We (usually) do not provide network unlock codes on FixYa. However, you can visit this website if you wish to SIM unlock your phone: (eBay) Simply scroll down until you see a listing for both your phone and your network carrier. http://shop.ebay.com/i.html?_nkw=samsung+a177+unlock+code&_sacat=0&_odkw=samsung+sgh-a177+unlock+code&_osacat=0&_trksid=p3286.c0.m270.l1313
Also, if you are requesting a security unlock code (forgotten PIN or PUC code for example) we refer our customers to their Cellular Service Provider's customer service dept. After verifying that you are the owner of the phone they can give you a master security code which you'll enter on your phone's keypad. This will security unlock it where you can use it again.

Hi

If you changed it and forgot the security code please contacts your device dealer. They will provide you the default security code so that you can use your phone.

This security lock prevents thieves from being able to make use of stolen handsets that is why it can only be unlocked by authorized device dealers.

Thank You

no, there is not hard unlock code. you have to reset the phone by the help of service center personnel. then u can change the code and remember by changing the default code.
