This is great. I know I'm Necroing an old thread but this was my exact issue... Weird that "reset to default" doesn't give correct settings for MMS. It was some random IP for the MMS proxy and port 80 for the default.
Best buy. I ran a test call, and during the call my phone hops from 5g+, down to 5g. I understand there's yet another calling feature called VoNR that may be compatible? Both my work and personal plans are 5g
