Phone recognises Sim Card, sees number but says "No Service"
So I've received an iPhone 6s which was water damaged.
After having had it through the ultrasonic cleaner I turned it on and it all worked, at least that's what I thought.
The issue is that the phone recognises the sim card inside, shows me the phone number in iTunes and even tells me that I've inserted a wrong sim (its locked).
But after inserting a sim card it goes to "Searching" and then within a couple of seconds goes to "No Service".
I've replaced the antenna on the device and still nothing.
Any advice would be greatly appreciated!
Is this a good question?
