An update is required to use cellular data on this phone
I have already updated my phone fully. Reset network settings and all of these things. Nothing is working. I saw that this is a common issue with iPhone 7 (I bought my phone from America) and it should be fixed for free. I currently live in Bahrain and they said that the branch here can’t fix it or compensate me in any way. I even contacted apple support and they said they can’t do anything from their side.
