Prepaid data plans for your Thailand trip
esimbloom offers 17 prepaid data plans for Thailand, with options from 100 MB for short stays up to multi-gigabyte bundles for longer trips. Every plan is data-only: you get mobile internet for maps, messaging apps, ride-hailing, and travel bookings, but no Thai phone number or voice calls. Plans start at $0.36 and run from 7 days upward, so you can match the package to your itinerary.
Coverage spans Bangkok, Chiang Mai, Phuket, Krabi, Koh Samui, and smaller towns across the country. Your eSIM connects to 4G/LTE or 5G where the underlying network and your device support it. Buy before you leave, scan the QR code on arrival, and your phone is online as soon as you clear immigration.
How to activate your Thailand eSIM
Check that your phone supports eSIM—most iPhones from XS onward and recent Samsung, Google, and other Android flagships do. Buy your plan on the esimbloom site, and the QR code arrives by email within minutes. Install the eSIM before you fly by scanning the code in your phone's settings, but leave it turned off until you land.
Once you arrive in Thailand, enable the eSIM and switch on data roaming for that line. Your phone will register on the local network within a minute or two. Keep your home SIM installed if you need to receive verification codes by SMS, and choose the eSIM as your data line in your phone's settings.
Staying connected across Thailand
Bangkok, Chiang Mai, and Phuket all have strong mobile coverage in the city centers, shopping districts, and tourist zones. The BTS Skytrain, MRT, and airport rail link in Bangkok carry a signal in stations and most tunnels. Grab, Bolt, and messaging apps work reliably across the capital and major towns. Smaller islands such as Koh Lanta, Koh Tao, and Koh Phangan have coverage in the main villages and beaches, though speeds may drop in hilly or forested interior areas.
If you are traveling overland between cities or visiting national parks like Khao Yai or Doi Inthanon, expect intermittent coverage in mountain passes and remote stretches. Most travellers use 1–3 GB per week for maps, restaurant lookups, and social media. Streaming video or uploading photos in full resolution will consume data faster, so download maps offline and connect to hotel or café Wi-Fi for heavy uploads when you can.
Frequently asked questions
Do I get a Thai phone number with the eSIM?
No. esimbloom plans are data-only, so you will not receive a local phone number, cannot make voice calls, and cannot send SMS. You can use WhatsApp, LINE, or other internet-based apps for messaging and calls over your data connection.
Which Thai islands and beaches are covered?
Coverage includes Phuket, Koh Samui, Koh Phangan, Koh Tao, Krabi, Koh Lanta, and other popular islands. Signal is strongest in the main towns and beaches. Interior or very remote beaches may have weaker coverage, but most tourist areas work well.
When should I activate the eSIM?
Install the eSIM at home by scanning the QR code, but keep it turned off until you land in Thailand. Switch it on after arrival, enable data roaming for that line, and your phone will connect within a minute or two.
Can I use the eSIM in Bangkok and Chiang Mai on the same trip?
Yes. Every Thailand eSIM works nationwide, so one plan covers Bangkok, Chiang Mai, Phuket, the islands, and travel between cities. You do not need separate plans for different regions or provinces within Thailand.
How much data do I need for a week in Thailand?
Most travelers use 1–3 GB per week for maps, Grab, restaurant searches, and messaging. Streaming video or uploading photos in original quality uses more. Download offline maps and use hotel Wi-Fi for large uploads to stretch your data further.
