I am on the refund .5 plan using a MotoX(2). Can I keep my plan if I replace my faulty equipment?
If you desire to keep the same plan you would need to purchase a Republic Wireless compatible phone on the used market (all of the new phones would only be usable on 3.0 plans). eBay and Swappa are popular places to purchase used Republic Wireless phones compatible with the 1.0 or 2.0 plans (the phones you would be looking for would be Republic Wireless versions of the Moto E 1st and 2nd gen, Moto G 1st and 3rd gen, and Moto X 1st and 2nd gen). Buying tips can be found at Buying and Selling Used Republic Wireless Phones .
