This is my second trip to the USA where roaming doesn’t work. It connects to AT&T and even displays 4G however nothing actually connects to the network.
My plan used to work with roaming however the last 2 weeks and trips to the US it has stopped working.
Hmmm this is strange. Your phone is connecting to the network so it sounds like everything is configured correctly on our end.
Are you able to check with AT&T to see if your mobile's network settings need modifying?
