Only insert your SIM card in your device once you have arrived in Europe or your Roam destination to avoid activating your service before the start of your trip. Your 30-day service will commence as soon as you insert the SIM card into your device.
When you insert it in your phone, and you’ll receive a text message telling you your SIM is ready to use. The best thing to do is to register on the Three app, so you can keep an eye on your usage and your spend. The SIM is automatically activated as soon as you make a call, send a text, or use your data.
What is my new phone number and can I find it before I travel?
Your number will be sent to you via text once your SIM has been activated. Unfortunately, there is not way for us to provide your number beforehand.
This is a UK mobile number, so in order to call it, the country code (+44) will need to be added.
For example :Your 3UK number will look something like this - 07123456789 (yes, it will be 11 digits!) For people to reach you on this number, they will need to drop the first zero and dial +447123456789Please note that your number will stay the same (with the same country code prefix!) regardless of which country you are in

How do I keep my Pay As You Go number active?
To keep your Pay As You Go number active, you must use it for at least one chargeable activity - like making use of existing top-up credit or Data Pack allowance, adding top-up credit, buying a new Data Pack, or making telephone call, sending a text, or using the internet on Three’s mobile network - every 180 days.
What is Data Pack?
A Data Pack lets you exchange your credit for a set amount of data with unlimited minutes and texts. If you use a lot of data, they’re better value than our standard Pay As You Go rates. Data Packs last 1 calendar month and you can change them each month to suit you.
What happens when my Pay As You Go data runs out?
You’ll still get unlimited minutes and texts for the rest of the month, but you’ll be charged our standard rate for any data you use. This will be taken from your existing credit. As you can only buy 1 Data Pack at a time, you'll need to wait for it to expire before you can get a new one.
Are Data Packs like a contract?
No. With a Pay As You Go SIM card on Three, there’s no contract. Data Packs only last a month and there’s no commitment to buy another one. You can go back to using your credit like normal, or buy another Data Pack for the next month. You can even set up auto-renew so you’re always topped up.
What if I need extra data for the rest of the month?
Use the Three app to buy a Data Add-on, or use your credit for data at our standard rate.
What is auto-renew bonus data?
When you set up auto-renew on a Data Pack, you'll get additional bonus data, on us, each month when you auto-renew, which means you can get extra data when you auto-renew on the Three app.
How do I get auto-renew bonus data?
You can activate auto-renew on Three UK app or My3 when you buy a Data Pack. If you already auto-renew and want to get this promotion, it’s easy. First, turn off auto-renew and wait for your Data Pack to expire. Then select a promotional Data Pack and reactivate auto-renew.
What's a Pay As You Go Data SIM?
If you need a Pay As You Go SIM for a mobile device that only uses the internet – i.e. it doesn’t make calls or send texts – like a tablet or a Mobile Broadband hub, then you wouldn’t use a Pay As You Go phone SIM like the ones shown above, you’d need a Pay As You Go Data Only SIM. Take a look at our range of Pay As You Go Data SIM deals.
How does a Pay As You Go SIM work?
Pay As You Go SIMs give you freedom and flexibility, as you only pay for what you use – you’re not tied into a monthly phone contract. Pay As You Go phones and SIM users have recently used Data Packs, which give you a fixed amount of data for a fixed price for a month, which you can renew each month. But this isn’t the same as a contract, as you can opt-in and opt-out of your Data Pack each month. Traditional Pay As You Go users use credit, where you add money to your Pay As You Go account, which gets used up as you make calls, send texts, and use data. You can then top up as you go along.
Do Pay As You Go SIM expire?
Yes, if you don’t use your Pay As You Go SIM for 18 months, then it will expire. Make sure you make a call, send a text, or use your data within this time to keep your SIM active.
Do Pay As You Go SIMs work Abroad?
Yes! As long as you’ve activated your Pay As You Go SIM in the UK before you head abroad, you can use your UK allowance in any of our Go Roam destinations at no extra cost. Activate your SIM by making a call, sending a text, or using your data in the UK before you travel.
How do I top up my Pay As You Go SIM?
There are lots of ways to top up your Pay As You Go SIM. You’ll get the best value by adding a Data Pack and setting up auto-renew.

Can I call the USA or Australia with this SIM?
Unfortunately, this SIM doesn't come with calls/texts to USA or Australian numbers!
