Just saw this advertisement on today's newspaper



Look at the reality , at every nook and corner of the city SIM Cards are being sold for as low as Rs 100 ( USD 1.55) millions of them have been sold this way are the Telephone companies stupid enough to close millions of accounts ? beside the ad is outdated , is InstaPhone still operational ?

Another question how mobile companies will know that the details are not correct to block the SIM

Questionly
