Babu, who previously cycled through the by-lanes of this rapidly developing suburb, frequently entering into arguments with security guards of the numerous housing societies there, life is a lot more comfortable now.
Now, he takes calls on his cell phone sitting comfortable in his tiny shed that has newspapers stacked in neat rows.
"I am happy because earlier I used to cover only five societies, but with the phone I am doing ten societies now. People call me on the phone and I have no problem with the security guards as they are instructed to let me in, says Babu with a smile.

Gurmeet Singh, who operates a shop in the Gaffar Market, says the market is prone to fluctuations and the resale price is much less. "If you want to sell your two-month-old handset, it may fetch you only 30 per cent of the original cost," he says.

Sunil, a vegetable vendor, says, "I have purchased a second hand mobile from the Grey market in Karol Bagh for Rs 800 because I can't afford a new one. My mobile has lifetime validity. Now I take delivery orders on my mobile and it made my life a bit easy."
When mobile phone services were introduced in India in 1994, only the very rich could afford the handsets along with the service. But soon competition intensified in the telecommunications sector, private businesses challenged the government-owned telecommunications companes, and prices fell.
