We thank you so much for joining us and we welcome you to the family. Making sure you can get your phone activated is essential and we are here to help. To confirm, did you receive a new SIM card for your iPhone X or were you attempting to activate the device on our network with your AT&T SIM card? We want to make sure that you have an actual Verizon Wireless SIM card installed in the device before we can assist with activating the device.
I have this same issue. I am in the process of switching from ATT and that response did not answer the actual original question. Yes, I am using the SIM card verizon sent me. I am still having the same issue, so what is the solution?
