Why not more than one number on a SIM?
I am wondering why are they are not giving more than one Phone Number for a single SIM card?
From what I understand, your number is just what they have in backend. It is nothing to do with the communication between you and your cell phone tower.
So they can give multiple number and any call to any number will be redirected to same call phone. Is it not possible? Hey any tele-communication guys over here?
If it is already existing, then I think I would have had at least 3 numbers.
- One for family
- One for business
- One for social
Not only me, I think crores of people in this country will need more than one number. As of now they have to carry these many phones or buy Dual SIM phones.
Telephone operators can change more money for the existing resources they are giving. Just software change, and get some millions.

But in that case mobile manufactures should give free software upgrades even for low cost phones. Otherwise I have to buy a new phone to switch of my Social Mobile Number, to prevent my girlfriends disturbing me in working hours:)
Not required.
All you need is a small app Client side or Server side provided by the carrier. It does not have to be supported by device manufacturer. That app will allow you to enable, disable the various numbers and based on time.
