Description
Thailand has been running on mobile data for longer than most Asian destinations — Bangkok's street-food vendors moved to PromptPay QR codes years ago, and the Grab economy from Chiang Mai to Phuket is so well-established that negotiating a fare in person now feels retro. A Blikst Thailand eSIM runs on Advanced Info Service (AIS) at 4G / 5G speeds, the country's largest carrier by coverage and reach.
Where AIS covers well
Bangkok, Chiang Mai, Chiang Rai, Phuket, Krabi, Koh Samui, Pattaya, Hua Hin, and all the major islands have 4G / 5G. The highway networks linking them have continuous 4G. The deep south (Yala, Narathiwat, Pattani) has coverage but is subject to government travel advisories — check before going. Koh Phi Phi, Koh Tao, Koh Lanta, and Koh Lipe have solid 4G on the populated beaches and thinner signal at the far northern and southern tips. Mountain treks out of Chiang Mai to Doi Inthanon National Park or Pai have 4G in towns and 3G on the passes. Khao Sok, Erawan, and Khao Yai national parks have signal near ranger stations and thin coverage in the forest interiors.
Cost vs. a local SIM
AIS, TrueMove, and DTAC all sell tourist SIMs at Suvarnabhumi (BKK), Don Mueang (DMK), Chiang Mai (CNX), and Phuket (HKT) airports. The counters are fast by regional standards (10–20 minutes) and tourist packages are aggressively priced. The case for an eSIM is convenience: load before you fly, skip the counter entirely, and have working data the moment you clear immigration. Home-carrier roaming for Thailand is typically $10/day.
Arrival at BKK, DMK, CNX, HKT, or USM
Suvarnabhumi (BKK) is the main international gateway; Don Mueang (DMK) handles most budget airlines; Chiang Mai (CNX), Phuket (HKT), and Koh Samui (USM) handle direct regional and some long-haul arrivals. Install the eSIM before leaving home. The line activates on AIS the moment your phone registers after landing. BKK's free Wi-Fi is fine but the arrivals hall walk is long — you'll want your own data before you reach the Airport Rail Link.
Apps that matter in Thailand
- Grab: Dominant ride-share and food delivery. GrabBike is the fastest way through Bangkok traffic; GrabCar is the main taxi replacement in cities.
- Bolt: A ride-share alternative, often cheaper at peak in Bangkok and Phuket.
- LINE: Used for messaging by many Thais, tour operators, and some guesthouses. WhatsApp is more common for international-run operators.
- Google Maps: Bangkok's complex skytrain (BTS), MRT, and boat routes are all mapped. Walking routes in the old city (Rattanakosin) are accurate.
- Food delivery: GrabFood, LINE MAN, and FoodPanda all operate. LINE MAN has the widest small-vendor coverage in Bangkok.
- 7-Eleven Thailand app: Ubiquitous 7-Elevens are a daily stop. The app handles loyalty and some bill payments. Tourists mostly skip it but worth knowing.
- 12Go Asia: Buses, boats, and trains between cities and islands. Works cleanly over 4G.
Island and transfer notes
Ferries between Surat Thani mainland and Koh Samui / Koh Phangan / Koh Tao have signal at both ports and weaken mid-crossing. The speedboat ride from Krabi to Phi Phi or Phi Phi to Koh Lanta has intermittent signal. Overnight trains (Bangkok to Chiang Mai on the State Railway) have coverage on most of the route except tunnel sections and remote hill stretches. Download Netflix or Spotify offline content if you're on the 12-hour overnight.
Water, weather, and scam notes
Monsoon season varies: west coast (Phuket, Krabi) from May to October; east coast (Koh Samui, Koh Phangan) from November to January. Flooded roads and cancelled speedboats are common in peak storm days — live weather matters. Scam-wise, "tourist prepaid SIMs" sold by non-official vendors outside airports sometimes don't work as advertised; sticking with AIS-branded kiosks (or an eSIM) avoids this.
Plan sizing for typical trips
A weekend in Bangkok: 2–3 GB. A one-week Bangkok + Chiang Mai classic: 5 GB. A two-week Bangkok + north + south island hop: 10 GB. A three-week full-country circuit: 20 GB. A month of remote work from Chiang Mai or Phuket: 20–50 GB. Digital nomads on longer stays (3–6 months) should consider either a local AIS SIM with long-term packages or stacking longer Blikst plans.
Install, fly into BKK, DMK, CNX, or HKT, and walk off the plane with Grab and Google Maps already live. The airport express or the tuk-tuk queue, not a SIM kiosk.

I used to have 3 mobile but the internet connection was not the best, that’s why I started to use Blikst and I find it very useful
eSIM FAQ
The Blikst Thailand eSIM runs on Advanced Info Service (AIS), the country's largest carrier by coverage and reach, at 4G and 5G speeds. AIS is well established right across Thailand, so you get fast LTE in the cities and 5G in the busier areas, with continuous 4G along the main highway networks linking the major destinations together.
Bangkok, Chiang Mai, Chiang Rai, Phuket, Krabi, Koh Samui, Pattaya, Hua Hin and the major islands all have 4G and 5G. Being honest about the gaps: Koh Phi Phi, Koh Tao, Koh Lanta and Koh Lipe have solid 4G on the populated beaches but thinner signal at the far tips. Mountain passes toward Doi Inthanon and Pai drop to 3G, and national park interiors like Khao Sok and Khao Yai are patchy away from ranger stations. The deep south (Yala, Narathiwat, Pattani) has coverage but sits under travel advisories.
Right after you buy, you receive a confirmation email with your eSIM details, so delivery takes minutes. Install it before you leave home by scanning the QR code provided, which adds the eSIM as a digital line on your phone. Activation is automatic: the line registers on AIS the moment your phone connects after you land at airports like Suvarnabhumi, Don Mueang, Chiang Mai, Phuket or Koh Samui, so you walk off the plane with data already live.
Most modern smartphones are fully compatible with Blikst eSIMs, though a few exceptions exist, so check our detailed compatibility list to confirm your device works. Your phone must also be carrier-unlocked. To check eSIM support quickly, look on an iPhone under Settings, General, About for an EID number, or check the network settings on Android. If an EID is listed, your handset can run an eSIM.
It depends on your trip. A weekend in Bangkok is comfortable on 2 to 3 GB. A one-week Bangkok and Chiang Mai classic suits about 5 GB. A two-week Bangkok, north and southern island hop is better on 10 GB, and a three-week full-country circuit on around 20 GB. A month of remote work from Chiang Mai or Phuket runs 20 to 50 GB. Maps, Grab and live weather are the main drains as you move between cities and islands.
Yes, tethering and hotspot use are supported, so you can share your connection with a laptop, tablet or a travel companion's phone. That is handy for remote work from Chiang Mai or Phuket, or for keeping a second device online during long transfers. Bear in mind that hotspotting uses your data allowance faster, so size your plan with that in mind if several devices will lean on it.
This is a data-only plan, so it does not come with a local Thai phone number for traditional calls or SMS. In practice that is rarely a problem: you can call and message over the internet using apps like WhatsApp, FaceTime, LINE or Facebook Messenger, which is how most travellers and operators communicate in Thailand anyway. Because the eSIM is a separate digital line, your physical home SIM and number can stay in the phone for anything that still needs them.
Home-carrier roaming for Thailand is typically around 10 dollars a day, which adds up fast over a trip. Local tourist SIMs from AIS, TrueMove and DTAC are sold at the airports and are aggressively priced, but you queue at a counter for 10 to 20 minutes. The eSIM's main advantage is convenience: load it before you fly, skip the kiosk entirely, and avoid the unofficial "tourist SIM" vendors outside airports that sometimes don't work as advertised.
