Choose SIMO for Great value

3 SIM Only deals are generally the best value mobile contracts you can get. Keep your existing phone or buy a new one from any source, and take advantage of more texts, minutes and data for the money.

Keep your old phone and keep your old number with minimum hassle. All you need to do is contact your old network to ensure your phone is unlocked, and ask them for a PAC (Port Authorisation Code) – that will enable Three to transfer your old number across to your new SIM.

And remember, with a Three SIM-Only plan you get access to Three’s 5G network for no extra cost. If you’re in an area with 5G coverage and your device is compatible, you can take advantage of super speedy internet on your mobile with a great value All-You-Can-Eat data plan on Three.

3 Triple SIM Card - Why we like it

  • Plenty of data on all 3 SIMO plans.
  • A variety of plans to suit your needs.
  • Compatible with any unlocked 3G, 4G or 5G mobile phone.

How do I get the best value?

SIM contracts are available in 1, 12 or 24 month terms. We think 12 month terms are the best combination of price and flexibility.

Can I tether my laptop or tablet to my SIM Only connection?

You can share your entire data allowance with another device using tethering. iPhones and Android phones both make it easy to fire up a personal hot spot and tether any device.

5G sounds amazing. Can I get it?

Yes you can! All SIMO contracts are 5G enabled so as soon as 5G arrives in your local area it will be available for you to use. You will need a 5G ready phone, which can be bought from a variety of sources.

Will a 3 SIM Card fit and work in my phone?

Good news! 3 SIM cards are all Triple SIMs, so they will definitely fit in your phone. A clever slotting mechanism means you can just press the correct size out and put it straight into your phone.

To connect to the Three network your phone needs to be unlocked. A lot of phones are already unlocked, and if yours isn’t yet then it is usually a simple process.

I think I'm in the wrong place!
