What services does WorldSIM offer?

WorldSIM’s entire business centers around its international SIM cards. You’ll find no monthly contracts or phones for sale. Instead, WorldSIM offers prepaid roaming services with coverage in over 200 countries worldwide.

Here are a few of their key products:

  • International SIM card. Add credit to your SIM card. Your calls, texts and data usage are charged against your current balance. And if you need more credit, you can top up online or contact customer service.
  • Virtual phone number. Combine this service with your international SIM card to get a local phone number in over 50 countries. You’ll pay local call rates when you’re in that country, saving you exorbitant international roaming charges.
  • Data bundles. Add international data packages available in over 100 countries.

How much does WorldSIM cost?

WorldSIM doesn’t charge anything for its international SIM cards alone, but you need to add credit to your SIM card before you can use it. You can top up in a range of increments from $15 to $150. The more you top up in one go, the more bonus credit you earn.

Call rates, texts and data with WorldSIM vary depending on where you’re located and the country you’re contacting. For example, calling from the United States to the Dominican Republic costs $0.42 a minute, while texts will run you $0.23 a piece. And you’ll pay $0.28 per MB without a data bundle.

How do I top up with WorldSIM?

WorldSIM makes topping up easy no matter where you are. You can add money on its website, set your SIM to top itself up automatically or dial 190 from your WorldSIM to reload for free.

Pros and cons

Here are a few highlights and drawbacks of WorldSIM.


  • 4G network support. WorldSIM connects you to 4G networks for high-speed Internet access in countries where they’re available.
  • 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 trouble with your WorldSIM service, you can call its multilingual support team any time of the day.
  • 365-day credit expiry. You have a year to use up your credit.


  • Highly-variable call and text rates. WorldSIM’s call and data rates can change significantly from country to country, meaning you need to do your research before traveling to ensure you have enough credit to get you by.
  • Pricey data rates. We’ve found WorldSIM’s data bundles are more expensive than local data options in a few countries.
  • 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.
  • Monthly recurring charge. All SIM cards have a recurring monthly charge of equivalent to £1 — approximately $1.35 — regardless of whether you use the card.

Bottom line

WorldSIM’s coverage is impressive and you’ll get competitive rates to call and text other countries. But its data plans are expensive, and you’ll need to budget for its monthly recurring charge hidden in the fine print. Read our guide on SIM cards if you want to compare more options.
