Just received a new Moto X pure. Sim card was already insterted but phone is not recognizing it. On the republic wireless app it says “Great News your phone is supported- please insert your sim card”. I tried removing the sim and putting it in again but the same screen comes up.
Were you able to get this resolved? For what it’s worth, here is Motorola’s guidance for inserting the SIM: Insert or remove SIM and memory cards - Moto X Pure Edition.
You might also install this app: SIM Card Details - Android Apps on Google Play. Do you see a string of numbers for SerialNumber? To protect your privacy, please don’t share those numbers, just let us know if anything is there. Example below:
