Abstract: A method and system are provided for determining the network status of a mobile device. A wireless connection between the mobile device and a wireless packet data communication network is established. The mobile device sends a data packet through the network and monitors for a response via the network one or more times within a period or until a response via the network is received. If no response is received via the network, a test message is sent to a dummy server a predetermined number of times within a period or until a response from the dummy server is received. Upon determining that a response from the dummy server has been received, the mobile device deactivates or blocks network access requests originating from the mobile device to the network, unless initiated by a user of the mobile device.

Abstract: Systems and methods for APN-based DNS query resolution for wireless data networks are disclosed. Some implementations include receiving a domain name system (DNS) query for a domain name from a device having a source IP address, the DNS query being associated with an access point name, determining whether the source IP address is within a predetermined IP address range, upon determining the source IP address is within the predetermined IP address range, updating the DNS query to include an updated domain name unique to the predetermined IP address range, forwarding the updated DNS query to a DNS server for resolution, receiving an IP address corresponding to the updated DNS query from the DNS server, the IP address being different from an IP address associated with the DNS query, and providing the device with the IP address corresponding to the updated DNS query.
