What Is a Virtual Number?
A virtual number, often known as a second line or cloud-based phone number, is not linked to a certain device or SIM card. It doesn’t use the phone network to make calls and send messages. Instead, it uses Voice over Internet Protocol (VoIP) technology. This flexibility is perfect for people who work from home, businesses, and anyone who wants to keep work and personal communications separate without having to carry two phones.
