My iPhone notified me that I couldn’t make or receive calls or access my mobile data until it had been updated to iOS 15.3. After I updated it, it told me that the mobile update had failed and I remain unable to use my data or make calls, even though my phone is updated to the new iOS. I’ve tried restarting it A LOT OF TIMES, doing a network reset, settings reset, factory reset, nothing works. The SIM card works on other phones and I am able to use my data in them.
Try this -> optimize the range of the mobile network, see this Apple article: If you see No Service or Searching on your iPhone or iPad
And this article doesn’t help me at all, already went through it
Did you really read that article?
Did you contact your Carrier?
And If your carrier confirms that there's no issue with your account or network, but you still can't connect to a cellular network, contact Apple Support.
How do I optimize the range of the mobile network? And this article doesn’t help me at all, already went through it
Already did that. Thank you tho
Exact same problem. Everything I have tried has not worked. Starting to suspect the new iOS has broken older devices so they can make money of us.
Mobile data update
