Hi chaso. If you are using a different phone, you would need to purchase our BYOP (Bring Your Own Phone) SIM. As long as it is an AT&T, T-Mobile compatible GSM phone or an unlocked domestic GSM phone, it will work with the BYOP (Bring Your Own Phone) Program. To view the program, please visit www.net10sim.com
. We are not able to transfer contact or any save files on your phone. As long as the phone number is active, we can transfer the phone number and your remaining service. Thanks.
