What is the best eSIM for Thailand?
+
eSIMbundle is the best choice for travellers who want reliable Thailand mobile data, simple online top-ups and VPN-powered private, unrestricted internet in one plan. Buy before departure, connect after landing and use Grab, Google Maps, WhatsApp, translation and bookings without visiting an airport SIM counter.
Which mobile network does eSIMbundle use in Thailand?
+
In Thailand, eSIMbundle connects to AIS. Your eSIM joins it automatically after landing, so you never need to choose a carrier. AIS supports 4G and 5G.
Does eSIMbundle have good coverage across Thailand?
+
Thailand has strong mobile coverage across Bangkok, Phuket, Chiang Mai, Pattaya, Krabi and other populated tourist areas. Coverage is also available across many islands and regional destinations, although signal can be weaker on remote beaches, boat routes, in national parks and in mountainous areas.
Is 5G available with a Thailand eSIM, and how fast is it?
+
4G is widely available across Thailand, while 5G is available in many populated areas. Whether your phone connects on 4G or 5G depends on your device, location, available partner network and live network conditions. Thailand’s independently measured mobile speeds are comfortably suitable for navigation, messaging, video calls, uploads and streaming.
How much data do I need for 7, 15 or 30 days in Thailand?
+
Light users on Maps and messaging often manage on 1–3 GB a week. Normal travellers using social media, navigation and bookings usually want 5–10 GB a week. Heavy video, streaming or hotspot use can push past 20 GB a week or benefit from an unlimited plan. Use the Travel Data Calculator to estimate your usage and pick a Thailand plan that fits.
Can I get unlimited data for Thailand?
+
Yes. eSIMbundle currently offers unlimited Thailand plans. Available durations and current usage conditions are shown on each plan before checkout.
Does a Thailand eSIM include a Thai phone number, calls or SMS?
+
eSIMbundle Thailand plans are data plans. Use mobile data for WhatsApp, FaceTime and other internet-based calling and messaging services. You can keep your normal SIM active for calls, SMS and verification messages, subject to your home carrier’s roaming charges and support.
Can I keep my normal SIM, phone number and WhatsApp?
+
Yes. On a compatible dual-SIM phone, keep your normal SIM installed and use your eSIMbundle eSIM for mobile data. Your normal phone number remains connected to your home SIM, and WhatsApp continues using the number already registered to your account.
Can I add more data while I am in Thailand?
+
Yes. In the eSIMbundle app, open Store or Add data and buy a separate bundle on the same installed profile. Each bundle has its own allowance and validity and may wait before first use. Eligible finite bundles offer saved-card auto top-up at 80% used, up to your approved package price. Manage it under Account → Auto top-up; check existing replacement orders before buying again.
Should I buy my Thailand eSIM before travelling?
+
Yes. Open the eSIMbundle app → Account → My eSIM → Set up your eSIM and use Install eSIM on this phone, or QR/manual fallback. Confirm the profile appears in phone settings. Installation does not start the bundle; first supported use in coverage does. At your destination, enable the line, select it for data and enable its Data Roaming setting. Keep the profile after the trip.
Does eSIMbundle include a VPN in Thailand?
+
Yes. Use VPN inside the eSIMbundle app with your normal account. VPN connection requires an active qualifying bundle, including on Wi-Fi. Prepare the app before departure; a bundle awaiting first use may not yet provide access. Choose a country and connect. VPN does not guarantee access to every service.
