12 month SIMs: here’s why we love them

Value

As the plans run for a year, you can enjoy better value per month than a shorter plan.

Flexibility

You’re not tied into a super-long contract, which is perfect if your circumstances change.

Upgrades

If, after a year, you’d like to amend your plan or change to a phone contract, we have loads of options.

Why get a 12 month SIM on Three?

What’s a 12 month SIM Only plan?

From only £11, you can connect to our super-fast 5G network for a year. They’re great value, and you can opt for a Value or Complete plan that includes Paramount+ and roaming.

How do 1 year SIMs work?

Our 1 year SIM Only plan gives you access to our network for 12 months. After that, if you’re happy with it, you can renew your contract or upgrade to a 24 month SIM plan, or a plan with a device.

You can keep your existing number

Moving your number across to Three is simple. You’ll need a PAC or STAC code from your current provider, and then it’s just a case of sending a text. Find out how to switch to Three.

Upgrade easily

If you love your 12 month SIM – and we think you will – then upgrading to a plan with a device, or moving to a longer-term SIM plan with Three is simple, and it can all be done online.

Easy activation

Once your SIM arrives, put it in your phone, and you’ll get a text confirming that you’ve connected Three automatically. You’ll be ready to go in no time.

Increase your data limit

If you run out of data, it’s easy to get more. You can increase your monthly allowance or purchase a data Add-on anytime online, and start using your new data straight away.

Once the 12 months have come to an end, you can either renew your 12 month plan, or upgrade to a 24-month contract, or a plan with a device. Otherwise, you’ll be moved to a rolling 1 month contract.
