Need a phonelock for my cellular

yes surely you can unlock your samsung mobile but at a free of cost is not possible for this mobile so get a code at a reasonable cost itself........
With the help of the codes you can unlock your mobile, get the unlock code for your samsung SGH-G800 model mobile from this site Simpleunlocking.com , here get the best instructions and methods for getting the unlock code for your mobile.....

Which network operator do u have?
Try..to enter any number.........until it shows pin blocked

then it it Show "ENTER PUK" But dont enter Any thing wrong or it will lock ur sim
Then try calling on the customer care number with same operator by some one else cell......
keep browsing until u hear.. "PUK sim lock" Then it will ask ur cell number Enter It it will tell u the PUK and ur done

there are many ways to unlock your phone, the best and the easiest way i would suggest is by using codes , try unlocking using unlock codes from http://www.superunlockcodes.com/

the unlock code that u have entred didnt match n has corupted ur phones software .u need to visit any nearby Samsung authorised service centre and ask the to upgrade ur phones software and once its done ur phone will function as before

This is against Samsung and T-Mobile terms of service and is technically illegal. We are not able to help you on this site.

call your service company (i.e. sprint tmobile, altell.) they can provide you with a code or they might be able to get you a whole new phone... tmobile has done both for me….
Please rate my solution I need feedback J thanks
