BSNL FREE DELIVERY REPORT

For some BSNL connections delivery report is chargeable(10ps).
Here is a simple trick for free delivery report.
While typing the msg, give an exclamation mark '!' in the beginning & then type the msg.
eg: !hi
Then the recipient will get it as 'hi' without '!'
Just try it. Its working well in 944- series.
Try on other series also.
May not work while forwarding msgs.
Type from the beginning itself, i mean a fresh msg.
