SIM plan benefits
Personal Hotspot
If you're taking out one of our plans, you can use all of your data allowance as a Personal Hotspot in the UK.
Unlimited texts
All our plans come with unlimited texts, so you can send as many standard rate text messages as your fingers can type in the UK.
Use your phone abroad at for a low daily charge
Unlock your allowance in Go Roam destinations for a low daily charge: £2 in Europe, £5 Around the World. If your plan started before 1 October 2021, you won’t be affected while you stay on that plan. If your plan started on or after this date, we’re waiving the charge until 23 May 2022. Find out more about Go Roam.
Control your spending
If you run out of minutes, you can block outgoing calls so you don't run up any extra charges. Plus, you can block calls and texts to numbers that always fall outside of your allowance (like 0845 and 118).
Add extra data any time
Don't worry if you run out of data halfway through the month. You can buy more any time you like in your My3 account, giving you all the flexibility you need.
Set usage limits and alerts
Along with our fixed data allowances, our usage alerts for minutes and data make sure you never spend more than you planned.
Switching to a new SIM plan
Already on one of our older plans? As your minimum term has ended, you can switch to one of our new plans any time you like. It's really easy - we just move your new plan details on to your existing SIM.
Keep your existing number
Joining us from another network? We’d love to have you. To keep your own number, text ‘PAC’ to 65075 to get your code, and then switch to Three.
Delivery of your SIM
Sign up to one of our new plans today and you'll have your new SIM in 3 working days.
Contract and billing
When you buy a SIM from our website, you’ll need to activate it when you receive it. Your plan will begin once activation is complete. Your first bill will be a bit higher than your usual monthly charge, because you'll be charged for up to nine days extra. This is so you can get connected as soon as you’ve got your device. After your first bill it should go back to normal. Then, your remaining payments are due on the same date each month until the end of your 12 or 24 month contract.
