I cannot recieve calls, sometimes the phone rings for a second then it gets cut off and I get a message saying that I missed a call. Other times the other person has told me the phone rings and then goes to voicemail when trying to call me but nothing happens on my side. People have to call me on WhatsApp to get through. However I can make outgoing calls with no issues. Have reset network settings, roaming is enabled, reset and checked APN settings, tried different carriers none of which works. Very very frustrating.
