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.
Go Roam with us
With Three, you can Go Roam in 71 destinations around the world – up to 12GB. There’s a daily charge to unlock your UK allowance for 24 hours abroad: £2 for Go Roam in Europe destinations, and £5 for Go Roam Around the World destinations. 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.

Delivery of your SIM

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.
Switch
*Get £100 pre-paid Mastercard when you switch to Three. Send us your PAC code within 14 days of purchase. The pre-paid Mastercard will arrive 45 days after purchase.
