Can networks determine what phone is using sim card?

[toady2k1]

Can networks actually tell what phone is being used to use the sim card?
Like, does the imsi number for example,contain this sort of information.

or is it purely stored seperately in imei

thanks in advance!!

yes the network identify by sim and imei nr.

if a phone is stolen the sim and imei are both blocked
leaving both of them unable to be used on the network
and any network in corporation with it

so does the sim nr that gets sent to network say what phone its using, like 'Hey im in an omnia' or the numbers seperate?

i know att distinguishes just fine...within a few minutes of switching sim card to another phone, their corporate website register the type of phone the sim is inserted into. ofc, the phone must be charged and powered on...

what r u up to anyways!?

well, got mugged on holiday, but had taken sim card out to use phone on plane. Consequently used my sim in mates phone, but know some insurance companies wont replace phone if sim wasnt in it (absolutely daft imo), so wondewring if i claimed wehther theyd be able to tell if id put sim into another phone.
