Good to know in Thailand
Facts from official sources and the press, each with the date we last checked it.
Thai tourist SIMs: passport and a 60-day limit
Under NBTC rules published in Thailand’s Royal Gazette in August 2025, foreigners must present a valid passport to register a SIM card, and tourist SIMs are valid for at most 60 days, with no extension through top-ups; continued use requires a new registration. A Voyafi eSIM is bought online and installed on your phone, without a registration counter.
True and dtac now run as one network
After True and dtac combined, True said in December 2025 that its “One Network” project had fully integrated the two mobile networks. It puts combined 5G coverage at 94% of Thailand’s population and 4G at 99%; before integration in 2023, dtac’s 5G reached 47% and True’s 83%. The network table on this page shows which networks our Thailand plans use.
Suvarnabhumi Airport: 60 minutes of free Wi-Fi
Airports of Thailand says that at Bangkok’s Suvarnabhumi Airport you can join the network “AOT Airport Free Wi-Fi by NT”, enter an email address and accept the terms, then use the internet for 60 minutes. That is enough to install an eSIM bought in advance, although installing it before you fly is simpler.

Tourist Police: 1155
The UK government’s travel advice for Thailand lists 1155 for the Tourist Police, 191 for the police, 1669 for an ambulance and 199 for the fire service. A Voyafi eSIM is data-only and has no Thai number, so save these numbers before you travel and keep your home SIM in the phone for calls.

Thailand eSIM: common questions
- How much does an eSIM for Thailand cost?
- Plans for Thailand start at $2.34 for 1 GB valid for 7 days. The largest gives you 50 GB for 30 days at $65.79. Prices are in US dollars and are the final amount you pay.
- Which mobile networks does the Thailand eSIM use?
- In Thailand the plans run on TrueMove H, DTAC and AIS. Your phone connects to whichever is available where you are.
- Does the Thailand eSIM support 5G?
- Yes. 5G is listed for TrueMove H, DTAC and AIS. You get it where the local network has 5G coverage and your iPhone supports 5G; elsewhere the eSIM uses the fastest network available.
- Can I use the same eSIM in other countries?
- The plans on this page work in Thailand only. If your trip continues, the Asia plan covers Thailand and 19 other countries on one eSIM, from $5.42.
- When does my Thailand plan start?
- When the eSIM first connects to a network in Thailand, not when you buy it — so you can install it at home before you travel.
- Does the Thailand eSIM give me a local phone number?
- No. These plans are data-only: mobile internet, not a local phone number, and no calls or SMS. Your usual number stays on your iPhone.
- How do I buy a Thailand eSIM?
- On this website or in the Voyafi app: pick Thailand, choose a plan and pay once. You confirm your phone supports eSIM before you pay, then install the plan with one tap.
- Do I need to show a passport for a Thailand eSIM?
- Not for a Voyafi eSIM: you buy it online and install it yourself, without visiting a shop. Thai SIM cards work differently: under NBTC rules amended in May 2026, non-Thai nationals register mainly with a passport, in person at a branch or authorised dealer, and may hold at most three SIM cards per provider, according to the law firm Tilleke & Gibbins.
- Is there 5G in Thailand?
- Yes, across most populated areas. In May 2026, AIS said its 5G network covered more than 95% of Thailand’s population, with 18.5 million 5G users. The network table on this page shows whether our Thailand plans use 5G; you also need a 5G-capable phone.

Before you go
Check that your phone supports eSIM and is carrier-unlocked. You confirm this before you pay.
Install the eSIM at home over Wi-Fi. Downloading an eSIM needs an internet connection.
After you land, turn on data roaming for the travel line and select it for mobile data.
These plans are data-only: mobile internet, not a local phone number.
