Guide to Fixing iPhone 6 SIM Card Recognition Issue

Restart Your Device

Reset Default Network Settings

Resetting the network settings is also a method that many people have tried and succeeded with. To do this, go to Settings -> General -> Reset -> Reset Network Settings.

Afterwards, wait a few minutes for your iPhone to reset and return to default network settings. In case your iPhone 6 still shows 'No Service' after resetting the device, you can opt for 'Reset all Settings'. Remember to back up all your data before performing this action.

Restart 3G

You can try toggling the mobile data to see if it works. Here's how: Go to Settings -> General -> Mobile Data -> switch from On to Off and wait. If there's still no signal, restart your phone.

Above are the methods to troubleshoot and fix the iPhone 6 SIM card recognition issue. These are approaches that most users can utilize to resolve the problem.
