There is none. Subscriber details are not physically removable from
the phone. It is possible to read out and re-write these details, but
this is not something that subscribers are meant to be able to do.

DoCoMo's 3G 'FOMA' phones use a smart card called a 'UIM' (User
Identification Module).

There's an 'R-UIM' (Removable User Identiification Module) smart card
system, but this is not part of the basic standards for CDMA
telephony. I don't know which networks, if any, are using it.
