How do I switch from a locked Z10 on AT&T to an unlocked Z30?

i have a locked Z10 on ATT in the US. I bought a unlocked z30. How do I switch phones without involving ATT?

Just switch your sim card. That's it.

You may have to register youe imei # with them though...

Thanks! When I switch the sim to the unlocked Z30 will I loose anything ?

Well you will have to transfer all your data from the Z10 to the Z30. You can do that via device switch in Link, or restore a backup from your Z10.
