Thailand travel tips
- Many Thailand trips mix Bangkok with the islands, such as Phuket, Koh Samui, Koh Phangan or Koh Lipe. Big cities are usually well covered, but signal on smaller islands, boats and beaches can vary. Check the provider's coverage map for the islands you're visiting.
- Long stays and backpacking trips are common in Thailand, so look at 15- and 30-day plans and price per GB, not just the cheapest week. If you're travelling with a partner or friends and want to share one plan, check the hotspot column before you buy.
- Ride-hailing apps such as Grab and Bolt need data to book and to track your driver, so don't let your plan run to zero on a late-night ride back to your hotel.
- If your plan runs low mid-trip, many providers let you top up or buy another plan in their app. Install the eSIM at home on Wi-Fi, and keep your Australian SIM on for SMS codes with its data roaming switched off.

Will my eSIM work on the Thai islands?
Popular islands usually have mobile coverage, but it can vary on smaller islands, boats and remote beaches. Check the provider's coverage map for the islands on your itinerary.
Is unlimited data worth it for Thailand?
It can be on a long trip, or if you stream, hotspot or use a lot of maps. For lighter use, a fixed-GB plan is often cheaper. Compare both in the table above, and check unlimited plans for fair-use limits.
Can I top up my Thailand eSIM mid-trip?
Many providers let you add data or buy another plan in their app. Check the provider's top-up options before you buy.
Does a travel eSIM work for Grab and Bolt in Thailand?
Yes. Both apps run over mobile data, so a data-only eSIM is enough. Keep your Australian SIM on if you need SMS codes for sign-in or payment.
