What is an international SIM card?

OneSimCard is an international mobile service for savvy travelers to greatly reduce the cost of using a cell phone or other mobile device while traveling internationally. Save 85% or more on international roaming charges by using our international SIM card when you travel outside of your home country.

Similarly, you may ask, are iPhones unlocked internationally?

In the US, an iPhone is “locked” (there has been some debate as to whether or not the iPhone 5 comes locked) which essentially means it will only operate with the carrier through which you have a contract. However, many US cell phone carriers will unlock your iPhone for international use only.

Do us iPhones work in Europe?

The second thing you need to know is that only GSM iPhones sold by AT&T, T-Mobile, and Apple in the USA use the mobile phone technology found in Europe and most countries around the globe. Sprint's and Verizon's CDMA iPhones (5s and newer) add GSM capability so they will also work in Europe and internationally.
