Network Coverage

You can use Three's coverage checker when you buy online to check coverage at your address. Check coverage before you buy for your home address, AND in your most frequented areas, like your work place or friend’s houses.

Three covers 98% of the UK population and also offers 4G Super-Voice spectrum which allows 4G signal to travel further into buildings. This means you can access the internet, make calls and send texts in places never previously possible. Three covers up to 84% UK population for indoor coverage, with the roll out continuing throughout 2017.

Advanced SIM Tariff Features & Benefits

Feel At Home

On Three Advanced Plans you can use your allowances in 60 destinations worldwide to call and text the UK and use your data at no extra cost. Terms apply.

Personal Hotspot

Share your phone’s internet with other devices such as tablets and laptops. This can be really handy when you’re away from a WiFi network. You can use all of your data allowance as a personal hotspot unless you’ve chosen a plan with All-you-can-eat data in which case you can use up to 30GB of this each month as a personal hotspot allowance in the UK.

Free WiFi on the London Underground

As simple as connecting to your home Wi-Fi, you can connect to Free WiFi at over 130 London Underground stations, using any device. You just need to be an active Three user.

Data Add-on

If you find yourself needing more data or an increased personal hotspot allowance for the remainder of your current bill cycle, you can choose from a range of short-term Data Add-ons to suit your needs.

Track & Control Your Network Usage

Three allow you to track and manage your monthly usage directly from your phone, or from a computer. Simply Log into your My3 account online or download the Three App to view your itemised bills, check to see if you're eligible for an upgrade, find out about existing customer deals, update your personal details and more.
