A mobile communications device includes a communication subsystem operable to conduct a plurality of wireless data connections between the mobile communications device and a wireless network wherein each of the data connections is associated with a connected application operating on the mobile communications device. A processor, coupled to the communication subsystem, is configured to process requests for new wireless data connections for a plurality of applications, releasing existing data connections and establishing new wireless data connections between the mobile communications device and a wireless network. The mobile communications device also includes means for prompting a user of the mobile communications device for releasing at least one application having an existing wireless data connection upon determining that a further wireless data connection cannot be effected when a request for a new wireless data connection for an application is received.
