I have an iPhone12. I used to have Sprint as my carrier but now T-Mobile. The chat bot feature is not helpful either because it prompts me to sign in and then when I put in my username it kicks me over to an old Sprint help page.
I have been unable to receive MMS messages from a short code I am opted in to for about 2 weeks. I have tried reseting my network settings, I know that I have enough data to receive larger images/gifs and messages, I have tried shutting down my phone and turning it back on. The weird thing is I am still able to receive shorter form, SMS messages from this number, just not MMS and I know that other people with different carriers are able to receive these MMS still. Any advice is welcome.
