Unable to activate - error.
Trying to set up this iPhone 6s and I keep on getting this message.
Unable to Activate
An update is required to activate your iPhone.
I have put it into restore mode twice now into iTunes on my Mac and attempted to Update & Restore. Still coming back with the same thing. Haven’t tried just restoring but it’s saying it needs an update. Also has the small exclamation mark in the top left hand corner with a “No Service” sign next to it, even though it has a SIM in it.
Any help would be much appreciated.
