International SIM Card

The WorldSIM International SIM Card

Unlike many other mobile networks who will charge you a fortune to answer your phone abroad, WorldSIM have hundreds of roaming partners across the globe so we can offer you free incoming calls in over 90 countries. These partnerships enable our customers to benefit from greatly reduced calls, SMS and data in all the popular travel destinations.

A SIM card with 3 Uses

Our SIM card is unique and has three distinct uses – use it one way or all three…

  • A travel SIM – Get free international roaming and worldwide coverage
  • Cheap international calls – Make international phone calls from just 1p per minute
  • A pay as you go SIM – Our rates are about a third of the cost of the leading mobile networks



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!

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 over 90 countries. In countries where roaming isn’t free it’s greatly reduced and costs from as little as 20 per min.

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.
