Hi

In old SIM300 , when I would like to get SMS :
AT+CMGF=1
AT+CMGR=1
It works fine.

And now in new SIM900.
When I call AT+CMGR=1 and there is no SMS in memory - work fine.
When I call AT+CMGR=1 and there is SMS - a have the restart modem.

What is wrong ?
 

Check the module's firmware version and consider upgrading it, the sim900 is under development.
 


Please send me the code for reading sms please.........I have stucked (zgulkhan@yahoo.com).
