Definitely you can. The Sprint SIM that came along with your device should work with us under our CDMAS service.
In case the original SIM is no longer available, we are ready for that. Get a Red Pocket Mobile’s CDMAS SIM. Simply go to this link https://goredpocket.com/sim.html then select the type/size of SIM that you need.
For your convenience, CDMAS pre loaded SIM is also available. This will give you service on your first month.
