My iPhone keeps signing out of iMessage repeatedly, every 7 to 10 days.
I updated the iOS to 16.3.1 but no use and the error happens again.I don't use Cell data for internet and switch off Location for battery life, I don't know is that the cause or some internal flaw!
iPhone 8, iOS 16
To activate iMessage and FaceTime using your Phone number
First, check to know whether you have an SMS plan enabled at least for One SMS*** with your carrier. Contact your Carrier (Cellular Service Provider) the agency that issued the SIM to you
If your iPhone is used with a carrier not found in the wireless carrier articles, make sure you can send and receive international SMS. (One SMS*** Only)
If you can't turn on or sign in to iMessage or FaceTime - Apple ...
*** You may not have an SMS plan enabled by your carrier for the SIM/eSIM that you use on your device. Apple Inc does not provide SMS services.
I have a SIM which has a pre-paid plan and this happens on that SIM and the carrier is not found in the wireless carrier articles. So i deduced it could be the type of Plan that is triggering this.
Thanks for your kind attention. The cell numbered is verified already and as I know it's a one-time process of sending SMS and the rest is worth apple servers and framework.
