What is an international SIM card and how does it work?

International SIM cards are pre-paid travel tools that provide a set amount of data, calls, and texts for use abroad. These cards connect to local networks in your destination country, allowing you to pay local-like rates instead of expensive international roaming fees.

Physical SIM vs. eSIM

You have two main choices:

  • Physical SIM: A plastic card you insert into your phone's tray.
  • eSIM (Digital SIM): A software-based SIM that you download via a QR code or app. If you’re strictly looking for digital SIM options, check out our guide on the best eSIMs for international travel.

However, these services are usually charged at a much higher rate than your standard plan or travel SIM cards, which is why many people decide to use a dedicated travel SIM when going abroad.

  • Generally affordable - Travel SIM cards are generally considered to be more affordable than roaming charges or a roaming plan.
  • Prepaid- Most travel SIM cards are prepaid, meaning that you may for a set amount per month/time period that you’re abroad in return for a number of texts, minutes, and/or data.
  • Compatible with different devices - If you plan on using a tablet or other phone while away, travel SIM cards are usually compatible with a range of devices.
  • Incoming calls are generally free - You won’t typically be charged for incoming calls when using a travel SIM card, whereas you may be charged to accept an incoming call with standard roaming rates.
