Iphone 6plus Att call drop issue
I am using Iphone 6plus. It would be having full signal. While making any voice call, the signal bars drop from 4 to 1. LTE changes to 4g. Call would fail. I have tried network reset, iphone reset, replaced the sim card from ATT. Nothing helped. After making voice call, the call fails and then shows No Service which restrores after sometime.
never having issues with data.
