Bangkok: Expect excellent 4G and 5G coverage across the capital, especially in tourist districts like Sukhumvit, Siam, and Rattanakosin. The elevated BTS Skytrain provides continuous, strong signal. The underground MRT subway has reliable coverage on platforms and within carriages, though connections can briefly drop between some deeper stations. Indoor coverage in large malls or basements can sometimes be weaker.
Chiang Mai: The city center, particularly within the Old City moat and the popular Nimmanhaemin district, offers very reliable 4G and 5G service. However, as you travel into the surrounding mountains for treks or temple visits, like Doi Suthep, the signal will become intermittent and less dependable the further you get from the city.
Phuket: Major beach destinations like Patong, Karon, and Kata, along with Phuket Town, are well-covered with strong 4G/5G signal. Connectivity is generally reliable in populated areas. Service can become spotty in the island's hilly, jungle-covered interior, on more remote beaches, and particularly during boat trips between smaller offshore islands.
Pattaya: The city's dense tourist core, including Beach Road, Walking Street, and Jomtien, has excellent 4G and 5G connectivity built to handle large crowds. Service is generally very stable. You may experience a weaker signal while on the ferry to nearby Koh Larn, but coverage on the island itself is typically good.
Krabi: Key areas such as Krabi Town and the main tourist strip in Ao Nang have good, reliable coverage. Railay Beach, while accessible only by boat, also has service, though it can be less consistent due to the massive limestone cliffs that can block signals. The main challenge is island hopping, where you will lose signal while travelling on the water between islands.
Major Highways: Coverage is strong along Thailand's primary arteries like Route 1 (Phahonyothin) to the north, Route 2 (Mittraphap) to the northeast, and Route 4 (Phetkasem) to the south. However, you can expect intermittent signal drops in rural agricultural areas and when passing through national parks, particularly on stretches of Route 4 between Prachuap Khiri Khan and Chumphon.
State Railway of Thailand (SRT): On the main Northern, Southern, and Northeastern lines, connectivity is reliable in and around cities and towns. The signal often weakens or drops out entirely for extended periods when trains pass through remote countryside, dense jungle, or hilly terrain far from populated centers.
Northern Mountain Roads: Traveling through the mountainous northern provinces of Mae Hong Son, Nan, and parts of Chiang Mai involves frequent signal loss. Roads like the popular Mae Hong Son loop have long stretches with no service, especially in valleys and areas shaded by mountains.
Tunnels and Border Passes: Signal is typically non-existent inside longer railway tunnels, such as the Khun Tan Tunnel on the Northern Line. Similarly, expect poor to no coverage when crossing remote mountain passes, particularly along the Tenasserim Hills on the western border with Myanmar.
Remote Isan Region: While cities in the Northeastern (Isan) region like Khon Kaen and Udon Thani have excellent coverage, the vast, flat plains between them can have weak or patchy service. Signal strength can fluctuate significantly when traveling on smaller provincial roads away from the main highways.

I loved the per-country pricing model. I only paid for the countries I visited, and it was way cheaper than other eSIM providers. No hidden fees — just clear and simple.

The auto top-up feature is a lifesaver. I never have to check my balance — internet just works. And when I’m not traveling, I don’t pay. It’s fair and super convenient.

Using Bcengi TravelPass in Thailand, data on AIS networks is priced at $1.81 per gigabyte. Billing occurs per megabyte, with no mandatory daily minimum expenditure. For instance, a day with light usage, such as maps and messaging, might incur charges around $1.81, whereas a day involving significant usage like video calls will cost about $1.81.
No. The TravelPass functions as a secondary eSIM, co-existing with your present physical SIM. Your primary phone number can remain active for calls and SMS, while TravelPass provides your data services.
Yes, provided your specific device has eSIM capabilities. Models like iPhones from the XS/XR generation (2018) and newer, Google Pixel 3 and above, and Samsung Galaxy S20+ and later models are all equipped to handle eSIM. Your device must also be unlocked by its carrier. A comprehensive list can be found by consulting the compatibility page.
AIS provides reliable service across all 77 provinces and the majority of tourist locations. Connectivity is robust throughout mainland Thailand, encompassing Bangkok, Chiang Mai, Phuket, and principal roadways. However, smaller islands such as Koh Tao, Koh Lipe, and the inland regions of Koh Phangan experience restricted or intermittent service. Remote jungle zones within national parks might similarly be without signal.
For an average seven-day journey combining urban exploration and coastal relaxation, 2 to 4 GB of data is typically consumed. Travel plans heavily focused on cities, involving regular Grab usage and extensive navigation, will likely approach 4 GB; conversely, island-centric vacations featuring numerous beach days may require less than 2 GB. Considering a rate of $1.81 per GB, a weekly expenditure of $1.81 to $7.24 should be anticipated.
This varies by island. Both Phuket and Koh Samui benefit from complete network coverage. Koh Phangan offers reliable service in its primary zones, yet connectivity diminishes in its forested inland areas. On Koh Tao, fundamental coverage is restricted to the principal settlement. Koh Lipe experiences signal that is both restricted and unreliable. It is advisable to download offline maps prior to visiting any smaller islands.
While Suvarnabhumi provides complimentary WiFi, user access necessitates registration, either with a Thai mobile number or via a passport scan at a designated service counter. Connection speeds fluctuate and frequently suffer from congestion, particularly during periods of high passenger arrivals. Installing your eSIM in advance ensures you possess immediate data upon touchdown, removing any dependence on the airport's WiFi network.
Yes, Grab is compatible with international mobile numbers. The primary requirement is a stable data connection to facilitate ride bookings and monitor your driver's location. TravelPass delivers the necessary data, while your existing home number manages the verification process for your Grab account.
For the Bangkok to Chiang Mai train route, AIS network coverage is generally sustained throughout the journey. Brief signal losses should be anticipated in the rural, mountainous parts of the northern portion, though these periods are typically brief, lasting 5 to 15 minutes. It's recommended to download entertainment for your overnight trip as a safeguard.
Yes, the Bcengi TravelPass operates across numerous countries, all managed under a unified balance. Should your itinerary for Thailand involve visits to Vietnam, Cambodia, Malaysia, or Indonesia, the identical eSIM will supply data connectivity in each destination, though data rates may differ per country. There is no requirement for SIM card exchanges when crossing international boundaries.
