That will work as long as both devices use the same SIM card type and the service requirements were met on the sales agreement for the prepaid phone you want to use so that it would be unlocked for use on postpaid accounts.
GREFOR62, making sure you have the right SIM card for your device is a must. Allow us to go over the details. Just to clarify, are you looking to use the Pre-paid device on your post paid account? If so, you will need to activate the prepaid device first along with purchasing 1 month of service with Prepaid. Once that Pre-paid device is activated it will be eligible to use on your post paid account. Please contact our prepaid department to get started 888-294-6804. Does this help clarify your concern?
