Unlock Codes for GSM cell phones

This guide will walk you through unlocking the Samsung Hercules, the recently confirmed Samsung Galaxy S II headed to T-Mobile.  As usual included in the guide are some links to reviews and speculation on specs and even some leaked pics.  T-Mobile will hold a press event at the end of August to announce the phone, so stay tuned for more details.

As with any unlock code, it’s dependent upon your IMEI so you’ll need to know what your IMEI is before you begin on any unlocking journey.  The IMEI can be found by typing *#06* on the Samsung Hercules keypad, or in most cases you can find your IMEI listed on a sticker underneath the battery.  Your IMEI will be the first 15 digits.

Once you’ve located your IME, you’re ready to unlock your phone and wont need a cable or any software to do it.  It’s usually pretty hard to get unlock codes for new phones from the carrier, so you may end up having to purchase one.  If you do, try the two sites linked to in the box at the top of the right column.  We’ll also link to a couple sources below in the unlock guide.

Coming soon to T-Mobile:  Nokia Astound.  Current specs on the Astound show it’s going to work on the GSM 850, 900, 1800 and 1900 bands making it an ideal candidate to unlock.  Unlocking the T-Mobile Nokia Astound will allow you to use almost any SIM or carrier in the US and across the world.  T-Mobile will sim lock the phone to their network, so you’ll want to contact them for your unlock code.  Contacting the carrier the device is locked to is always the easiest way to get your unlock code.  Unfortunately many carriers are reluctant to give you the unlock code unless your account is in good standing and you tell them you’re going over seas or give them another reason that you need to unlock your device.

To unlock the Astound you’ll need to get your code from T-Mobile or a source for unlock codes on the net like UnlockCellPhoneCode.com.    Your unlock code will be specific to your phone and your phones IMEI.  You can get the IMEI of your device by typing *#06# on your Astound keypad.  You will need to give your IMEI to T-Mobile or to an unlock service in order to get your IMEI unlock code.  Once you have your code you’ll need to know how to enter it and lift the sim lock T-Mobile placed on your phone.

1. Power ON your Nokia mobile phone without your SIM card.
2. Now type: #PW+CODE+1# (Where CODE is your Nokia unlock code)
3. Your phone should now show “SIM Restriction Off” and is unlocked.
