eSIM Technical Specs
Network Coverage

Activation Policy
The validity period begins when the eSIM connects to any supported network in Thailand. You can install it before you fly.

ID Verification (eKYC)

Internet data plans for Thailand
When selecting a package, consider your trip duration and travel habits: navigation, messaging, and ticket confirmation require far less data than video conferencing, streaming, or laptop tethering. Those traveling for just a few days primarily for maps and chat apps usually need a smaller allowance. For extended stays with frequent transfers across provinces, data consumption increases.
How many gigabytes do you need for your trip
| Trip purpose & usage scenario | Duration | Data amount |
|---|---|---|
| Maps, instant messages & digital tickets | 3–5 days | 1–3 GB |
| GPS navigation, photos & social networks | 7 days | 3–5 GB |
| Tours, active maps & photo sharing | 10–14 days | 5–10 GB |
Note: Video calls, streaming media, and sharing data via hotspot require more capacity. Check our data calculator to choose the right package; estimates in the table are recommendations.
4G and 5G Coverage in Thailand
Thailand features widespread 4G/LTE coverage across the entire country. 5G is available in major metropolitan centers and prominent tourist resort areas; reception quality depends on urban density and mountainous topography. Mobile networks are generally denser in big cities than in rural provinces. On long road transfers, it is best to download maps, tickets, and addresses offline in advance.
Nationwide LTE
Reliable high-speed reception in cities, resort strips, and highways.
High-speed 5G
Available in Bangkok and popular tourist destination centers.
Internet across different regions of Thailand
Thailand blends bustling megacities, mountain settlements, agricultural provinces, and tropical islands. Mobile connectivity conditions differ, so consider your itinerary geography.
Bangkok
In the capital, mobile data is essential at every step: hailing taxis, finding metro stations, verifying routes, booking tours, and cashless payments. Your smartphone simplifies navigating the urban transit network where street signs and interchanges can be confusing.
Pattaya & surroundings
In resort areas, internet is used to find beaches, seaside cafes, points of interest, and day trips outside the downtown center. Outside central districts, connection strength may vary.
Chiang Mai & Northern Provinces
In northern Thailand, travelers visit ancient temples, night markets, national parks, and highland hill tribe villages. While Chiang Mai city has great coverage, remote mountain passes may experience weaker reception.
Phuket
Across the island, internet helps you navigate between beaches, book boat charters, arrange taxis, and message hotels. On coastal roads and secluded capes, signal strength can fluctuate.
Koh Samui & neighboring islands
On Samui, mobile connectivity keeps you connected between beaches, restaurants, and viewpoints. During ferry crossings and visits to smaller islands, signal depends on local cell towers.
Who is eSIM in Thailand for?
Select a scenario that matches your travel itinerary and lifestyle needs.
Internet for tourists
For city navigation, messaging, hotel lookups, and taxi ordering, 3–5 GB is sufficient for 5–7 days. For itineraries across multiple cities with active photo sharing and social media over 10–14 days, plan for 5–10 GB.
Internet for road trips
During car road trips, mobile internet is vital for GPS maps, locating petrol stations, parking, hotels, and staying connected on the highway. For 10–14 days, 5–10 GB is recommended. Be sure to download offline maps for remote roads.
Internet for remote work
For corporate email, Slack/Telegram chats, and documents for 1–2 weeks, 5–10 GB is usually sufficient. With regular Zoom/Meet video calls, cloud sync, and hotspot sharing with your laptop, estimate 15–25 GB or more.
