Cannot receive SMS/MMS

GeekBone

Has anyone had any recent luck with TMO? I have a 3a that is working beautifully but I can't get the MMS to work. I have read all the threads here but most of the suggestions are for previous OTAs, My 3a is currently running OTA 21 and I have tried legacy and current APN settings. I have a 3a with TMO and Android and I copied the MMS settings from there and still nothing.

I am concerned it is related to the whole VoLTE/5G situation but regardless, I am not sure what to do at this point.

If you mean T-Mobile (or a re-seller such as US Mobile) for USA, these settings work and are used by several people successfully (with either T-Mobile or US Mobile as their carrier):

You need 2 APNs (1 for Internet, a second for MMS) and they can't have the same APN value. So set up 2 like this:

Used For: Internet
Name: T-Mobile Internet
APN: epc.tmobile.com
<User Name and Password BLANK>

Used For: MMS
Name: US Mobile MMS
APN: pwg
MMSC: http://pwg.mmsmvno.com/mms/wapenc
<Proxy, Proxy Port, User Name, Password ALL BLANK>

Please confirm, but it should work.

@rik Holy crap! It worked!

@rik One more thing.. the images I attach rotate -90 degrees. They look normal in the gallery but when I attach them they rotate. Any suggestions?

This is normal.
The orientation information is read and understood by the gallery app but not by the messaging app.

Also MMS pictures are often resized to fit the data length limitation, in this case I bet the messaging app do not check the orientation metadata and it is send either vertically or horizontally depending on the default.
Check if an issue is open for the messaging app and if not you can file a feature request.

As a workaround you might want to edit and resize the picture yourself giving it the proper orientation.

In the future a "combined APN" (Internet + MMS) will make this more intuitive: for now we struggle with counter-intuitive tinkering.... but YES it works! Here is the "not quite ready may need re-worked" PR that will provide a combined APN, so you can follow if you are interested: https://github.com/ubports/ofono/pull/28

@applee I don't have this problem with my N5, but I will play around with it some more.

I still think the N5 has the best UT integration out there. It is such a great little phone. Too bad it won't be able to handle VoLTE so I am trying to switch to the 3a.

Regardless, thanks for the tips. I appreciate it!

Good to know.
Thanks.

I can confirm that on Mint the PWG APN and MMSC work for me too- both 3g and 4g, send and receive, as long as I do not turn on wifi. If I turn on wifi and need to send a MMS message, must turn off wifi and reboot. Then MMS is back in business. I am using two APN- one with the default "wholesale" APN for Internet, and the PWG for MMS.
