Has anyone come across this error message?
I installed a new SIM a week ago and the message is coming at me every 30 seconds....arhhhh.
I have had the new sim in 2 different Samsung models and exactly the same message appears on both phones.
Google says this is a common problem easily resolved (ha)....I have tried several of the suggested fixes....Restarting, Shut down, Reset network, Clear Cache , Soft Reset,.
The next fixes are to Modify Prefix (put a comma in front of the Prefix) or Activate radio turning on IMS over SMS.. .. I have no idea where to start with those.
I have spoken with 'Technicians '...that have just wasted my time.
Can anyone help?
