<p>The invention is directed to a digital mobile phone (1) of a type using a subscriber identification module, the improvement being that there is an externally attached holder for at least two subscriber identification modules so that either can be readily selected by a switch (13) for use in the same phone. There are also described flexible circuits (6) that are used to connect the electrical contacts (7) used conventionally for reading a subscriber identification module by the phone (1) inside the phone that are able to slip through gaps that are naturally occurring between protective covers of the phone (1) because of necessary manufacturing tolerances so that the external subscriber identification modules can be connected without prejudicing manufacturers warranties on any phone.</p> |
