How can I make calls & texts?
This SIM does not come with calls or texts. However, you can use your data to make calls and texts.
We highly recommend using data applications as a smart alternative.
If you are wanting to call internationally:
We recommend using Skype. You can purchase credit and use it to make international calls to any number in the world at very affordable rates that are much cheaper than international call rates. $10 will get you roughly 250 minutes worth of international calls. It's just like using your mobile but it uses internet data to make the call. Very handy! Works for landlines and mobile numbers.
If you are wanting to call and text mobile numbers internationally for free:
We recommend using any of the following free apps:
All of these apps are handy to use while travelling.
How do I check my balance?
You can keep track of your usage by registering a ‘My3’ account with ThreeUK.
Instructions are included in your PDF guide.
This SIM can only be recharged in the UK or with a UK credit card.
If you need more data or a longer duration you will need to purchase multiple SIM cards and swap them out as you go.
If you want more than 1 SIM card, you can checkout with the code: MULTISIM10 for 10% off your order.
How do I find my new number?
Your new UK mobile number is printed on the back of the SIM packaging.
Is this enough data for me?
12GB of data over 365 days is suitable for Google maps and general web browsing.
If you are planning on streaming videos or downloading large files then you may want to grab a second SIM card for more data.
So worth it!
This sim was so worth the money! It made my travel so smooth and hassle-free as there was no need to change sims country to country. The staff were also super helpful, quick to respond whenever I had a question
Great product - exactly as described
I I first bought a Sim when we were going to Sri Lanka and it was fabulous and because it was a travelling man I can use it in other places and it was great value. I also went to Japan recently and my partner and I could not exhausted five gigs in 15 days – fabulous product. The Sims are exactly what they held out to be and we loaded them up on the plane and as soon as it landed we were on! Fabulous as we were navigating our way out of airports in parts of the world with never seen
Such a useful global sim!
So good to be able to have roaming data when traveling. When I see I'm in a country that is not included, I get frustrated, but it is bliss to remain connected at an affordable rate whilst you're on the road. The speed is sufficient (not usually fast) and sometimes it is difficult to configure on arrival to a new country.
