Do you regularly call a number of people in different countries outside of the UK? Maybe you’re in a business that requires you to call overseas clients or maybe you have family who live abroad.

Making a lot of international calls on a standard rate can get expensive, so you might be thinking of getting an international SIM card. Whatever your reason for making frequent calls abroad, an international SIM or an international calls bolt-on to your existing mobile plan will save you a lot of money. We've laid out all the options right here.

International SIMs from EE

EE Mobile

There are two options for calling abroad with EE. The first is an international SIM – choose from the £10 International Pack or the £15 version. The SIMs last for 30 days. The £10 package comes with 500MB data, 150 minutes, and 150 texts. Or for £15, you get 3GB data, 250 minutes, and 500 texts. You can buy an EE International SIM card on the EE website, where there’s also a tool for checking which countries are included.

The second option is an international add-on for existing EE customers. Choose from the International for £10 per month (this covers 50 countries and comes with 500 minutes) or the International Extra pack for £15 per month (which covers 100 countries and comes with 250 minutes). To buy, simply text 500INTL1 for the International or 250INTL2 for the International Extra. Just make sure you check which countries are covered in each add-on before you buy.
