will apple fix my antenna for free even though my screen is cracked?
I have an Iphone 7 with a cracked screen, but recently my phone stop getting connection to a cellular network, it just says searching at the top
It sounds like more than the screen broke. You need to make a genius bar appointment and they will tell you what they can do. If there's more than the screen broken they will replace the phone for a flat fee. See: iPhone Service Pricing - Apple Support
