What is an eSIM, and why should you use one in Bangkok?

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 Bangkok?

• 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 central districts and even in outlying areas.
