The call rates are very simple, but do vary from country to country.
To see the call rates, simply select the country you will be in and then the country you want to call to in the rate calculator below, then click on Get Rates button.
You will see a table showing the call, text message and data charges for the country you have selected. This is the same idea for all countries covered by the Global SIM card service.
If you are travelling again in the future, although rates don't change often, always check the website for the most up to date information.
