The link is of no use .


I contacted Apple Support and they are saying to contact ATnT , I reached to ATnT and they say its unlocked from their end . I again reached Apple and they say ATnT creates a profile which may have been over ridden during the upgrade ,so ATnT has to redo it.

I am not using ATnT any more .


Should Apple as the product owner not be able to fix the problem , rather asking me to get in touch with service provider .


Can I get help in this regards!

I gt 8 Plus in Sep 2017 from Best Buy , universal SIM . I inserted my ATnT has it was good to go . I came to India in Jan 2019 and inserted Vodafone SIM and it dint work , I got in touch with ATnT and they unlocked it . Last week their was message on my screen that "you can not receive and make calls or use cellular data untill u update " . I updated to iOS 13 . The phone was updated and it again displayed the same message . However this time I was on the lastest OS . Since then I am struggling .

When I go to Settings -> Cellular , it displays error and has a message to update to latest OS .


I tried to erase the phone , I got a message , Celluar Update has failed so the device cant be activated after erasing" . So I did not erase my device .


Suggest what is the solution !
