What is a Virtual Phone Number?
A virtual phone number is a telephone number that is not tied to a specific phone line or SIM card. Instead, it exists in the cloud and can receive SMS messages and calls through the internet.
How Do Virtual Numbers Work?
When someone sends an SMS to your virtual number, the message is routed through telecommunications networks to our servers. We then display the message in your dashboard in real-time, typically within seconds.
