I’m so sorry to hear about your issue. I know that can be frustrating. Hopefully, we can get this resolved quickly. I understand you are getting a SIM card error.

1. Ensure sim card is inserted with sim contact facing the right way. Reverse the sim tray and insert. See if it connects.
2. Turn off LTE option in mobile network settings and see if it connects.
