Abstract: A server, terminal device, and a non-transitory data storage medium for supporting wireless terminal devices of a cellular network for implementing program updates are described. The server includes a memory, a processor which receives instructions from the memory for execution, programs utilized in the wireless terminal devices, a receiver, and a transmitter. The receiver is configured to receive a message from a wireless terminal device requesting installation of a program to the wireless terminal device. The installation is caused by a change of an activated use profile of the wireless terminal device to another use profile, when the wireless terminal device is in an operating state with power on. The activated use profile and the another use profile include dissimilar lists of programs required in certain use situations of a user. The transmitter is configured to send the program to the wireless terminal device as an over-the-air message.
