said by 78036364:yes take your at&t phone and try using it on Verizon. At&t phones don't have CMDA radios in them which is Verizon uses for things like calling and texting. and the LTE at&t has is on different frequencies than Verizon. So as long as you don't mind not being able to call or text or use data sure take your unlocked phone over. Or you could just sell that phone and take those funds and get a phone DESIGNED for the network it's going to be on.
Not pointless. Many of us travel internationally, but because our phones are locked, we are unable to take advantage of the local rates in the countries we are visiting by using a local carriers sim card.
The wireless carriers know this, which is why they refuse to allow us to easily unlock our phones, forcing us to use their exorbitant international calling plans.
