ABSTRACT:
A communication system includes first and second radiotelephones capable of communicating with a telecommunications network. The second radiotelephone is capable of remotely acquiring at least some of the identification information of the first radiotelephone and is further capable of acquiring connection parameters from the first radiotelephone. The communication parameters may include information relating to any of: the strongest radio channel; available frequency bands; and radio channels in use. The acquired parameters are applied to effect a connection to the network, without going through channel searching procedures. This overcomes the need to physically transfer subscriber identification modules (SIMs).
