The "Virtual Mobile" solution brings high performance with low message latency using our +44 country Virtual Mobile Numbers. A single number allows an application to receive incoming SMS from all UK networks, and all other supported networks worldwide. The Virtual Mobile Numbers behave in the same manner as a regular mobile number, but with the benefit of significantly higher throughput (20-50 SMS per second) to your application. Virtual Mobile Numbers are compatible with each of our supported interfaces - SMPP, HTTP and SMTP (email) as described in the Sending SMS section. A diagram of a virtual mobile number in operation is available here. Please note that Virtual Mobile Numbers can also be termed MSISDN numbers or long numbers. Timestamp: When using the SMPP interface and certain VMN ranges that we provide, the exact time the SMS was sent by the mobile subscriber can be received.
