This tip is about activating the friends and family (FNF) plan in BSNL mobile. Applicable to only the residents of India.
According to this plan u can call to any two numbers, of your choice, at a rate of 10ps per minute. The following are the conditions.
1) Both the numbers should be BSNL numbers.
2) One number should be a landline number and other should be mobile number.
3) You can change the numbers after 6 months.
Just do the following:
Send FFE <space> <land phone number> <space> <mobile number> to 53733
The method is same for both activation and changing the numbers. (Change possible only after 6 months)
Happy talking.... :)
