How to Unlock Three Phone (iPhone/Android) to Any Network Free

Three is one of the fastest-growing mobile networks globally, providing fast, reliable service to more than 130 million users across Hong Kong, Macau, Indonesia, Austria, Denmark, Ireland, Sweden, and the U.K.

Even so, not everyone is keen on the limitations that come with having Three as their sole carrier. What do you do if you want to switch networks, but you’re using a device that’s locked to Three’s network?

Just unlock the phone using one of the following easy-peasy procedures, both of which can be completed in a matter of minutes.

The unlocking procedures are different for different countries, I’ll talk about them separately.

Part 1. How to Unlock a Three Phone (for UK Users)

In this section, I’ll show you the information about Three UK Phone unlock.

Check to See if Your Three Phone Is Already Unlocked

Smartphones are powered by tiny computer chips known as SIM cards. When activated, SIM cards allow mobile device users to connect to the internet, send texts, make phone calls, Facetime with friends, watch cat videos, and avail themselves of the various other privileges of living in the Digital Age.

SIM cards are linked to the networks of the providers that issue them. In other words, changing networks is usually as simple as changing SIM cards.

So, just insert a SIM card from another carrier into your phone to say if a message saying “SIM not Supported” or “SIM Invalid”. If so, your phone is locked.

However, what if you bought your device directly from Three? Does the same rule still apply?

Will Three unlock my phone? You bet. Three’s website contains a statement explaining that if you purchased a device from the company anytime after January 1st, 2014, it will already be unlocked and eligible for use on other networks.

That means all you have to do is replace your current SIM card with a new one, and you’re good to go with no mail-ins, jailbreaking, or obscure tech voodoo necessary.

Filling Out a Device Unlock Form

If you bought your Three phone before 2014, worry not. There’s still a way to unlock your device and make it compatible with a SIM card from another network.

Luckily for you, it’s not much more complicated than knowing your name.

Step 1. On the Support section of Three’s website, you’ll find a device unlock form explicitly meant to assist users with the problem you’re now having.

Step 2. Simply put in your personal info, phone number, email address, and the IMEI number for your device.

Step 3. Within 72 hours of the moment you hit “submit,” the company will send you a special Three unlock code, along with instructions for putting it to use.

Entering the Three phone unlock code will enable you to break the chains binding your device to the carrier and free you to explore different networks.

So, how to use the Three phone unlock code? It’s simple!

  1. Insert a SIM card from another network in to your phone
  2. Enter the Three Unlock Code
  3. Restart your phone to complete the unlock process

In some cases, it can take up to 15 days to receive your unlock code. Longer wait times are usually due to the network provider waiting to get a unique code from the device manufacturer. Be patient.

Things to Note

For non-Apple devices, here are two things you should know before sending an unlock request:

  • You must have a Three account to get your device unlocked. If you don’t have, you’ll have to purchase a Three SIM card online or from a local store. Then use the account details to complete the unlock form.
  • When completing the unlock form, you need to make sure the details of the account owner match up exactly to the info on your bill.
  • Three can’t help you unlock a blacklisted (reported as stolen or lost) phone

What the Heck Is an IMEI Number?

An IMEI (short for International Mobile Equipment Identity) number is a unique 15-digit numeric sequence used to identify your device.

If, like most people, you have no clue what your IMEI number is (it would be weird if you did), type *#06#* on your phone’s keypad to generate a pop-up displaying your phone’s IMEI number.

You can also lookup your IMEI number manually by navigating to Settings > About Device > Status > IMEI Information on specific devices.

  • I inherited my son’s out of contract Three Samsung S9. We factory reset it and I thought I’d be able to just put my O2 sim into it but it said sim not recognised. I went to a Three shop and they couldn’t understand it, insisting it was unlocked. To prove a point, in the shop, we tried my O2 sim, didn’t work. We tried my husbands Three sim, worked straight away. They couldn’t help. So I got a Three PAYG sim, registered an account and sent off the unlocking form. I’ve heard nothing and that was 3 months ago. HELP! I don’t want to move to Three because frankly their network coverage in my area isn’t great plus I shouldn’t have to!
