> What if you could make calls on Reliance to only Reliance folks? Or what if Airtel charged you Rs. 20/min for calls to Docomo, but Rs 1/min to calls on Airtel?
What if Facebook gave everybody in India free phones and free calling, even if it was only on Facebook phones? Would anyone have to be the errand boy for their neighbors' calls?
I don't see how your experience where most could not afford any access (let alone restricted access) to basic telephony applies to this scenario where a restricted service is being given for free.
(I also spent my childhood vacations in rural areas where our house was the only one with a phone for miles around. And even then they would trouble us only for issues of some urgency. I have a hard time believing any of the people who'd walk all the way over would prefer doing that over getting a free but restricted phone service.)
