How To Unlock a Samsung SGH-D500 Mobile Phone Sim Free / All Networks

So what exactly does a network lock mean?

If your Samsung D500 is branded by a mobile network, they will place a sim lock on the mobile phone from the factory to prevent people using other sim cards that are from different network providers. You will also see network branding and logos in the phones menu and on the housing, especially with the 'Orange' branded version. Network providers do this is so it limits you switching to cheaper network providers, while using the same phone. Usually, if you ring up the customer service department, for a small fee, they will issue you with a unlock code to make your Samsung D500 sim free. But nobody wants to pay these days because a free unlocking method is available. So why not give it a try and see if it works for you?

Unlocking Instructions (Tested on Orange, T-mobile, 02 & Vodafone branded D500s)

1) Remove the battery from the mobile phone. This is by turning the mobile phone upside down and pressing the tab button at the top, to release the battery pack.

2) Remove the inserted sim card from the mobile phone. This is by using your thumb to push it upwards.

3) Reattach the battery pack and hold down the red color 'Telephone Key' for a few seconds to switch it on.

4) Slide the phone up, so you can access the dialer/number keypad and enter the following secret unlock code into the device '#*7337#'. Once entered, the D500 will automatically reset itself, during this process it will remove the sim card restriction and it will be fully unlocked. Now you can insert any sim card of your choice and use it with your D500 without having any issues.
