HI If you are asking for pin number contact your service provider , he will give you a default pin . If you try pin more than few predefined no of times your phone will ask PUK code which can also be given only by your service provider which is specific for each and every mobile number . Donot try PUK code many times or else your sim will be blocked and you will need a new sim.
Contact your sim customer care department over phone.

There will be a security check to know whether you are the owner of that sim so noone can unlock it without owners information.

I have a t-mobile phone but a cingular smart card...


If the Cingular SIM card won't operate the T-mobile phone now? You'll have to have the phone "Unlocked" for it to work with your ATT/Cingular SIM Card. Some local Cell Phone Shops may provide unlocking services for a nominal fee (you'll have to call around and ask), or you can send it out to be unlocked as this service can be found by searching online, as you can see here: http://www.google.com/search?hl=en&q=cell+phone+unlocking&btnG=Google+Search

Unlock my blackberry 7290


Like you being with T-mobile, I bought a cingular phone off ebay that wasn't unlock. My sims didn't work either. My network just said call Cingular which is now AT&T and they gave me the MEP code to unlock it. Beware, you need to confirm all of your information from your network before they will help you.

Unlocking a cingular razor for t-mobile


Your safest bet is to contact cingular for an unlock code. THere are also tons websites that are out there for unlock codes, most require payment.
Be careful if you use a website however... If the wrong unlock code is entered too many times the phone will be permanently locked to tmobile
