what the difference between RUIM and SIM ???

Answer Posted / syed muddassir

Hi All,
The expansion of UIM is User Identity Module
and the expansion of SIM is Subscriber Identity Module.

The major difference between Sim & Uim is :-
Sim used for GSM network whereas UIM used for CDMA network.
In simple way,Multiple network can entered in GSM, whereas
in CDMA only one is linked.. So that in CDMA the voice
clearity would be fine compare to GSM.
Hope you got it, Please correct me if iam wrong..
