While receiving SMS Messages on my TE through Nokia 5110, some times I am getting strings like <!+BP> or <!+01> at the end of message, for e.g.

Hello world + <!+BP>

So can some one exaplain why <!+BP> or <!+01> is coming?
Is the originating carrer adding this to the message?

This is urgent.
I am here in New Delhi, INDIA. If some AIRTEL guy is reading this, please let me know if Airtel is adding this.
