Good morning.
Now I'm in Philippines, and my Phone is out of service.
As attached, Phone can catch the career but cannot connect.
So I think it's some problem for AIS settings.
Please confirm to AIS and make activate for calling in abroad.
Non-stop data roaming is not required because I'm using local WiFi for data roaming.
The problem is phone call roaming.
At present I cannot call and receive call.
