I'm having the same issue - just did a BYOD w/ my XR from FI back to Xfinity and can not send MMS - I can receive MMS but can't send. Chatted w/ Customer Support yesterday and after i told them i had done multiple network resets w/ still no joy, they suggested i escalate the issue.
I'm actually thinking of escalating to ATT.
Thanks for posting everyone! It sounds like an APN setting issue--glad to hear the reset worked for you uf20wop.
Well i did a full reset twice on my XR but no luck - still can't receive or send MMS. However...i did put the sim in my moto x4 and MMS now works.
Update - So apparently the trick is to do a full factory reset AND set it up as a new phone. Now it works.
markjreardon, thanks for posting your fix! Appreciate your support of the community. Glad you were able to get MMS working.
