Much more than just a UK SIM card

Cheap international calls

With international calls from 1 per minute you can talk for longer, more often. Get low cost rates around the world from one global SIM card. Staying in contact with friends, family and business contacts abroad doesn’t have to cost the earth!

Free international roaming

With big network operators you could pay £1.30 just to receive a call while abroad. Our travel SIM enables you to receive calls for free in 95 countries. In countries where roaming isn’t free it’s greatly reduced and costs from as little as 20 per min.

Low cost UK calls

If you are a pay as you go user with one of the big network providers, it’s likely that you are paying 25p per minute, or more, for UK calls. Our global SIM gives you UK calls at just 7p per minute. We have simplified our prices so you pay one price for all your UK calls and text messages.

Turn your data roaming on

Post your holiday photos and browse the web when you travel without having to waste time searching for free Wi-Fi; our data roaming rates are super low so you can stay connected for less every time you travel.


Do you need to call any other countries, outside of covered bundle?
If you need to call any other countries, don't worry, simply add Pay As You Go credit once your sim card arrives. You can then call anywhere in the world at a super low rate as well as use your sim card outside Europe. See our Pay As You Go Rates below.
How to activate your bundle when you are ready to use it.
After you have purchased an Europe SIM card bundle you can activate it whenever you are ready within the My Bundles section in My Account. You can also purchase a bundle from your Pay As you Go credit by dialling the relevant short code. This will activate your bundle immediately (a shortcode is a number that looks like 83423 that enables you to buy a bundle with your existing credit.)
My bundle has run out. How do I add another bundle?
If you need to add another bundle to your existing Europe Sim card you can easily do so by adding Pay As you Go Credit to your sim card by topping up your existing number. Then simply dial the short code that is shown below the bundle e.g. for 3GB and 500 mins bundle dial *126*83423#

Great SIM! Perfect for a longer trip abroad!

As a first time user, I am very satisfied. There's a bit of a learning curve if you've never used a SIM before, which was my situation, but it doesn't take long to figure things out. And the rates are superb! It's so nice not to have to worry about excessive roaming charges on your "home" carrier.

My WorldSIM experience was just what I was hoping for

Activating the service was immediate – just turned on my phone and I was connected. As I traveled through six countries, I always had efficient service to call a local restaurant or to call home thousands of miles away.

Perfect for travelers!

I used WorldSIM several times during my trips in Europe and America without any problems. The phone changed the networks automatically and I never lost the signal. Very good coverage on those areas.

Essential travel companion

I travel to the US a few times a year and have been using a WorldSim card for a while. I have just upgraded to their new card and am very pleased. The rates are unbeatable and the process of moving my credit and number over went smoothly.

I purchased the World SIM a few months back and since then I have used it in various countries with great satisfaction. The pricing structure is very competitive and service is highly reliable. If you travel to various countries and need a great world product then this SIM is the right move.
