Hi, It seems the sim card you are trying to use has a pin code and sim card pin code are usually any amount of digits you want to use for it. You can check if it's a new Simcard then on the pack of the Sim card you will see a pin 'on the pack. But if it's not anew Sim card,that means you will need to contact the Sim service provider for help to assist you by tell you what pin code to use.

Have a nice day.

The SIM card door is covered by a rubber casing that peels back. Pull back the rubber flap to access the SIM card door. The flap that needs to be pulled back is the top left corner of the Sidekick above the Menu key.

Insert the SIM card into the slot with the gold contacts facing up and the cut corner facing out. When you release the SIM card, make sure it is locked into position behind the catch so it does not spring out. Replace the bumper, and then turn on the device.

It appears that inserting the SIM into a Sidekick is a rather tricky process. If the above does not completely solve your problem, here is a link to more details on inserting the SIM card. http://support.t-mobile.com/knowbase/root/public/tm50134.htm?

put a valid sim in it and enter 1234 or 0000 and see if it opens

first remove the sim card and then switch on the phone... then choose antenna on... after a few seconds you will see emergancy only on your screen ... turn off your mobile and insert the sim and switch it on again ... this solved my problem ... but this is not working on my cell now.. does anybody have a solution?

the sim card goes on the bottom of the phone under the rubber thing (idk what to call it) you need to lift it up and you will see a pictuer of hoe to pu in your sim card and for the battery idk

you will need to contact your mobile provider and ahve them unblock your simcard.

A few things, the sim card is not seated fully , it's in the wrong way, or damaged . pressing buttons will have no affect on the card.
