iphone 6 no service and searching
I have iPhone 6 with iOS 12.3. For the past 2 days I’m having strange experience with my network. It says no service. 2 days before it says no service at some times and automatically connected to network later. Then again says no service and automatically connected again. This happened repeatedly.
But yesterday onwards it keeps displaying no service. More interestingly from today morning onwards, it keeps on searching and not even showing no service... it’s so strange experience.
Please don’t suggest any typical repair options like restart the phone, or remove Sim and insert again, or reset the network setting etc all... I have tried everything, it still not working...
I have removed my Sim (Airtel) and tried with another mobile( Lenovo). It works well and good. But on iPhone it’s not working. I even tried inserting my cousins Sim (Vodafone) and it also not working. It proves that there is no issues with carrier also...
some one please suggest me any possible ideas (my head is gonna blow away cause I have been using iPhone family for the past 12 years with not a single issue)
when I go to settings - mobile data - it is empty white screen with no options...
additional information, I updated to iOS 12.3 just 2 days before. Could it be a problem?
iPhone 6, iOS 12
