How Virtual SMS Works?

Virtual SMS number, also called a Long Code is a channel through which SMS messages from any mobile phone can be received by an application. These messages can then be subject to various business logic, depending on application needs. Virtual SMS numbers are similar to any other valid mobile telephone number. In contrast to Short Codes (which are usually 4-6 digits long), long numbers are 10-12 digits long (depending on the country).
