Alright, so I just got my L5 set up with T-Mobile (previously with AweSIM). Sms messaging works normally, but when I send a picture, chatty creates a separate group chat including me (with no phone number assigned) my recipient, and an unknown contact (my new number). Its like Chatty doesnt recognize the new number I am using. Is there a way to fix this?
-update- it’s received pictures that cause this, not sent pictures.
MMS has been working out of the box for me since I received the phone, although it acts wonky sometimes. Instead of pictures loading automatically in Chatty, they will be displayed as links to click on .
MMS works for me since a long time, I don’t remember exactly but at least since half a year ago. But I think it only works when the APN used for MMS is the same as the regular mobile data APN, and that depends on your provider, you may be lucky or not. See State of MMS on Librem 5
Not all heroes wear capes. The instructions worked for me, but not for using the APN “fast.t-mobile.com” What did work was matching the default Access Point Name under Settings/Mobile with the APN on chatty. MMS appears to be functioning normally now.
