Some tests were carried out using a Data bundle plan and Blackberry Internet Service for a Service provider - Airtel Nigeria on Symbian Nokia 500, Android Galaxy Pocket and Blackberry 9780.
On each instance the device would take ages before it sent an sms heratbeat, after which the target would not send any other heartbeat to the agent - No matter the actions carried out on the device to prompt it.
Even changes to the configuration of the Trojan/ Emergency configuration never get sent/delivered to the target.
We would like to know whether any development could be done to get around the peculiarities of Network providers in Nigeria, especially Airtel.
