What is a SIM card and why does it matter?

A SIM card, or subscriber identity module, is one of the most essential parts of any cell phone. It stores information about the subscriber’s account with the cell phone carrier, from their phone number to their contact information to their usage statistics and even payment information. A SIM card can be removed from one cell phone and placed in another, meaning that consumers can take their accounts with them and easily switch phones if they wish. This makes SIM cards great for mobile phones but also for other devices like tablets and computers. Keep reading to learn more about what SIM cards are, why they matter and how they work!

How to choose

The first thing to think about when choosing a SIM card is whether you want one that supports your device’s network technology. This can be either GSM (Global System for Mobile Communications) or CDMA (Code Division Multiple Access). GSM-based carriers are more widely available in foreign countries, but CDMA networks are better if you’re located in an area where coverage by multiple providers is spotty.

Where to buy

If you’re travelling internationally, your mobile phone will probably be useless unless you buy a local SIM card to use with your service provider. You can buy these at any convenience store or mobile-phone shop in any country around the world. It will only take about 10 minutes of your time and might save you upwards of $100 per month on charges that would otherwise be put through from another country.
