If you had to replace the back housing I would think the iPhone took a bad hit and it would be quite likely the issue was already there before replacement and/or the handling of the board made the damage just evident. No service flag with request to update is typical of a hardware damage to the logic board where the processor can’t find the baseband. It could be due to a number of components and will require deep microsoldering skills to be fixed. The only thing you can try is a DFU restore, but there are serious risks it won’t complete and phone will be stuck in restore mode until fixed.

The SIM socket is located on the logic board as marked here in Purple

You need a SIM held within it to tell the radio what bands your cellular carrier uses and can identify your phone.

If your SIM socket is damaged and/or the cellular radio logic is damaged as well as the connections to the antenna units then you can encounter inability to connect to the network.

Breaking parts is always a bad sign. Post a clear picture showing the damage and leverage the pictures within the iFixit teardown iPhone 8 Plus Teardown to identify the broken part/s so we can see more clearly what you are facing post a marked up picture as well Adicionar imagens a uma pergunta já existente

Try these steps:

  • Turning off Wi-Fi calling and Voice LTE may fix the problem
  • Open Settings and tap Cellular -> Wi-Fi Calling. Turn off the switch next to Wi-Fi Calling on This iPhone to turn off Wi-Fi Calling and go to Settings -> Cellular and tap Cellular Data Options. Tap Enable LTE -> Data Only to turn off Voice LTE. You’ll know Voice LTE is off when the blue checkmark appears next to Data Only.
  • Turn Airplane Mode Off And Back On
  • Turn Cellular Data Off And Back On
  • Check For A Carrier Settings Update open Settings and tap About to check for a carrier settings update. If an update is available, a pop-up will appear within about ten seconds.
  • Eject your Sim Card and Turn off Your Phone Once the device has been powered down reinsert the SIM and then power the device back up.
  • Reset Your iPhone’s Network Settings
  • Put Your iPhone In DFU Mode
