Fix / solution for “This Command is not allowed in UserBuild”

Just make sure that in that line of your SIM 1 (“”AT+EGMR=1,7) or SIM 2 “”AT+EGMR=1,10, add a space between the AT and EGMR for example from AT+EGMR=1,7 to AT +EGMR=1,7. Doing this will accept when you press the send at command. It is all very simple and easy to do so when solving the above MTK Android error.
