Other SIM Only Deals

24 Month SIM Cards

If you’re willing to sign up for a 24-month contract, Three currently offers 24-month SIM cards from £9/month.

On a 24-month plan, you’ll occasionally be able to benefit from special offers like the first 6 months at half price when you take unlimited data on a 24-month contract.

However, given the other offers that are currently available, we think the majority of people will be better off choosing a shorter 12-month SIM card instead.

1 Month SIM Cards

For ultimate flexibility, you can choose to get a SIM card from Three on a one-month rolling basis.

Here, you’ll get a one-month SIM card from £16/month, or from £24/month if you’d like a plan with unlimited data.

This tends to be a lot more expensive than the comparable 12-month plan so we’d normally recommend going for the 12-month option if possible.

Go Roam Around The World

All of Three’s SIM-only plans come with access to Go Roam Around The World. This allows you to use your normal UK plan allowances at no extra cost when travelling to 71 countries (including most European countries, the USA, Australia, Brazil, Singapore and more). You’ll also get a Hands Free upgrade each time you fly abroad with easyJet.

Go Roam is subject to a fair usage limit of 20GB per month in other European countries and 12GB per month in non-European countries. If you’re travelling outside Europe, the use of tethering and personal hotspot is not included.

For more information, read our guide to Go Roam on Three.

Go Binge

On Three SIM-only plans with at least 12GB of data per month, you’ll get access to Three’s Go Binge service.

Go Binge gives you unlimited zero-rated data for use on Netflix, TV Player, Snapchat, Soundcloud, Deezer and Apple Music. It means usage of these services will not count towards your normal download limit, allowing you to binge on TV, movies, music and social media without worrying about your download allowance.

For more information, see our guide to Go Binge on Three.

Unlimited Data

You can get an unlimited data SIM card on Three from £18/month. There are no fair usage policies or hidden limits on how much you’re able to download each month.

Most other UK mobile networks now also offer the option of an unlimited data plan. However, Three’s £18/month plan remains one of the better value options and has no hidden limits on the amount you can download. There are also no restrictions on the download speed available.

Personal Hotspot

Tethering or personal hotspot refers to the process of sharing your smartphone’s internet connection with another device (e.g. with your laptop or tablet). It’s often used as a convenient way to share your download allowance with other devices, either when you’re at home or out and about.

On all of Three’s SIM-only deals, you can use tethering and personal hotspot inside the UK and EU. This includes if you’re using one of Three’s unlimited data plans. Any data consumed through tethering will be deducted from your allowance as normal.

Coverage

In the UK, Three offers 99.8% population coverage. This includes 98.3% population coverage on their 3G network and 99.8% population coverage on their 4G network.

You’ll get access to the same coverage from Three, regardless of which SIM-only plan you choose from them. Before signing up to a SIM-only deal, it’s worth double-checking the coverage where you live:
