Have a look at the AT commands for the unit. You will find the document on the Telit web site.

hi all...

i solved this problem.. Actually it needs external power which i have supplied +5v Dc ,1amp current.

Now its working fine.The main thing is that when we are connecting a antenna to the module its needs more power because antenna has some resistance, for which voltage drop occurs. By providing some external power it overcame.

hope this will helpful for others.
