Do I need to remove my physical SIM card?

No. Most travellers keep their existing SIM installed and use the Thailand eSIM for mobile data while travelling. Your device must support eSIM functionality and allow multiple SIM profiles.

Can I keep my WhatsApp number while using an eSIM?

Yes. Installing an eSIM does not change your WhatsApp account or phone number. You can continue using WhatsApp as normal while connected through your Thailand eSIM.

Will my Bangkok eSIM work outside Thailand?

These recommended plans are designed primarily for use within Thailand. If your itinerary includes multiple countries, consider one of our regional or global eSIM options for broader coverage.

Can I view all Thailand eSIM plans?

Yes. Use the view all Thailand plans link to compare all available Thailand eSIM plans, including different data amounts, trip durations and daily data options.

Using your eSIM in Bangkok

A few practical details that help you avoid surprises once you land.

When should I install my Bangkok eSIM

Install your Bangkok eSIM before you travel while you still have a stable Wi-Fi connection. Keep it turned off for mobile data until you arrive, then enable the eSIM and data roaming.

How much data do I need for Bangkok

For maps, messaging and light browsing, 1GB to 3GB is often enough for a short trip. Travellers staying one to two weeks typically choose 5GB to 10GB, while daily plans or 20GB+ options suit hotspot use, remote work, video calls and heavier data usage.

Can I use hotspot with a Bangkok eSIM

Yes. Personal hotspot and tethering are supported on all Thailand eSIM plans, allowing you to share your mobile data connection with laptops, tablets and other devices.
