To dial home from Thailand, use the international access code 001, followed by the destination country code, area code and number you wish to dial.

For calls to Thailand, the international dial code prefix may vary depending upon the country from which the call is made, but will be followed by Thailand’s international number +66, followed by the Thai area code and local number. When dialling within Thailand, local numbers are prefixed with 0.

The main emergency number is 191 which is free to call, and is suitable for use in all types of emergency. Additional free to call numbers are 199 for fire emergencies and 1554 for an ambulance. The tourist police number is 1555.

When travelling with Haivenu, you will also always be provided with an emergency contact number to access our help and assistance.

For mobile handsets, consult your service provider in advance of departure to activate your handset for use in Thailand and seek advice concerning roaming charges, which are, however, likely to be expensive.

If your phone is unlocked, another option is to buy a SIM card locally, from one of Thailand’s many providers, the most comprehensive coverage being provided by AIS. Other major providers are DTAC and True Move. The country has wide 3G and expanding 4G coverage and signal problems are only likely to be encountered in very remote or mountainous areas. You can also purchase contract free handsets locally, though you will also need to purchase a SIM card.


Most hotels provide Wi-Fi, which is often free. In addition free Wi-Fi access is widely available in numerous public spaces throughout the country.

The 3G network is well developed, and for mobile internet, buying a SIM locally provides a relatively cheap and reliable solution, with the added advantage of access to useful navigation and sightseeing apps.

Facebook, Twitter, Instagram and YouTube are all very popular platforms in Thailand.

Political censorship and monitoring of Internet use exists in Thailand, which is most manifested by the blocking of online published material, including international news articles, deemed as critical to the Royal family and the authorities in general, and several bloggers have been arrested for their political comments.

It is therefore highly unwise to indulge in Thai political commentary, and in particular you should avoid making any comments which could be construed as disparaging to Buddhism or the Thai royalty on the internet during your visit.

Despite Thailand’s rampant sex industry, accessing online pornography is technically illegal and many such sites are blocked.


The electricity supply in Thailand is 220 Volts, at 50 HZ.

A useful visual reference guide to the full range of international plug and socket varieties can be found at, which describes the type system in use on this website.

As yet, there is no standardised socket system for Thailand, and you will likely encounter different socket systems in hotels all over the country. The majority of connections are variants of two-pin outlets, both round-pin (type C) and flat blade types (type A). Some sockets are of a three pin type suited to type B plugs, but which can also accommodate types A and C without using the ground/earth pin. In many cases, the third pin may in any case not be actually wired. Another 3 pin socket commonly encountered in Thailand is the type O round three pin outlet.

For this reason it is best either to carry a range of suitable adapters or invest in one of the new universal adapters with retractable pins which are adaptable to differing formats, particularly if you are travelling to more than one country. Usefully, some models also provide additional USB connections.

It is helpful to consider your likely needs in advance. If you will need to charge several items such as mobile phones, tablet computers, cameras etc, it may be worth bringing a multiple, preferably surge protected, outlet from your own country to avoid having to purchase several adapters, or to deal with a limited availability of wall sockets.

In most cases, if your equipment normally runs on a 110 volt, 60 HZ supply, you will additionally need a portable transformer.


Although Thailand has a traditional system of weights and measures, the model in everyday use is the international metric system based on the metre and gram.


Postal services are run by the state-operated Thailand Post, with post offices being widespread throughout the country. Opening hours fluctuate, but services are generally available from 08:00 – 16:30 on weekdays. In major urban locations some offices additionally open between 08:00 and 13:00 on Saturdays.

Thai Post services are widely considered reliable, though slow.

Several international operators, such as TNT, DHL, UPS and Federal Express, also operate in Thailand, which although expensive is best suited to items of high value.


Thailand’s time zone is GMT+7, though it should be noted for calculation purposes that Thailand does not operate a daylight saving mechanism.
