Mobile number, when surrendered or permanently disconnected, may be re-allocated by the TSP to a new customer after 90 days. But many service delivery
platforms/ systems are not updated by the earlier customer, who may either not be using the service regularly and hence do not find a reason to update his mobile
number, or due to lack of awareness of potential danger due to mobile number reuse, thus creating huge potential of an identity/profile take over on re-allocation of
a mobile number.
