I want to develop SMS gateway application, SMS request (text) is sent by users to SQL server from windows applications or automatically by row insert trigger, then a dedicated mobile phone checks for rows insert on same server every 1 minute for example, once new row found it sends the message and mark progress field according to send result, i.e. sent ok, failed, no enough credit ... etc.
is it possible to keep this mobile application always up?
what library should I use? does it limit number of sent SMS (regardless GSM operator rules)
I already developed SMS gateway by VB.NET and GSM serial modem, but I believe that B4A will be mush more powerful with no more serial port communication hassle.
