Move to a different location
Sometimes, the issue does not exist on the iPhone but the signal at the location. When users travel to another place or their cellular signal gets weak due to some glitch.
So if you are persistently getting this error only at a particular place, then we suggest moving to a location where you can find the strong signal strength. Now check whether you are still getting this error or not.
Contact the Cellular Network Provider
If none of the methods are working for you, then there must be some problem with your cellular plans or the SIM Card. So we recommend trying to contact your cellular network provider and get it checked.
