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 ,and unlock it yourself using unlocking instructions which is given in the site itself.

Unfortunately you will need to go the AT&T store or call AT&T customer service, your SIM card got corrupt and you will need to have it replaced, good news at least it wont cost you anything.

2. Buy a new sim card.
If this does not work, then check to see if it is unlocked.

It's means your phone still locked for particular network, you must unlock it with blackberry pearl 8100 unlock code. To get blackberry unlock code you can purchase from third party sites on internet, please remember don't try to use free unlock code since it's can damaged your phone.

Whenever i turn on my Pantech Matrix, it says Invalid card, and shows a picture of a SIM card or something with an arrow pointing down.

Check to see if you SIM card is inserted correctly or if its loose. If that doesn't work you will unfortunately have to get a new SIM card. They run, I think, about 20 bucks.
