For guaranteed success when attempting to unlock the Samsung i9000 Galaxy S, first it’s necessary to either find yourself a reputable mobile unlocking service or call your carrier. The latter is more expensive, but it’s the safest option as it’s approved by the manufacturers and networks and so won’t invalidate your warranty.
However, all those most now supply codes, not all carriers are too keen on giving them out to you as they want to keep your business. In the UK, you can only get an unlock code from your network if you’re a PAYG customer or if your handset is over 12 months old.
If you want to use a remote cell unlock service, then it’s as well to do your homework first via cell unlock forums, review sites and eBay. Do not, under any circumstances, accept a free code from anyone as nine times out of ten these will not work. If you input an unlock code more than three times your phone will be hard locked, rendering it useless to you.
Once you have settled on a supplier, making sure that they have contact details in the event of a problem and offer a full, money-back guarantee, then you need to find your Samsung Galaxy’s IMEI number. This can be done by entering *#06# into your cell’s keypad and the IMEI will then be displayed on the screen.
Write down the number, which should be between 15-17 digits, making absolutely sure you get it right, as an incorrect IMEI will result in the wrong code. Once you have done this, give the IMEI, along with your country and network to the mobile unlock supplier. They will then provide you with an unlock code as well as full instructions on how to carry out the unlocking process, which should be as below.
- Power off mobile and insert an unaccepted SIM
- Power back on and you should be prompted for you code
- Enter the code, reboot the phone and it should now be unlocked
If you get the error ‘no valid simcard’, take out the unaccepted SIM and perform the following:
- Type in #7465625*638*UNLOCK CODE# (unlock code is the number sent by your supplier
This should return the message ‘phone deactivated’ and your mobile will be SIM unlocked. If this doesn’t work then contact your supplier immediately and explain that the unlock code doesn’t work, they should be able to work out the problem easily enough for you.
That’s all you need to do; mobile unlocking isn’t the complicated mystery that many people seem to think it is these days and there are plenty of good suppliers to be found online. Another resource worth considering is to try your local mobile repair shop as these often provide a mobile unlocking service too.
