Ever since I switched to Mint mobile, I was unable to send pictures, large messages (sent as MMS) and group messages. I was able to do all these on Graphene using T-Mobile. I also had an issue with data, but disabling 5G fixed it. I don't know if that's a meaningful solution.

How to get my MMS working again? Using signal as someone suggested on another lost is not an option.
