What is ASK (Asynchronous Server Kernel)?
The Asynchronous Server Kernel (ASK) enables customers to access wireless services using asynchronous messaging like SMS, Email or 2-way pagers. This means that your applications can be used by the vast majority of mobile devices that are capable to send SMS messages but are not internet-enabled. You ask for the service by sending a short message. You then receive a message in reply. You can now interactively run the same applications through asynchronous devices that you ran from synchronous devices (such as WAP phones, PDAs, or browsers).
