An update is required to use cellular data on this iPhone. [iPhone 7]
Dear all Apple team,
I have a problem with Cellular
I updated my iPhone to iOS 14.7.1, I can no longer use the SIM card
I did the following but did not get any results …
- Restore to iOS 14.7.1 [fixes for 30 minutes but shuts down again]
- There is no problem with the SIM card [I changed the SIM]
- Check hardware problem [no found problem]
Thanks
