Hi PUK code is called as PERSONNAL UNBLOCKING KEY. Your phone will ask for PUK code when you entered the PIN code wrongly several times depending upon the mobile make. The mobile asks for PUK code so that unauthorized persons do not use your mobile for wrong cause. To get PUK code please contact your service provider through phone or go directly to their office. They will provide you the PUK code for your mobile. The PUK code for mobile phone.so that you can open your phone. When you planning to call your service provider you cannot use your mobile as it is fully locked. Please use some other mobile with same network to call your service provider.

If they are satisfied with your answers they will provide with the PUK code DONOT enter the PUK code several times wrongly,It will block your sim card permanently. This PUK code is FREE. You no need to pay any sum to get the PUK code Thank You.
That phone is a CDMA phone and does not use a SIM card. Sprint phones and Verizon phones are CDMA and do not use SIM cards. AT&T and T-Mobile use SIM cards, but are GSM phones, a whole different technology/signal. Nextel phones do have SIM cards, and some "World" phones at Verizon have SIM cards for traveling overseas where there is no CDMA, but your Samsung SPH-M220 has NO SIM card.
Just in case you want to check anyway, here is a link to the user's manual:
They sell these already unlocked on ebay by the hundreds. If you're attached to the one you have, you can find a cell phone store that will unlock it for you by visiting unlocktotalk.com to find a local store or send it in to unlocktotalk.com. They have a CDMA unlock mail-in service if there is not a local cell phone "flashing" store which provides this service in your area that can reprogram your phone to work with the new CDMA service of your choice.
I suggest you log on to www.unlocktotalk.com to get details. It only costs about $20 and it is 100% legal. They openly advertise that they can unlock CDMA cell phones (or GSM-in a separate section of their website- if you need them to.) You can do it at a local store or if you're sending it in, pay through PayPal and only pay if they get it done.
When you first start the device, it asks you to tap the screen to begin. Tap the screen, do not hit any of the buttons. If it does not work, I'm sorry to say it will most likely be the touchscreen. As wonderful as the i700 is, it's still delicate technology. The touchscreen is a horrible repair to undertake, unless of course you happen to find a replacement on ebay. Replacement services are around $169. Doing it yourself is easy enough, save finding the parts. Another unit from ebay is a good bet. That's what I did. The repair is simple enough. In fact, you can find a video on Google video that shows you how to remove the screen. Good luck.
