This too. I forgot.
I recently encountered this issue even with att after switching from Verizon. I could receive calls and texts but no data until I registered my imei with them
So I’m going to switch probably in the next week. I have two iPhones which I know won’t have any issues, but i have a Series 4 and a Pixel 2 XL. Will those present any issues?
Don’t really care if WiFi calling or VOLTE won’t work on the Pixel.
