iPhone 8, A1905 No Service issue!
Hi! My iPhone 8 is acting up. I had full service a while a go, and suddenly it started to go down in the service bars, until the whole service bar area turned grey, but i still had 4g. When i tried to make a call i heard thee quick beeps and my service bar changed from no bars to no service. Tried to update carrier settings, reset network settings, take the sim card out and in and restore from backup. If i restore from backup, i would get full service as usual, but within a few settings it's back to No Service. Apple customer service ment it could be a hardware fault, but could it be fixable without returning the phone for a new one?
iPhone 8, iOS 11.2.6
