Hello everyone. I have an issue regarding my Iphone 7plus bought in amazon. At first it was working fine the battery doesn’t drain fast and not using any sim card. but after inserting a sim card it was working and reading the sim card then after a couple of minutes it says no service and the sim card slot got hotter then after that the battery drains fast and until now even without sim card inserted. it all started after inserting a sim card. what seems the problem? Thank you!
It could be a few things and will defiantly be a board problem. · Baseband CPU fault due to an audio IC repair. (most likely) · Baseband PMU. · Sim holder. These are costly repairs and you should be asking for a refund.
