Connecting to self made CDMA Network without SIM using CDMA Modem
 

Hi Guys
I have a question which maybe sounds weird.
I want to know is it possible to use a CDMA modem in my PC to connect to a self made CDMA network without SIM!.
well the point of this question is I don't want to use sim/
For example a GSM phone can call SOS numbers even when there is no SIM on it?
Let's think I made my own BTS, and WCDMA network and now want to push my CDMA modem to connect to that CDMA network without inserting Simcard into my device. Is it possible?
If yes what is the requirement?:)
