What is an eSIM, and why should you use one in Thailand?
An eSIM, which is actually short for embedded SIM, is a digital SIM card built into your phone or device. Instead of inserting a physical card, you download an eSIM profile from a provider, which gives you access to a mobile network in your chosen country or region (depending on what you choose).
Why use an eSIM in Thailand?
- Convenience: No need to visit shops or deal with local SIM cards.
- Cost-Effective: Avoid expensive roaming fees from your home provider.
- Flexibility: Easily switch between eSIM providers or plans.
- Reliability: Get a strong connection in cities, rural areas, and even on islands.
