SIM only

Three SIM-Only

A SIM Only plan gives you all the benefits of a pay monthly deal, like inclusive minutes, texts and data, without the added cost of paying off a new phone. You can keep your old phone or buy a new one outright, and the monthly cost of your contract is kept much lower. Three has a range of popular pay monthly SIM Only deals which are all great value for money.

SIM Only on Three

Three is a leading provider of SIM Only deals because its plans offer impressive value. The monthly cost is already kept low because you’re not paying off the cost of a new phone, but you’ll also find that Three offers eye-catching allowances for calls, texts and web with its SIM Only plans. There is a choice of 1 month rolling and 12 month fixed plans, so you don’t have to commit long-term, and the range of plans makes it easier to find the ideal one.

SIM Only plans

The One Plan

Choose between 1 and 12 month plans, and get thousands of minutes and texts, plus loads of data for web browsing.

Ultimate Internet

Get all-you-can-eat data for unlimited web browsing, loads of texts each month and a choice of monthly any network minutes.

Essential Internet

Pick from a range of calls and data allowances, and get thousands of texts included with your plan.

BlackBerry tariff

Three offers a tariff specifically for BlackBerry users, which comes with BlackBerry Internet Services included.

Three Pay As You Go

With pay as you go there’s no contract or long-term commitment, so you just top-up with Three whenever you need more credit and you are never out of control of your spending. Even though you can’t get the same generous allowances as you do with pay monthly or SIM Only, there are still great benefits available and some good value for money deals.

Pay as you go on Three

As a leading mobile network, Three aims to provide a great range of deals for customers, even if they are not taking a contract. With pay as you go, you buy your new phone outright, and there is no monthly agreement in place. Top-up with Three whenever you choose, and with Three Add-ons you can get more value from your credit.

Three Add-ons

Three Add-ons trigger allowances, so when you top-up you can choose one and have it added to your phone. The cost gets deducted from your credit, and you can choose from comprehensive Add-ons, adding calls, texts and web, or specific Add-ons which are cheaper and just boost one single benefit, such as texts or data. Each Add-on lasts 30 days.

Pay as you go phones

You can choose from a wide selection of smartphones to take with your pay as you go deal from Three. As it’s not a contract deal, you do not get a free smartphone, but the phone is 100% yours from the start, and there is no commitment to continue topping up regularly – you are free to add credit and get Add-ons whenever you like.

Switching to Three

If you are with another network and want to switch to Three then its’ easy and you can keep your number. You would need to contact your current network and request your PAC (Port Authorisation Code), but as long as you are not bound by a contract or agreement elsewhere then switching is simple, fast and free.
