Whenever I try to send a MMS from my OPPO F1s phone I get an error meesage stating "User doesn't exist".
I have checked my MMS APN settings and they all look correct. I have also tried restarting my phone, but with no luck.
Has anyone ever encountered this?
Solved! Solved: Go to Solution.
I have the same problem. Sometimes I can send MMS other time I can't. The times I can I assume it's because the picture is small enough to send.
I've asked Oppo how to fix and the settings pages on the phone I have (F1s) don't exist.
So if it was size of the MMS, how did you fix the problem?
Cheers and thanks
@Willo_1 The size of the file you are sending will need to be reduced. I believe the max file size for MMS is 500kb.
Photos can be decreased by using separate software, some phones may do this automatically (I know my S8 does). A video would need to be made shorter or have the quality reduced.
