iphone on edge during roaming
When I am connected to my local provider, I have 4G or 5G depending on availability. When I travel abroad, I have EDGE! I also have a local phone using the same network provider and there is 5G availability where I am (4G for older phones).
I have tried everything:
- Factory reset
- restart
- update to latest firmware
- update internet settings
I called my network provider and they said they don't know. I've read other people are facing the same problem. It is not phone related as I cannot have 4G/5G in one country and 2G in another one.
Any ideas?
