Abstract: There is provided a method in a first communications device operable to communicate with a second device using a network supporting first and second different communication methods. The method comprises: allowing the first device to communicate with the second device using the first communication method; registering the first device on a service platform of the network; requesting from the service platform a second device status indicator of the ability of the second device to communicate using the second communication method; receiving the second device status indicator from the service platform; and, allowing the first device to communicate with the second device using the second communication method in dependence on the received second device status indicator. The second device status indicator depends on the current network connectivity of the second device. At least one of the first and second devices is a mobile telecommunications device.
