Need another unlock after install Rogers?

Hi,

I've unlocked my 920 through at&t, but after I installed Rogers on the phone, it doesn't seem to work when my mom brought it to China. Is another unlock needed?

No, once you unlock your phone, it stays that way even if you change the phone ROM. Maybe you need to check the SIM card.

Thanks for reply. What could go wrong with the sim card?
