Airtel, in association with Comviva, is planning to launch Virtual Phone Numbers in India. This technology enables subscribers to use upto 10 different numbers on a single phone. The software will be embedded in the SIM (Subscriber Identity Module) card itself. This is expected to be launched in another 2 months.
Comviva has already tied up with MTN of South Africa and launched the multiple SIM in Cameroon and has acquired 30,000 new users as a result.
The technology requires the user to dial a given number from the specific mobile phone and activate the SIM though a password. Once that is done, the user can receive and make calls and even recharge the account through a pre-paid coupon.
The technology dramatically reduces the cost of ownership for a mobile connection and would also be useful as community phones in villages. The cheapest branded mobile costs at least Rs 1,000. [source]
