Question: can unlocked iphone be used on verizon?
Answer: Verizon runs on CDMA technology and is not compatible with GSM technology (T-Mobile & AT&T). ... Typically these phones will only operate on their own network. However, as long as your device is unlocked and has previously run on the Verizon network, your iPhone model 4, 4s, and 5 will work on the Verizon network.
