanger · 10 Jul 2021, 02:25

I've seen that some people claim to have had success by loading Android PD2A.190115.029 rather than the recommended Android 9. Can anyone confirm that?

kmsgli · 11 Jul 2021, 15:30

@davedanger Whats interesting is when someone sends me an MMS it tells me error check APN so it knows MMS is coming in but can not make it show up.

Other than that I am daily driving this phone with good success I just ordered a new pixel 3a since the screen on mine is destroyed and used they are rather cheap, i think i am making the full time switch!

@davedanger
I'm giving that a try, it might work. Before I reinstall UBports, I'm going to see if my simcard will even work in this android phone using build Android PD2A.190115.029.

davedanger · 11 Jul 2021, 18:35

@grhmhome I tried it without success, but I'm also no expert on mobile operating systems either. Hopefully you can find something I couldn't.

davedanger · 11 Jul 2021, 18:37

@kmsgli I'm getting the same message

kmsgli · 11 Jul 2021, 21:30

@davedanger Curious if its the APN / TMobile or the OS at this point?

davedanger · 11 Jul 2021, 22:09

@kmsgli I know in Europe they're not having this issue or being able to correct it, so I think it's probably some sort of APN issue.

davedanger · 11 Jul 2021, 22:54

Don't know if this helps, but I just received an MMS error message and I replied back saying, send the pic on Signal, I can't receive MMS right now. They replied back that they weren't sending a pic, they were creating a Group Message. So Group Message creates an MMS error message. Hope this might help any Developers.

@davedanger, @kmsgli and others: I have gotten MMS (send and receive) and SMS receive (send was always working) to work on a Pixel 3A XL with US Mobile (T-Mobile network) but there are a few oddities. Let me explain what I did:

Background: I could send SMS but not receive normal SMS when on wifi OR send or receive MMS. I was on the "stable" branch but also tried RC and Devel. Note that LTE data and 3G data seem fine, as does all calling.
Installed MMS patches from here: https://forums.ubports.com/topic/5100/the-mms-lost-story/124?_=1626709684067
- Note: I had to unmount like this before applying the patch that would update repowerd: sudo umount /usr/share/repowerd/device-configs/config-default.xml
- After applying all patches and restarting, retried SMS and MMS. Still the same (only send SMS, no send or receive MMS.... what I mean by no receive was not even the error message, the messages just don't come)
Disconnected wifi (so on LTE only). Still could not receive SMS or anything with MMS.
Changed from LTE to 3G (wifi still off). Still could not receive SMS or anything with MMS.
Rebooted (with wifi still off): after reboot, SMS and MMS came! Also I could send MMS! I tested with .jpg and animated gifs. All came!
Enabled wifi: then could not receive SMS or anything with MMS again until reboot without wifi.

So I repeated that process a few different times with slightly different scenarios. But in short, at least for me MMS (and receiving SMS) ONLY works if the phone boots with wifi off and wifi never gets turned on. Once it is turned on, broken again until reboot with it off.

APN settings were obtained online (and the did NOT match what was installed automatically when inserting the SIM). Here are the working APN settings for MMS (again for US Mobile, T-Mobile network):
APN Mode: "used for MMS"
Name: US Mobile
APN: pwg
MMSC: http://pwg.mmsmvno.com/mms/wapenc
Proxy: <blank>
Proxy Port: <blank>
User Name: <blank>
Password: <blank>

Below are the T-Mobile settings auto-installed when i put in the sim (but I disabled this setting and added the above as a separate entry). Note these settings did NOT work, even if booting "with wifi off" so I think these are bogus at least for the US Mobile sim I have.
APN Mode: "used for MMS"
Name: T-Mobile MMS
APN: internet2.voicestream.com
MMSC: http://216.155.174.84/servlets/mms
Proxy: 216.155.165.50
Proxy Port: 8080
User Name: <blank>
Password: <blank>

So at this point, I have a fully functioning phone if I keep wifi disabled and only use cellular data. I am not sure if there is any log I can check to see what happens when I enable wifi that effectively breaks receiving SMS and all things related to MMS??

rik · 21 Jul 2021, 21:00

Minor addition: using a Nexus 5 with the same SIM I am able to receive and send SMS and MMS with no problems with wifi still enabled. So it seems to be specific to the Pixel 3a rather than to TMobile that this issue exists.

Can anyone outside the USA confirm that Pixel 3a SMS and MMS work without issue when wifi is enabled?

rik · 22 Jul 2021, 16:47

One more update: things aren't totally reliable with receiving SMS and MMS (sometimes / often don't get the messages until I reboot for example, and still get the MMS error message sometimes). So I still haven't seen SMS receive or MMS work when my wifi is on, but it may not be directly related. Anyway, more testing and debugging needed. If anyone can point me at the right logs to look at it may give some clues?

Again, can anyone not in the USA confirm Pixel 3a SMS receive and MMS send and receive working reliably?

Nutmeg · 22 Jul 2021, 18:26

@rik I am having a terrible time getting these patches installed. Would they be the same for the 3a? I am using Puretalk, not T-Mobile but not getting any SMS. They are going out
