One SIM Card Review

Created in 2007, OneSIM Card is a division of Massachusetts-based Belmont Telecom offering travelers various international SIM card options. As the name suggests, OneSIMCard is supposed to be the only SIM card you’ll ever need for convenient global travel. Indeed, according to the company, a OneSIMCard could cut international roaming charges by 85 percent.

So, does this product live up to its lofty claims? And, if so, what OneSIMCard is right for you? Check out our OneSIMCard review to learn exactly what this company has to offer. 

A Closer Look At OneSIMCard’s Three Main Options

Currently, OneSIMCard has three major SIM cards to choose from:

  • Universal SIM
  • Expedition
  • Europe & More

All three of these cards offer voice and SMS texting in over 200 countries as well as free incoming SMS texts. Not all of these cards, however, offer free incoming calls in the same nations. Universal SIM has free incoming calls in roughly 130 countries, while Expedition offers 110 and Europe & More offers 70.

Another key distinction between these cards has to do with Direct Dial versus Callback. Only the Universal SIM offers Direct Dial (in about 70 countries) as well as Callback. Those who opt for the Expedition card can only use Callback, whereas Europe & More cardholders must use Direct Dial in select nations.

Rates

While the data rate per MB—listed from $0.01—is the same for all three cards, they differ in the starting fee for calls from Western Europe back to the USA. The Universal SIM and Expedition have rates from $0.29 per minute while the Europe & More card offers costs from $0.25 per minute.

The only other major distinction between these cards is the Universal SIM offers customers special discount voice packages. To see all of the discount voice packages available, you can view a comprehensive list on OneSIMCard’s FAQ page.

By the way, prices on the OneSIMCard website are set at $30 for Universal SIM, $35 for Expedition, and $20 for Europe & More.
