Unlock a Samsung Galaxy phone

If you’d like to use your Samsung Galaxy phone on a different mobile network, you’ll most likely need to unlock it first. This free guide helps you to unlock a Samsung Galaxy handset from any networks in the UK and further afield.

If you got your Samsung Galaxy phone in the UK, either from a Pay-Monthly contract or with a Pay-As-You-Go sim card, it will probably be locked to that mobile network.

Unlocking your Samsung phone, or in fact, unlocking any Android smartphone, is required if you want to use it on a cheaper mobile network, or if when are abroad on holiday and want to save a lot of money by using a local SIM card. When you’re finished your contract and want a new phone, you can get it unlocked before giving it to friends or family. You can also unlock your Samsung Galaxy smartphone to boost its resale value on eBay and other websites.

In this free guide, we’ll take you through the process of unlocking a Galaxy phone one step at a time. We’ll show you how to check if it is actually locked, how to find the IMEI number of your phone and then we’ll take you through each of the UK’s major phone networks and give you the best methods of unlocking. In most cases you’ll want to get your phone network to unlock the phone for you, but in cases where they wont, for example if you bought the phone from someone on eBay, we’ll show you a simple way to get your Samsung phone unlocked.

Benefits of Unlocking

People often ask why phones are locked. The simple reason is that if a phone is locked to one network, it is likely that person will stay on that network for the lifetime of that phone, and probably longer because they get seduced by the upgrades. But by unlocking your Samsung Galaxy you can choose to switch networks and save quite a bit of cash. You can also delay your upgrade cycle by 6 or 12 months and move to a SIM only deal. With a Sim Only deal you will pay much less than a standard contract and get exactly the same number of minutes and get the same amount of data.

There are 3 reasons why you would want to unlock your Samsung Galaxy Smartphone. You can switch to a cheaper network provided your contract is over. You can use a local sim card while abroad and save on roaming costs. And your phone will be worth more money when you come to sell it becuase it is unlocked.

Is it legal to unlock a Samsung phone?

In the EU it is perfectly legal to unlock your smartphone. All of the UK networks offer a method of unlocking, although some make you jump through a lot of hoops. There are also some third party companies who have organised deals with the networks so that they can also unlock a Samsung phone without making it difficult. Remember that although we talk about Samsung Galaxy phones, any Android smartphone can be unlocked using these methods. If you want to unlock an iPhone you can also do that.

For some older Samsung Galaxy phones, there are some unofficial methods through which you might be able to unlock them. This generally involves installing some unofficial software on your phone. With so much malware and viruses on Android, I would really recommend that you avoid these methods. It might seem like it’s a free option but can you imagine having malware on your phone, which could get information about your contacts, your emails and the calls that you’ve made?

Step-by-Step Guide To Unlocking

It’s literally as simple as 1-2-3 to unlock your Samsung phone. Check if it is actually locked, send your IMEI number to ExpressUnlocks and then use your phone on whatever network you want.

How to check if your Samsung Galaxy is already locked

The easiest way to check whether your Samsung Galaxy is locked is to put a different SIM card into it and see what happens. Generally there’s 2 things that can happen. It will either show you the new network name or else it will give an error such as "Invalid SIM" The problem with this method though is that some networks "piggy-back" on a major UK network. Typically smaller networks like Giff-Gaff, or Tesco will use a Major network’s infrastructure. So a Giff-Gaff sim will normally work on an O2 phone. So that doesn’t really tell you if it is locked or not. SIM Cards are cheap now though, so you could order multiple from different networks and check them all.

How to find your IMEI number

In order to get your Samsung phone unlocked you will need the IMEI number from your phone. The IMEI number is a 15-digit number that starts with 35 for a Samsung Galaxy smartphone. It’s unique to your handset and will allow the unlocking company to set the unlock code directly to your phone.

There are two methods of getting the IMEI number on your Samsung phone:

  1. Load the Settings application. On your phone, navigate to Settings > More… > About device > Status. The IMEI number should be about half-way down in the list. But you know how they like to change the way the apps work. Just scroll through all the lines. Take a careful note of your IMEI number.
  2. Another way of getting your IMEI number is to open your phone’s dialler (just as if you were going to make a call). Dial *#06# (star hash zero six hash). Your phone’s IMEI number should pop up in a new window. You only need the first 15 digits of the number shown (igno re the slash and any numbers that follow it).

Unlocking Instructions By Network

Vodafone

The cheapest way to unlock your phone is to go direct to the network. Unfortunately though it’s also the method which causes the most problems. We have had a lot of feedback from people who have had to wait weeks for Vodafone to unlock their Samsung phone. They also have very strict restrictions over which phones they will unlock. You must have had your contract for at least 6 months but it must also be active. So if your contract has finished, it resets back to 0 and you need to sign up for another 6 months before they will unlock your phone!

For the majority of people it is better to use ExpressUnlocks because they will unlock your Vodafone Samsung phone no matter how long you have had it. They don’t ask if it’s in contract or not. They just unlock it.

O2

For some O2 customers it can be very easy to unlock their Samsung phone. If you are a Pay Monthly customer, who got their phone from O2, and you are still in your contract, you can normally get your Samsung phone unlocked for free. You do need to provide security information about your account and the IMEI number but after about a week it should be unlocked.

If you are a Pay as you go customer, or if you didn’t get the Samsung phone from O2, or even if your contract has finished, they are not so helpful. In those cases you will normally find it easier to use ExpressUnlocks because they can unlock any Samsung phone on O2 without needing any security information.

"Free" Unlocking Methods

It used to be that with older Samsung Galaxy phones (Normally the Galaxy S3 and older) it was quite easy to unlock your phone for free. You could "root" your phone then run a special app to generate an unlock code. Just a few years ago this was a reasonably safe thing to do with your phone. But now, it leads to a number of issues.

The least of which is that Samsung software, since 2012, regularily checks whether the handset is running an official version of their software and will lock the phone again. Worse than this though is that just like Jail-Breaking on iOS devices, the whole industry behin rooting phones or Jail-breaking, has been taken over by organised criminals who want to install mal-ware on your handset. When you root your phone you are bypassing any security that Samsung has put on your phone and you’re effectively allowing apps to have free access to all parts of your phone, including text messages, contact information and maybe even passwords. So it’s really not worth it. I would recommend that you pay the small amount to get your Samsung Galaxy phone unlocked properly and keep the official Samsung software on there.
