When your iPhone connects to a Wi-Fi or Bluetooth device for the first time, it saves information about how to connect to that network or device. If something changes with that process, it may cause connectivity issues.

iPhone 8 plus has no service it doesn’t let me use my phone I have factory reset I have contacted my carrier the network works and the sim works in another iPhone

These are the most unhelpful and ineffective solutions to be found on the internet. The 8 & 8 Plus have Apple’s built-in hand grenade designed to take down phones so owners will replace them. Every model had one: on the iPhone 4 it was the WiFi chip. On the 5 it was the charging, and so on. On the 8/8 Plus it is the baseband chip causing 90% of no-service issues. Go to Settings and check if you have an IMEI number displayed. If you don’t, promptly bin your phone and change to Samsung.

It’s likely, but try a DFU Restore first before you go to get it fixed. You should do that to be absolutely sure it’s not a software issue. No need to spend money on repairs if it’s a software problem.

This also happens when the phone is locked or reported lost or stolen.
