Came across this very handy web-app that owes its inspiration to the ongoing 2G Scam case. The Supreme Court recently cancelled licenses, to provide 2G services, of a host of mobile service providers operating in India, deciding fraudulent means had been used in acquiring them. Thus, mobile numbers that the service providers had allotted to consumers on acquisition of license are likely to become inoperable.
Using this app, you can very easily verify if your mobile number would be amongst those that would be affected. India mobile status compares your cellphone number, that you enter, with Mobile number pattern in use in India & then once it determines the service provider & the circle of operation, it compares it with the list of cancelled licenses, then telling you if your number is affected or not.
