SIM not Supported? How to Unlock your iPhone for FREE
In this video I unlocked an iPhone 6S with iOS 10.3.3 14G60, the message "SIM not Supported" means the iPhone is locked to a carrier, to carrier unlock your iPhone please follow the instructions on my video.
I used the AT&T Portal to Unlocked my iPhone: https://www.att.com/deviceunlock/
If you are not in the USA, try to use a VPN like Proton VPN https://protonvpn.com
The message "Could not activate iPhone" Only means that the activation server cannot be reached, so it's a connection problem, it does not mean the iPhone is carrier locked.
