Hi everyone, verizon has previously unlocked my 9530 and just recently I performed the option handheld wipe option.

Q1. Do I need to unlock this 9530 again by VZ?
Q2. For my 9530 phone that VZ unlocked, can I simply insert ATT Simcard and start using ATT service?

thanks everyone.

Hi there. Unlocked one time, unlocked forever. You don't need to unlock again. You can always confirm that by going to options > advanced options > SIM card > show keyboard > type MEPD. If it's unlocked everything will show disabled and the network will show inactive.

Great.. Thanks for your quick response.

Q1. I just inserted my ATT simcard and I couldn't make call. Do I need to do something so that my BB with my ATT simcard?

Q2. While using ATT service, can I interchange phone by swapping simcard?

I got it.. just go into network setup and pick GSM network.
Save and screen is showing ATT.
