What is an international SIM card?

Before we get into international sim cards, let’s understand what a ‘Sim Card’ is. A SIM stands for Subscriber Identity Module, and stores basic information like name and number about the user of the phone. It is a small plastic card that goes inside your phone and uses the Global System of Mobile Communications, or GSM, for short. A sim card allows you to make calls, send messages and access the internet. In the same vein, an international sim card has the same functionality as a normal sim card but can be used worldwide.

An international SIM card or travel SIM card allows you to connect to a local network in various countries around the world. In this manner, you can avoid excessive roaming fees that your local operator or carrier may charge when you are abroad. While buying a local SIM card may prove marginally cheaper if you are staying in one country for extended periods of time, an international SIM is a far more flexible option for frequent travelers, especially if you have several destinations during your trip. International SIM cards are all about convenience. Here are some advantages of using an international SIM card like

How Does An International Sim Card Work?

An international sim card is very different from a local sim card. Local sim cards are programmed to operate on only one network, which exists in a specific geographical location. On the other hand, international sim cards are programmed to work on multiple networks in different geographical locations around the world. For instance, many mobile phones in the U.S. and Canada are locked to use the local infrastructure as set by the respective mobile network provider.

International sim cards allow users to connect to different networks in the world without being charged outrageously for making or receiving calls. This is possible because carriers make bilateral agreements with other carriers ahead of time to allow each other’s customers to use telecommunications networks across the globe. Many SIM cards built for travel, use call-back technology that transforms outbound calls into inbound ones for phone calls. Carriers have set in motion this system to automatically reduce the expenses paid by consumers who have acquired a roaming card. This ensures that operators do not have to employ staff to physically intercept calls and reduce their customers’ bills by hand.
