The small print

If possible, please ensure you use up any remaining credit on your old SIM card as we cannot refund any airtime once you have posted it back to us. You should also make sure that any contact details are removed from the SIM card as it will be destroyed and recycled as soon as we receive it.

This offer only applies to Global or Internationa SIM cards from the suppliers listed above and does not apply to any other types e.g. 'local' country specific SIM cards (i.e. for Spain, USA etc).

Talk longer for less

Great call rates mean saving you up to 85% off international calls in over 175 countries worldwide. Which means you can talk longer for less. In fact you can talk six times longer than you would with a standard network provider. What's more, with GO-SIM, you don't pay roaming charges in over 75 countries, so you won't be charged if someone calls or texts you either.

Unused credit never expires

Plus, on top of all this, your global SIM and any credit on it never expires, so you have an international number for life. Perfect if you travel regularly and are partial to the odd holiday or two!
