Since WorldSIM began in 2006, we have won many awards for our products, our innovation or service and even our travel blog. Our most notable award is for Best Telecoms Provider.


Our vision

The WorldSIM vision is to make global communications the same price wherever you are. We aim to have one SIM that can be used worldwide, with the rates of a local SIM. With hundreds of roaming partners we can already offer free international roaming in over 90 countries and we are adding more all the time. The success of the SIM inspired us to develop many more products and services to assist travellers when they go abroad and we are adding new products all the time.
