Cellular Service / Mobile Service shows unavailable for iphone 16 pro
Need help. I bought my iphone 16 pro from canada; which has one physical SIM and another eSIM option available and with no restriction or no network plan. I setup up the phone myself and started using both physical SIM (of one operator) and eSIM (of another operator). I have used around 9 days like this with no trouble.
One fine morning, the eSIM disappeared from settings and stopped working. I restarted the device and I immediately checked with my cellular service provider and replaced QR code for eSIM. Then I reset the network and even reset all settings with data. Then i setup again restoring data from icloud. But unfortunately, the Mobile Service / Cellular Service shows unavailable. Hence, I could not add eSIM using QR code.
I need suggestions from the community to resolve this. hats off to the experts !
Regards.
TT
