What is a Cambodia virtual phone number?

A Cambodian virtual phone number is a real Cambodia DID delivered over SIP. Phnom Penh uses 23; Siem Reap 63; Sihanoukville 34; Battambang 53. Mobile numbers begin with 1, 6, 7, or 8. Cambodia is regulated by TRC (Telecommunication Regulator of Cambodia).

TRC requires KYC for foreign customers. Activation is 10-15 business days. Cambodia's market has limited operator competition resulting in higher wholesale pricing.
