My3 Account

What is My3?

Your My3 account is your first port of call for any account updates or changes on Three, so it’s worth knowing the ins and outs of what you can do with it and how you can access it.

There’s a lot to take in, from managing your bill, to changing your personal details, using the app, and even just getting an account set up.

Below we’ll explain all the key aspects of both the My3 website and the Three app. Note however that we’re not part of Three, and that while the information below was accurate at the time of writing (January 2024) it could change at any time.

How do I register My3 account?

If you’re a Three customer then registering is easy. Just enter your phone or device number on this registration page and if it’s a valid Three number you’ll be texted a password for the service. Once you’re in you’ll be free to change the password to something more memorable.

How do I login to My3 account?

Login to My3 Account

My3 is designed to be as easy to access as possible, wherever you are and whatever device you’re using.

From a computer you can simply login here with your mobile number and password, while from a smartphone you can make use of the handy Three app (available for both iOS and Android). Just download it onto your Three phone and you’re good to go.

If neither of those options are convenient then for most account queries you can always call on 333 from your Three phone or on 0333 338 1001 from any other handset. Or if it’s a mobile broadband account that you want to manage call 500 from your Three mobile or 0333 338 1003 from any other phone.

What can I do on My3 account?

My3 makes it quick and easy to manage your account. Whether you’re on Pay As You Go or Pay Monthly you can see your balance and allowances from My3, which shows what you’ve got left and when your allowances will reset.

Your remaining allowances are front and centre on the main screen of your My3 account, so they’re easy to find, and you can view your bill right above that.

My3 Allowances and Usage

You can also update your personal details from My3, view or print your most recent bill or any others in the last twelve months, check any spends made outside your allowance, register a credit or debit card, set up a direct debit or pay your bill.

In fact, you can do almost anything you might want to from your My3 account. Other things you can do include setting up or changing spending controls if you don’t want to spend too much money or spend money outside your allowances, purchase add-ons, turn off adult filter, change your marketing preferences, change your price plan (if eligible) and change your PIN or password.

Going abroad? Then you can purchase a roaming pass so you can use your allowances outside the UK (if this isn’t already included in your plan).

If you’re wondering when you can get your hands on a new phone or change your price plan you can check that too, as My3 allows you to see when you’re due an upgrade. Plus, as an existing customer you’ll often have access to exclusive offers, which can also be found through My3.

What type of accounts can I manage with My3?

My3 lets you manage any Pay Monthly or Pay As You Go SIM card, handset, tablet, dongle or mobile broadband device, so whatever device or service you have you can fully take control of it from My3 – as long as it’s on Three.

Why should I download the Three app?

The Three app gives you access to more or less all of your My3 account services on the move, wherever you are. All it needs is to be installed on your Three device and have mobile network access so it can confirm your account information.

My3 Allowances

Things you can do from the app include checking your balance and usage, checking when your allowances reset, seeing when you can upgrade and viewing exclusive offers.

My3 Billing

Plus you can buy add-ons, see your next bill date, view previous bills and edit your personal or payment details.

The app also has extra features, such as the ability to find the nearest Three store and check its opening times in case you’d rather speak to someone face to face.

My3 Contract Duration and Upgrade

You can also change your price plan direct from the app once every bill cycle if you’re on a contract, plus the app can send you to support pages for all sorts of issues, from network coverage and problems, to delivery support and plenty more besides, and even has a live chat function if you want to talk to a Three employee.

My3 Options

You can also quickly launch the Three+ rewards service from this app, and access Three Communities, for additional support.

Can I upgrade to a new handset from the Three app?

If you’re eligible to upgrade you can use the ‘upgrade’ option in the Three app. You can also upgrade by calling customer services on 333 from your Three phone, or 0333 338 1001 from any other phone.

What platforms is the Three app available for?

The app is available free to download on Android and iOS, so if you’re on any major smartphone platform you’re covered. Though if you’d prefer you can always log in to My3 through your phone’s browser anyway.

What if I can’t do what I want to do from My3?

My3 lets you deal with most account issues, and it’s clearly laid out, so things should be easy to find. It also offers help and support for other problems, such as replacing a SIM, but if you can’t find an option or answer from it you can always head to the full knowledge base here, which as well as in depth information and FAQ’s provides access to contact details.

If you’d rather speak to someone you can dial 333 from your Three handset or 0333 338 1001 from any other phone.

I’m having problems logging into My3

Logging into My3 should be as simple as entering your mobile number and password, so if your password isn’t being accepted double check that you’ve entered it right, complete with correct upper or lower case letters.

If you can’t see the login section of the website this could be solved by accessing the site in a private window, which is opened with Ctrl+Shift+N in Google Chrome and Microsoft Edge, or Ctrl+Shift+P in recent versions of Firefox.

If you’re still having issues full troubleshooting tips can be found here, or you can call Three on 333 from your Three handset. Note also that you can’t get full access to My3 from an iPad, due to its inability to receive texts.

If you’re trying to access My3 for the first time from a MiFi device you’ll need to connect your computer to the MiFi’s network, then head to http://3.home in your browser and click ‘Go to inbox’ to get your password.

If using a dongle, you’ll first need to plug it into your computer, then when it says ‘Ready to connect’ click ‘Connect’, followed by ‘Texts’ to get your password. If you aren’t given these options then instead navigate to http://3.home and click ‘Go to inbox’. If needed you can also find your Mobile Broadband device number at that URL.

To find the number on an Android tablet, head to the main Settings screen of your device, then tap ‘About tablet’ or ‘About device’, followed by ‘Status’ or ‘Phone identity’. Your number should then be listed under ‘MDN’ or ‘Phone number.’

On a Windows tablet, head to the Settings screen, then tap ‘Change PC settings’, then ‘Wireless’, then tap on the ‘3’ and your number should be listed next to ‘Mobile number.’
