When you a buy a new mobile phone, the chances are it will come with a network block applied. This is set in place by the network that operates your phone, and it prevents you from using your handset with any other network’s SIM card. The reason behind this is evident: The company wants you to stay with its network. Despite those efforts, you are completely within your rights to change your network, and you can remove the block by finding your unlock code. This process is the same on most mobile phones.

Unlock Phone for Free With IMEI Number

Find your phone’s IMEI number. This is often colloquially referred to as a “serial number,” and is a unique 15-digit number which is found on the label underneath your phone’s battery. You can also find this by typing “*#06#” into your handset. This is one of the many codes that performs operations on your phone, and is used in the same way as the unlock code you’ll receive later. Copy your IMEI number down onto a piece of paper.

You can also find your IMEI on your original phone box, on your SIM card tray or in "Settings," according to

Contact your network. Most networks will provide you with your unlock code in exchange for an often relatively large fee. If you have been with them for a while, they may be merciful, and give you the code for free, but in most cases they will charge. MoneySavingExpert points out that this is more likely if you've had a contract for a long time.

Give them your IMEI number. This is needed to generate your unique unlock network code and is the only information they will require besides the make and model of your phone. Networks are generally quite slow in sending out your code, and you may be waiting around a week to receive it.

Type your unlock code into your handset. This can normally be done without special preparation, but some phones require you to switch it on without the SIM in to remove the network block. You will see a message confirming that the block has been lifted.

Network Unlock Through Independent Companies

Get your phone’s IMEI number in the way described above (type “*#06#” into the handset). Many mobile phone users need their phone unlocked at some point, and as a result, there are many companies online, such as DoctorSIM, that provide unlock code for a small fee.

Enter details of your make and model into the website, and quote your IMEI number in the space requested. Websites often charge a lot less and deliver a lot more quickly than the networks themselves, and are in many ways the better option. You will usually have your code within a few days.

Input the unlock code into your handset. Your phone will now be free from the network block, and you can change networks. Unlocking also increases the resale value of your phone.


Unlocking your phone for free is more difficult. The online mobile phone community is very good, but it isn’t likely you’ll find a code that works on a forum. They are worth trying if you can’t afford a more official method, but reports of success are rare. The same can also be said of unlocking software, it is definitely hit and miss, but worth trying if you’re on a budget.


As with any big online business, there is a small minority of scam websites, so stay alert. If something doesn’t sit right with you, it is better to use a more reputable site.
