Buy a T-Mobile SIM card with prepaid, or a plan. You won't need Straight Talk. You can't use Straight Talk on a GSM phone (with a SIM) because I believe Straight Talk is a CDMA (no sim) type service.How do you use a tmobile sims card in a unlocked blackberrycurve?
Hello.

Buy Blackberry curve from any where.you can unlock your Blackberry by simply enter unlock code through keypad and can use it with any GSM Network worldwide.

Unlock code generate on the basis of IMEI#.

You can get IMEI number BY:

Pressing *#06#

Or Options -%26gt; Status

Or look underneath the battery.

You can get unlock code at cheapest rate.

Hi,

It is simple to use sim card in an unlocked Blackberry.

Remove back cover,take out Blackberry battery,a sim slot for sim insertion seen clearly in it.just put sim card in it and turn on your Blackberry.
