SIM Cards on Three

Three SIM Only

Three is the UK’s fastest growing network, with coverage of over 97% of the UK population. Built for the internet, Three was the first network to introduce mobile broadband with the launch of their 3G network back in 2003.

Three love to be the disrupters of the UK mobile phone industry with unique deal benefits such as inclusive roaming and free calls to non-geographic numbers. They also offer a good range of low cost 4G deals with generous allowances on 30-day and 12 month SIMs.

Why you might like Three

Unlimited data

Get unlimited data including 4GB of tethering on Three

Three’s low cost all-you-can-eat data plans let you do up 1000GB of browsing, gaming and downloading including up to 4GB of data for tethering and 25GB of roaming data in Feel at Home destinations.

No price hikes

Three's price promise means no mod contract price hikes

Three believe the amount you pay throughout the life of your contract should stay the same. So unlike O2, EE and Virgin Mobile you won’t have any mid contract price increases with a Three SIM plan.

Capped contracts for total control 

Cap your bill for peace of mind and total control on Three

If you worry about overspending on your phone bill each month then Three’s flexible caps let you block calls and texts to out of plan numbers, and block all calls and texts once you’ve used up your inclusive allowances. Apart from Tesco Mobile, who let you fix a cap to your bill, Three are the only network to offer capped contracts.

Free roaming in selected countries

Use your allowances in 16 worldwide destinations at no extra cost with Three

Three’s ‘Feel At Home’ lets you use your minutes, texts and data just as you would at home in selected worldwide destinations, including Spain and New Zealand.

Roaming packages are also available from the other big mobile networks including EE, O2 and Vodafone who all let you use your inclusive allowances when you travel from around £2 per day.

Free calls to 0800 numbers

Free calls to 0800 and 0500 number with Three

Three offer completely free calls to 0800 numbers on all new contracts. Free calls to 080 or 050 numbers are also included on all giffgaff Goodybags and on some plans from EE and Virgin Mobile.

Free WiFi on the London Underground

Free WiFi on the London Underground with Three

Just like O2, Vodafone, EE and Virgin Mobile, Three has partnered with Virgin Media to bring absolutely free WiFi to over 100 London Underground stations so you can check maps, update your status and send emails while you wait for your train.

Why you might not like Three

Limited 4G coverage

Three offer limited 4G coverage compared to EE, O2 and Vodafone

While Three has one of the biggest 3G networks, their 4G coverage is still rolling out slowly so check the coverage in your area before you buy. Alternatively, Tesco Mobile also offer 4G at no extra cost and use O2's well established 4G network.

EE and Vodafone are also further forward with their 4G network rollout, but if you like Three and can wait, the network plan to reach 98% of the UK population for 4G coverage by the end of 2015.

One month notice period for 30-day SIMs

Three's 30-day SIMs Three’s 30-day SIMs require a one month notice period, this is not a problem if you want your contract to roll on but it is something to consider if you are only looking for a temporary SIM. Some other networks, like giffgaff, don’t auto-renew unless you request it.

Three sim-only contracts

You can talk even more with free calls to 0800 numbers and you can use your phone abroad at no extra cost with Three’s Feel at Home, available in selected countries including Australia, Italy and the USA. 

There’s no need to worry about mid contract price increases either, because Three are one of the few networks to promise that the price you agree to pay at the start of your contract is the price you'll pay at the end

"Out of bundle" call charges on Three

"Out of bundle" call charges only apply once you've used up all of your monthly allowance, or where you don't have any given allowance included (for instance if you don't have internet/data built into your plan's package). All prices are in pence.
