WorldSIM is a SIM-only mobile provider with global network coverage. Established in 2006, WorldSIM aims to streamline communication for international travellers by providing a single SIM that you can use worldwide, free from the high global roaming rates many other mobile providers charge.

What services does WorldSIM offer?

WorldSIM's entire business is built around its international SIM cards. You'll find no monthly contracts or subsidised handsets on offer; instead, WorldSIM offers its roaming services on a prepaid basis. This means you'll need to top up your WorldSIM SIM card before you can use it, with all calls, texts, and data usage charged against your current balance.

Thanks to partnerships with local network providers, WorldSIM's international coverage extends to over 200 countries across the world. Incoming calls are free in over 95 of these countries, and you'll also have access to 4G networks in all countries where they're available.

In addition to standard phone services, WorldSIM offers international data bundles for over 100 countries, with packs ranging from 100MB of data with a 3-day expiry to 1GB of data with a 30-day expiry. These data bundles work out considerably cheaper than paying for data on a per-MB basis.

Finally, WorldSIM also provides a virtual phone number service that lets you add phone numbers from over 50 countries to your SIM card. By adding a number from a supported country to your SIM, you'll only pay local call rates when you're in that country, saving you from exorbitant international roaming charges.

How much does WorldSIM cost?

WorldSIM doesn't charge anything for its international SIM cards by themselves, but you'll need to top a SIM up before you can use it. You can top up in a range of increments starting at $20 going all the way up to $200. The more you top up in one go, the more bonus credit you'll earn.

Call rates with WorldSIM vary depending on where you're calling to and from. Calling from Australia to the United States, for example, is charged at 40c a minute, while calling from the Dominican Republic to the Bahamas will run you $1.31 a minute. Text rates and data usage follow a similarly variable pricing model.

Pricing for WorldSIM's international data bundles is just as dependent on the country you're travelling to. For instance, a 3-day, 100MB data bundle will set you back $12.60 for use in the UK but $13.50 in the USA. The 30-day, 1GB bundle ranges from $59.99 for use in Brazil to $99.00 in Barbados.

How do I top up with WorldSIM?

WorldSIM makes topping up easy no matter where you are. You can log in to the WorldSIM website and top up there, set your SIM to automatically top itself up or simply free call 190 from your WorldSIM SIM card.

What extras does WorldSIM offer?

As a prepaid mobile provider, WorldSIM doesn't offer much in the way of extras. A 24/7 customer support line is commendable, though, as is having 365 days to use your credit before it expires. Beyond that, the free UK and USA phone numbers that come with all WorldSIM's international SIM cards are a nice plus.


  • 4G network support. In countries where they're available, WorldSIM will connect you to 4G networks for high-speed Internet access.
  • Global network coverage. With over 200 countries covered by its service, WorldSIM lives up to its promise of worldwide coverage.
  • 24/7 customer service. If you have any troubles with your WorldSIM service, you'll be able to call its multilingual support team any time of the day.
  • 365-day credit expiry. Not having to worry about topping up every month to avoid losing your leftover credit is a big plus.


  • Highly-variable call and data rates. WorldSIM's call and data rates can change significantly from country to country, meaning you'll need to do your research before travelling to ensure you have enough credit to get you by.
  • You can't keep your existing number. You'll have to use the new country-specific phone numbers WorldSIM assigns you, and keeping track of them all can be a hassle.
  • No contract plans. If you're after the set-and-forget simplicity of a monthly contract, you won't find it here.
