I am upgrading my current Moto X (Gen 1) phone to a Pixel. Will my Moto X sim card work or do I need to purchase a new sim card?
No, it will not. The sim card in CDMA phones operates differently than those in GSM phones, which on RW, your Pixel will operate on the GSM network at this time.
Since I am currently a Republic Wireless customer, will Republic send me a sim card or do I need to purchase one?
That GSM carrier is TMobile. So make sure TMobile’s network works for you by entering your address in the coverage checker. Note that a fair signal will probably mean you will have issues with cellular calls.
You will need to buy one. You can purchase them from either Amazon or Republic Wireless.
If I buy the phone through Project Fi, will that sim card work with the Republic network?
