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?
+
Your eSIMbundle eSIM connects automatically to an available Thai partner network after landing, so you do not need to choose a carrier at the airport. Independently measured Thailand networks recorded very high signal availability and typical download speeds in the 30–45 Mbps range in Opensignal’s June 2025 report, which is fast enough for navigation, calls, streaming and uploads.
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. Sign in to your eSIMbundle account and add another Thailand data bundle whenever you need more. The new bundle is added to the same eSIM already installed on your phone, so there is no new QR code or country eSIM to install.
Should I buy my Thailand eSIM before travelling?
+
Yes. Buy your bundle and install your eSIMbundle eSIM before departure while you have a stable internet connection. You can then arrive in Thailand, turn off airplane mode and connect without finding an airport SIM counter.
Does eSIMbundle include a VPN in Thailand?
+
Yes. VPN is included with every eSIMbundle plan at no extra cost. Turn it on in the app for private, unrestricted internet on Thai mobile networks and on airport, hotel and café Wi-Fi.
