Hi all.
I’ve placed an order for the Fastrack Supreme GSM/GPRS Modem.
However, it’s going to take quite a while for it to arrive.
Meanwhile, i’ve written an application in Visual Basic 2008 to send/receive SMS messages.
I need to test the application ASAP to see if it works since i have quite a tight deadline.
Is there a Wavecom GSM/GPRS Modem emulator or a virtual GSM/GPRS Modem that i can use to test my application?
Many Thanks.

Why?
What’s the holdup?
These things should be available ex-stock!

Not that I know of.
However, the commands for sending/receiving SMS are pretty standard across all GSM modems - so can you just find a substitute that is immediately available?
Can’t your distributor lend you something?
