Hi babybanchi,

Have a nice day.

Invalid Sim usually occurs when the mobile is locked to a particular network.To solve this you should unlock your mobile using software,cable and codes.Unlocking mobile using codes seems to be simple compared to other ways because it saves our time and money. There are numerous online sites that caters unlocking codes.

You can run this link for further understading:http://www.onlinegsmunlock.com/motorola-

Your PUK is listed on your account. You can call your customer service and they should be glad to provide that for you.

AT&T allows you to check that yourself if you log into your account online.

It's a rather long number so make sure you can see it clearly, or write it down before you sit down to type it in. NOTE: You only have 10 attempts to enter the PUK before it will lock your SIM permanently and you'll need to purchase another SIM to replace it.

Before trying the PUK (which is a PIN Unblocking Key), power your phone off and then back on. Then enter the PUK. Once you enter the correct code it'll ask you to enter a NEW PIN. Remember that one as that will be your new PIN.

If you get it wrong enough times it'll go to the PUK again.

Remove the SIM card and re start the BB with new SIM card.
Your sim card is not proper fitted . check the sim setup
