Will my Sim work in a Pearl?

Hi, I have the LG Shine (ATT) can I use my sim in a blackberry Pearl? What do they mean by unlocked? :)

Welcome to CB! If the Pearl is either an At&t phone or unlocked then yes. Carriers lock devices to only work with their network. They can be unlocked to work on all GSM networks with a code you can get from the carrier or third party unlocking services.

Yes you can. :)

Thank you!!! But, will I have to pay for internet? I don't need it.

:)Welcome to CB!!! Hope you find it helpful!:)

As for the internet...
If you want to receive E-mails you are going to have to get a data plan from your carrier. That automatically gives you internet.

If not and you just want to use SMS (text) and MMS (pic/video) then you don't need a data plan and therefore won't receive internet nor will you receive E-mails.

Hope that helps!
