SOURCE: SIM card not valid
Hi thee, I list here the possible reasons for "Sim card not valid"
1 - The phone is locked to a different network. In this case the phone usually accept the sim card the same , and has no network, but sometimes it may return the error message. Unlock the phone at a local shop.
2 - the SIM card is faulty. Test the card on a different phone to find out.
3 - The phone is faulty. Test the phone with different Sim cards, if the Phone returns same error on all cards, then the phone is faulty.

If u have entered a wrong PUK no. less than 10 times, then u can contact customer care and get the PUK unblocking code (its free). Remember each sim card has a different unblocking no.
If you have entered wrong PUK no. 10 times or more, then this SIM card is blocked and will have to be replaced by a new one. You need to visit any airtel franchisee, purchase a new sim, and they will delete your old sim card details and add the details of new sim card into their system. A new sim probably costs around 245/- (i think, though don't remember when i purchased it last). You need to carry old sim card + ID proof + any airtel bill (if postpaid, may get required).
If your connection had been a Postpaid with regular payment history, I would have applied a different approach

If you log onto your companys website under your account and go to the option that says devices you can get the puk code- If you enter in too many numbers it will permanently block your sim card and you will have to buy a new sim card from your cell phone company- they are about $20
