can someone explain what a sim card is and does? i recently bought my
first sim card phone; a t610 with t-mobile service. the k700i has
been released. i'd like to get it and give the t610 to my wife. i
have a *fantasy* that all i'd need to do is move the sim card from the
t610 to the k700 and poof, the k700 works, i maintain my current phone
number, service level, etc. (i don't care about preserving the
phonebook. i only have a handful of entries in the t610 right now
anyway.) tia.
