Hi,

I'm Ben and -- hopefully -- I can provide some meaningful

assistance.

It seems that your SIM card is locked.

SIM CARD:

If you enter a wrong PIN code too many times, usually three,

your SIM will lock itself. This protects you from someone using

your personal information or making calls if your cell phone is

lost or stolen. You may see "PIN blocked" or Enter PUK code" on

your cell phone display. The PUK code stands for PIN Unblocking

Key. In the U.S., the PUK code is rarely provided when you get

your subscription.

If you do not have your PUK code, contact the Customer Care

customer again. Give them your phone number and once they

are sure it is really you, they will give you the PUK code.
You will then be asked to set a new PIN code. Once you have

your PUK be sure to keep it in a safe place.

Note that if you enter a wrong PUK 10 times in a row, the SIM

will be permanently blocked, and you'll need to purchase a new

SIM card.
