Thanks for the details. I understand that the "base" will not need to be a
cell phone. The mobile will be a laptop attached to a cell phone (or similar
hardware) to send/receive messages.
What hardware is needed on the mobile side? Does it depend on the cellular
provider - is that the primary factor? For what type of hardware should I
ask available providers? An of course if there an API that Delphi can use to
send in real-time and be notified when a message is received in real-time?
I know it is dependent on the provider, but with this setup what is the
general cost per message sent/received by the mobile device? I will be
transmitting basically small changed records as plain text.
I appreciate your help with this very much. SMS messaging seems perfect for
this application.
