If I have a Moto X phone from my provider now do I have to bye your phone to switch over to republic?
The Moto X (1st Gen) and the Moto X (2nd Gen) have a modified operating system and are unique to RW’s service. If your Moto X was used with a different carrier then it will not work with Republic Wireless. You could sell your Moto X on eBay and buy the Republic Wireless version of it there too.
The Phones you see in the Phones section (take link at the top of this page) can be purchased from RW or any other seller. If you buy one elsewhere you also have to buy a SIM card for it and you have to be certain the phone you are buying is the exact model as listed in the BYOD section of the Phones page.
