Does the eSIM also work on the Thai islands such as Koh Samui or Koh Phi Phi?

Largely yes. The most visited islands, such as Koh Samui, Koh Phangan, Koh Lanta and Koh Phi Phi have acceptable 4G coverage in inhabited areas and along the main beaches. In the most remote areas or in secluded coves the signal may weaken, but in village centres and resorts the connection is generally solid.

Do I need an adapter to charge my phone in Thailand?

Yes. Thailand uses Type A, B, C and O sockets at 220V. Italian plugs (Type C or L) may not fit in every accommodation without a universal adapter. Before leaving, check you have one in your luggage: it is a small purchase that avoids headaches from the very first check-in.

Can I use the eSIM on trips in northern Thailand, towards Chiang Rai or the Golden Triangle?

Yes, in the cities and along the main roads of the north the 4G signal from AIS and TrueMove H is present and stable. In the most remote mountainous border areas, such as some tribal villages near Myanmar, coverage may be reduced. For treks in the mountain forests, it is advisable to download offline maps before leaving your base.

How much does roaming with an Italian SIM cost in Thailand?

Thailand does not fall under the European 'roam like at home' regulation, so roaming costs with an Italian SIM can be very high — often €5–15 per day, or pay-as-you-go rates with limited data bundles. A Datiovunque eSIM dedicated to Thailand is almost always cheaper and guarantees a stable connection for the whole trip.

Is the eSIM active in Bangkok traffic, on canal boats and on night trains?

Yes. Bangkok has some of the best urban coverage in Southeast Asia: the BTS metro, the elevated MRT trains, canals and river ferries are all served by the 4G signal. Even on night trains to the north or the south, coverage is good along the main railway corridors, with possible interruptions only on the most rural stretches.

How much does an eSIM for Thailand cost?

eSIM plans for Thailand start from €1.69. You pay once for the amount of data you choose — no subscription, no monthly fees and no hidden roaming charges. Plans with more data or longer validity cost more.

Which operator or network does the eSIM use in Thailand?

The eSIM in Thailand connects automatically to local networks such as AIS, TrueMove H, True Corporation (incl. DTAC), National Telecom (NT) — on 4G/LTE and, where available, 5G. Coverage reaches about 90% in inhabited areas. Your phone picks the best available network by itself.

Can I keep my Italian number with the eSIM in Thailand?

Yes. Your Italian SIM and number stay active — the travel eSIM works alongside it as a data-only line. You stay reachable on WhatsApp, iMessage or Wi-Fi while you use the local network to browse. Traditional calls and SMS still go through your Italian number.

Should I activate the eSIM before or after I leave?

Install the eSIM at home, on Wi-Fi, before you leave. The data plan then activates automatically when you connect in Thailand. That way you are online as soon as you arrive, without looking for airport Wi-Fi or buying a local SIM.

Can I top up or renew the plan for Thailand?

Yes. When the data runs out or the validity expires, just buy a new plan — the eSIM profile already installed is kept and does not need to be installed again. You stay connected without interruption.

Can I share the connection (hotspot) in Thailand?

Yes. You can share the connection in Thailand through a personal hotspot with a computer, tablet or other devices. Shared data is deducted from your plan, so allow a few extra gigabytes if you expect to use the hotspot often.

How many GB do I need for Thailand?

For a normal trip, 1–3 GB a week is enough for maps, messages and occasional browsing. With social media and photo sharing allow about 5 GB; for streaming, video calls or a hotspot count on 10 GB or more. If the volume is not enough, you can buy an additional plan at any time.

Thailand is a slap to the senses, in the best possible way: the fragrant chaos of Bangkok's night markets, the golden temples of Chiang Mai wrapped in the morning haze, the emerald waters of Koh Lanta where the signal will surprise you with its solidity. Getting around here without internet means losing the tuk-tuk you booked at the last second, failing to find the beach bar hidden among the palms or giving up on translating a street food menu written only in Thai. The distance from Italy is real — over 9,000 kilometres — and having a reliable connection from the first moment, without stopping at the counters at Suvarnabhumi airport, is the first smart move of the trip. With Datiovunque, you are already online before you even land.

Why an eSIM is essential in Thailand

Thailand can seem an easy country for tourists — and in many ways it is — but connectivity tells a more nuanced story. Physical SIMs are sold at airports and in 7-Eleven stores, it is true, but you have to show your passport, fill in forms and often wait, which eats into the first precious moments of the trip. With a Datiovunque eSIM set up before leaving Rome, the problem does not exist. The local operators AIS, TrueMove H and DTAC cover about 90% of the national territory with 4G/LTE networks, and 5G in urban areas: Bangkok, Pattaya, Phuket and Chiang Mai enjoy excellent signal. Many tourist islands such as Koh Samui, Koh Phangan and Koh Phi Phi are also well covered, although some remote beach areas may have a weaker signal. Thailand is at UTC+7, which is 5 hours ahead of Rome in summer and 6 in winter: having working internet from the very first moment lets you tell people back home straight away, without having to look for a congested public Wi-Fi in the arrivals area.

Going away for 1-2 weeks? Pick a plan with 3-5 GB for maps, photos and messages.

Business travellers

For video conferencing and email while travelling, we suggest at least 5 GB or an unlimited plan.

A longer trip is better served by 10+ GB, or by a regional plan that spans multiple countries.
