A portable communications device ( 2 ) and method is disclosed wherein data can be transferred between the portable communications device ( 2 ) and another portable communications device ( 4 ) through a first network ( 12 ) using a first network address. It is determined whether a condition related to the operation of the portable communications device ( 2 ) is above a minimum requirement, e.g. battery charge. Information is collected that is required for resuming the data transfer through an second network ( 14 ) using a second network address different from the first network address. The data transfer is allowed through the first network ( 12 ) if the condition is satisfied and delayed if the condition is not satisfied. If it is delayed the data transfer may be resumed later through the second network ( 14 ), e.g. via a synchronization interface and a host computer. |
