I've had this problem for the last 10 days or so, although I can still use texts & data. I tried all the actions in the 3G switch off advice but no luck. My phone is supposed to be 4G enabled. However the Network Mode in the phone's settings says LTE/3G/2G. Do I need a new sim from ID, or is there anything else I can do?

Why does my Samsung Galaxy A3 (2016) no longer make or receive calls?

Did you purchase your A3 (2016) directly from Three UK,
If not, the handset can’t use the 4G Calling network service on the iD Mobile network.
