Hello!

My SIM900 module is working normally, but when I setting AT+CREG=1 and restart, it is freeze.

The status led is freeze one moment, after the modem is not function.

Why?

Sorry my bad english :D
 

It may be due to power supply. When it is registering to network and its need more current. So please Check your power supply.
 

actually it's because of power
your power can not support module in power up & registering in network & it's down check voltage in start up in module
 

i need AT command to auto answer a voice call,i am using sim900A.
ATSO dosnt seem to work.
thx.
