iPhone 7 "No Service" Issues

Unfortunately I own iPhone 7 (model number A1660) with very rare “No service” issue and

because of that it is unusable. Until now it was working just fine. I am disappointed

that this happened to me and it’s not even my fault. But apparently I missed the four year period of free service so there is nothing they can do to help me.

Did it happen to somebody else and did you get any help at all?
