Unlocking your phone gives you the freedom to use a SIM from any network. It makes it easier to switch to a cheaper deal, cut your monthly costs, or pass your phone on to someone else. If you are out of contract, your network will not charge you to unlock it. If you are still in contract or using pay as you go, there may be a small fee. This guide explains, step by step, how to remove the digital lock and start using your phone wherever you like.
Why unlock your phone?
Although networks are no longer allowed to sell locked phones, anything bought from a network before December 2021 is very likely to be locked. If you pop in a SIM from another network, it simply will not work until the lock is removed. Once your phone is unlocked, you can use any compatible SIM. The main benefits are:
Lower monthly costs
If you are happy with your phone but not your tariff, unlocking lets you switch to a cheaper SIM only deal without replacing your handset.
Higher resale value
Unlocked phones usually sell for more on marketplaces like eBay, because they appeal to buyers across all networks and even customers abroad.
Cheaper use abroad
Travelling is easier when your phone is unlocked because you can buy a local SIM and avoid expensive roaming charges.
Quick questions
Why did mobile companies lock phones in the first place?
It encouraged customers to stay on their network for longer. Networks also used it to protect subsidised handsets.
Is it legal to unlock my phone?
Yes. You are allowed to unlock your device, and networks must assist you if the phone belongs to you.
How to unlock your phone
Before you start, check whether unlocking is actually needed. Insert a SIM from a different network. If your phone is locked, you will see a message on the screen.
Smartphones
The simplest way is to contact your network. In many cases, unlocking is completely free.
If you are on a pay monthly plan and you have finished your minimum term, the network cannot charge you. Some networks will even unlock your phone during your contract without a fee. You may be asked to confirm the request once the process is complete.
If the network cannot help, you can use a third party unlocker, although prices vary.
Unlocking older or non-smartphones
Some older devices can be unlocked using free codes found online. Giffgaff’s Unlockapedia is a useful tool that lists free codes for many classic Nokia, LG, Panasonic and Siemens models.
To unlock your phone using a code, you will need:
Brand and model
Usually printed on the phone, box or paperwork.
The network
This is the network the phone is currently locked to.
The IMEI
This unique number identifies the device. To find it, dial *#06# and note down the number shown.
Sites will give you an unlocking code based on the details you provide. Examples include:
Nokia format: #pw+2746763089+1#
Other brands: *2767*637#
To use the code, insert a SIM from another network and enter the code when prompted. You normally have five attempts, so check the details carefully before submitting anything.
Entering the code
For some phones, you must use the star key to enter letters.
Press * three times quickly for a “p”, four times for a “w”, and twice for a “+”.
If the code works, you will see a message saying the lock has been removed.
What if I still cannot unlock it?
Your phone may need to be unlocked using a cable. You can:
Pay a local unlocking shop
Walking into a high street or market shop is often easier than sending your device away. Prices vary, and a bit of polite negotiation can go a long way.
Do it yourself
If you are confident with tech, you can buy a cable online and download the software needed. This method can be complex, so always research it properly before buying anything. Each phone model often requires a different cable or “clip”. If you only need it once, you can unlock your phone and then sell the clip afterwards.
