Koh Chang Banks
In White Sand Beach, Krung Thai (opposite the mini Pattaya bar zone) is the last of the high street banks still operating on Koh Chang. Normal hours are 08.30 to 16.30, Monday to Friday.
The Government Savings Bank (GSB/Omsin) has a currency exchange, with its branch in Klong Prao opposite the 1st big 7-11 just before the temple, 09.00 to 16.00. Baac in Klong Son has an exchange too.
You will fnd ATMs all over the island except Bang Bao Beach (Klong Goi), Salak Khok and Chek Bae. There are also currency exchange kiosks in all the major beach areas.
Koh Kood and Koh Mak do have ATMs. Some resorts on both of those islands do offer cash off credit cards for 3% to 5%.
Banks in Koh Chang buy dollars but are reluctant to sell them, so if you are going to Cambodia and need dollars, then ask around in shops and resorts local to you, change money over in Trat or take baht.
Koh Chang Mobile Phones
Mobile telephone coverage is excellent across the island, with both 3G, 4G and 5G available. Using your own phone is not a problem, but it will be very expensive.
If international roaming is turned on, the phone is constantly connected to the data network, meaning astronomical bills are run up in a very short space of time. Check with your carrier before you leave for the best tariff and when in Thailand, switch international roaming off when not needed and use the wifi connection for your internet.
Check too with your own carrier on their international policies as you may be able to register Thailand as your favourite country (of 2 or 3 countries in a 6 month period) and then you can simply use your own package.
Thai SIMs
It’s easy to get tourist SIMs on arrival, normally for 30 days or E-sims which you use in conjunction with your own SIM.
Companies include Dtac (Happy), AIS (12Call) and True Move. As you emerge from Customs in Arrivals Level 2 Suvarnabhumi Airport, you’ll find them all in a line. The prices range from 50bt to 300bt for the card, with all sorts of different options, packages and credits. You can also get them in 7-11s.
In all cases, you need to register your passport details so remember to bring it with you.
International Calling
You can use dial-around numbers, which work with either your own sim or with a new sim as above, see the respective companies websites (which have English translations) for details. AIS, for example, uses 00500 + country code + city code + number with rates at 5bt to 10bt a minute.
The dialing code from Thailand is 001 + country code + city code (dropping the zero) + number. To Thailand, it is 00 66 or +66 + city code (dropping the zero) + number. Area codes for Bangkok are 02, for Trat and Koh Chang, 039. Most mobile numbers begin 08 or 06.
Emergency Repairs
For mobile repairs and advice, try either of the shops, TS-Mobile opposite Lotus’s (after the temple) in Klong Prao or Alpha, same side of the street, about another 500 metres further on.
Koh Chang Internet
Koh Chang has fiber optic internet, with speeds up to 100Mbps/30Mbps but not all places will have upgraded from the older ADSL. Almost every resort has WiFi in the common areas and inside your rooms, but connections and speeds, even in the luxury spots, can be poor.
For printing (5bt to 10bt a sheet for b/w, with colour maybe double) and passport photos, head to Baansin 8 which is just after the Koh Chang Tennis Club, down the small soi opposite Klong Prao temple.
