Why get a Cambodia (+855) number

Southeast Asia is one of the most mobile-heavy regions on earth, and chat apps are where most customer conversations start.

With a +855 number you can serve Cambodian customers, suppliers and partners without opening an office in Phnom Penh, and without asking anyone to pay for an international call.

Because it's a real number on the Cambodia telephone network, it works for normal calls and text messages — including one-time passcodes and verification SMS from apps and websites.

What's included with every Cambodia number

Receive as many SMS as you like — codes, alerts, replies
Send up to 500 texts a month
Call out for up to 1,000 minutes a month
Take unlimited calls from Cambodia and abroad
Plug into Zoiper, Linphone, 3CX or Asterisk with SIP
Forward calls to your own mobile
Dial from the browser — nothing to install
No contract; keep the number as long as you want

Works with WhatsApp, Facebook, Google, Telegram and more

Your Cambodia number receives the one-time codes and verification calls sent by WhatsApp, WhatsApp Business, Telegram, Signal, Instagram, Facebook, Google, Gmail and thousands of other services, so you can register or recover a Cambodia account from anywhere.

And you're covered: if an app you need doesn't accept your number, our 7-day replacement guarantee swaps it for a new number free — or you get a full refund if it hasn't been used.

Looking for a Cambodia virtual number?

Most people searching for a Cambodia virtual number want a +855 number they can use online, without a SIM card or a trip to Cambodia. Smart Messaging gives you exactly that — but on a real number from the Cambodia numbering plan, not an app-only line or a shared list.

You use it in your dashboard, in any SIP app or forwarded to your own phone, and it receives standard SMS and voice calls — which is why WhatsApp, Telegram, Google and Facebook verification codes arrive like on any mobile line. Read more: virtual number vs real mobile number.
