I have t-Moble and I can not send photos via my txt messaging. I can receive photos, but can not send. Any Ideas…

Welcome!

Sorry for the trouble.

Have you verified your phone’s current settings against T-Mobiles documentation for APN settings?

What messaging app are you using? Does it throw an error or give you any indication what is happening?

Some of the messaging apps do a poor job of resizing content to meet the MMS file size limits of the various carriers. The best-behaving app I’ve seen in this regard is Google Messages. Would you be willing to give that a shot for an outbound message test?

I have TMobile and recently started having the same issues. I’m using messages.android_20230110_01_RC00.phone.openbeta_dynamic

I also tried Pulse, Messenger and Mood, all with same issues. Sometimes switching off and back on Mobile data/WiFi helps, but pictures take forever to be sent or being received.

This is the error message:

Saijin_Naib · January 20, 2023, 6:21pm

Do you experience problems on the Stable channel of Messages as well?

Cedro · January 21, 2023, 2:26am

Yes, stable or beta, same issues.

Saijin_Naib · January 21, 2023, 4:19am

Are your APN settings correct as per T-Mobile documentation?

Have you enabled any other features or changed the APN settings before this issue began?

Cedro · January 21, 2023, 4:43pm

As far as I know, yes.
I haven’t messed with the APN settings before the issues started

Saijin_Naib · January 21, 2023, 5:20pm

Can you please try resetting them from the triple dot menu in the upper right?

Cedro · January 26, 2023, 1:26am

I did. It’ll work for some time then I’d have to reset it again

I know this is of little consolation, but I’m experiencing similar on ATT/CricKet on all our units in my house. It began after ATT started to decommission 3G towers in our area last year to spin up more 5G.

I usually just toggle airplane mode once a day out of habit now -_- Should probably find an app to do that overnight for us.
