SOURCE: Invalid Sim

If your phone is locked to your original sim card, you will not be able to use any other. contact your provider and see if it is in fact locked. Many phone providers lock their phones.

Invalid sim card

I think your mobile is locked to a particular network so that your Blackberry 6280 says invalid Sim when you put your Sim in it. Find your locked network and unlock it to use your mobile with your Sim. You can find your locked network by switch off and switch on your mobile. At the top of your mobile screen the logo of that locked network will be displayed. After finding your network unlock your mobile using unlock code. Get the code from the site Wickedunlock.com ,and unlock it yourself using unlocking instructions which is given in the site itself.
