After my update to marshmallow last night, (I have T-Mobile) Iam getting this erroe when I have WIFI calling enabled.
Error: ER05 "invalid SIM" your SIM card needs to be updated for WI FI calling service compatability. please contact TMobile customer care.
Does anyone know why this error after I updated to 6.0 ?
