  • (a) sending, by the mobile device through a cellular network or a hotspot network to the cellular network, an authentication request for establishing an Internet Protocol (IP) packet session;

    (b) receiving, by the mobile device in response to the authentication request, an IP address assigned to the mobile device from the cellular network for use by the mobile device, the IP address assigned based on a result of the authentication request;

    (c) sending, by the mobile device in response to receiving the assigned IP address, the assigned IP address to a reverse domain name system (DNS) server to perform a reverse DNS lookup of the assigned IP address;

    (d) receiving, by the mobile device from the reverse DNS server and based on the reverse DNS lookup of the assigned IP address by the reverse DNS server, a host name associated with the assigned IP address;

    (e) determining, by the mobile device, whether redirection of the mobile device to a platform of the cellular network for activation of the mobile device is to occur based on the IP address assigned to the mobile device from the cellular network for use by the mobile device bydetermining that the redirection is to occur if the assigned IP address is a restricted IP address that causes the reverse DNS lookup to obtain a restricted host name from the reverse DNS server, anddetermining that the redirection is not to occur if the assigned IP address is a non-restricted IP address that causes the reverse DNS lookup to obtain a non-restricted host name from the reverse DNS server; and

    (f) redirecting, by the mobile device in response to an IP communication request provided by a user of the mobile device and only if it is determined that the redirection is to occur, an IP session of the mobile device from the user'"'"'s requested web server identified in the IP communication request to the platform of the cellular network.
