Frequently asked questions.
-
What is a SIM Only deal?
-
A SIM Only contract is just that. No phone or tablet, just a SIM card with all the data, minutes and texts you need. Pick a Pay Monthly or Pay As You Go plan that suits you. You get extra flexibility with Pay Monthly, because you can join us on a 1, 12 or 24-month plan. And if you choose Pay As You Go there's no upfront cost.
-
Why SIM Only?
-
If you don't want a new phone, but your current contract is up, then SIM Only is perfect. You get extra flexibility with Pay Monthly, because you can join us on a 1, 12 or 24-month plan. And if you choose Pay As You Go there's no upfront cost. Simply send a text to switch to Three and keep your number.
-
Can I keep my phone number if I switch to SIM Only?
-
Yes, you can. It’s easy to do it online, or even via text. Just let us know your PAC code from your previous provider. Find out all you need to know about switching to Three.
-
Can you cancel a SIM Only contract?
-
If you're currently using a Pay As You Go SIM, then you'll be able to leave at any time. If you're on one of our Pay Monthly SIM Only contracts, then you'll be able to cancel when that contract is up for renewal. The Pay Monthly SIM Only contracts last 1, 12 or 24 months.
-
Can I use WhatsApp with SIM Only?
-
Yes, with SIM Only you can still use all your favourite web messaging services, like WhatsApp and Facebook Messenger. Any data use will come out of your SIM plan allowance.

Can I get 5G coverage with a SIM Only plan?
-
Yes, as long as you have a 5G device and you’re in a 5G area, our SIMs will have you covered. Take a look at our 5G coverage checker.

Can I use my SIM Only plan abroad?
