DIALING GUIDE
Follow these simple steps to dial any Thai landline or mobile number from Cambodia. The process is the same whether you're calling Bangkok, Chiang Mai, or a mobile phone.
Start by dialing the exit code for your carrier. Cambodia has carrier-specific exit codes: 001 (Telecom Cambodia), 007 (Royal Telecom), or 008 (VoIP). If you're on a mobile phone, you can simply press and hold 0 to get the + symbol, which works universally with any carrier.
001 or 007 or 008 or +
After the exit code, enter 66 โ Thailand's international country code. This routes your call into Thailand's telephone network.
001 + 66
Thai phone numbers begin with 0 when dialed domestically (e.g., 02 for Bangkok, 081 for a mobile). When calling from abroad, you must remove this leading 0.
02-213-4567 becomes 2-213-4567
Enter the remaining digits. For landlines, this includes the area code (1โ2 digits) and subscriber number (6โ7 digits). For mobiles, it's the mobile prefix plus 7 digits. A full international call should be 11โ12 digits total.

IMPORTANT RULES
Keep these rules in mind to avoid failed calls and unexpected charges when dialing Thailand from Cambodia.
Thai numbers start with 0 when dialed locally (e.g., 02, 081). When calling from Cambodia, always remove this leading 0 and replace it with the country code +66. Forgetting this is the most common reason international calls to Thailand fail.
Cambodia does not have a single universal exit code. Your exit code depends on your mobile carrier: 001 for Telecom Cambodia, 007 for Royal Telecom, or 008 for VoIP services. Using the wrong exit code may result in a failed call or higher charges. On a mobile phone, the + symbol works with any carrier.
Thai mobile numbers are 10 digits in domestic format, starting with 06, 08, or 09. When dialing from Cambodia, drop the 0 and dial 9 digits after the country code. The full international format is +66 followed by 9 digits (e.g., +66 81 234 5678).
Bangkok uses area code 2 (1 digit), while other provinces use 2-digit area codes (e.g., 53 for Chiang Mai, 76 for Phuket). After dropping the leading 0, include the full area code in your dialing sequence.
Numbers starting with 1800 or 1600 in Thailand are toll-free and typically cannot be reached from outside the country. If you need to contact a Thai business, look for their standard landline or mobile number instead.

TROUBLESHOOTING
If your call isn't connecting, check these common problems and their solutions.
Cambodia uses carrier-specific exit codes (001, 007, 008). If you use the wrong one for your SIM, the call may fail silently. Try using the + symbol on your mobile instead, which works with all Cambodian carriers.
This usually means you forgot to drop the leading 0 from the Thai number. For example, if the local number is 081-234-5678, dial +66-81-234-5678 (not +66-081-234-5678).
Thai toll-free numbers (starting with 1800 or 1600) generally cannot be dialled from outside Thailand. Look for an alternative landline or mobile number for the business you're trying to reach.
If you're calling from a rural area in Cambodia with weak signal, call quality may suffer. Using Sayfone over a Wi-Fi connection can provide more stable and clearer audio compared to a standard cellular call.
Standard international calls from Cambodian carriers can be expensive. If you're seeing high per-minute charges, consider switching to Sayfone's browser-based calling at $0.18/min to Thailand โ no SIM swap or app download needed.
