Can a Motorola ROKR E1 from Cingular be put on a Verizon plan?
No, this phone cannot be used on Verizon's plans because the
phone is tied to Cingulars service and is a GSM phone, whereas
Verizon's network is CDMA, and cannot use the phone. Even if the
phone is "unlocked", it will not work on Verizon.
