If you have purchased blackberry curve 8330 from Telecommunication company then its not possible to change the Sim card as they are in build with phone. So, you need to purchase it without connection package, then only you can use it. Vicar.

Sometimes the simcards need to be activated by the provider. if this is the case u normally get a letter which provides u with information to activate the sim online!

There are no card slot for this phone because it use cdma technology and is attached only to one networke unlik GSM phones that use sim cards.

Take the back off and see the instruction of the way it is inserted. It has a graff to show the position on the sim.
