So got my new IP 12pro max. I upgraded my one line to a 5g plan and it updated all 7 of my lines. Been noticing data issues since I got the phone. my Data speeds are garbage. and not just on my new iphone but with all my devices. Anyone else having issues? Everytime ATT makes a change to my account i have some new issue. 2 weeks ago due to the change i was unable to get voicemail last week is the Data issue. They can't fix any of it. So was wondering if anyone has had this and has any advice
