    SIM cards are (supposedly) the same chips as smartcards (like the
    european EMV bank cards). I know bank cards have processers (this is
    how the PIN is verified by the card).

    What am I missing? I thought the chips differed in content only.

    The GSM providers (AT&T and T-Mobile) use SIM cards for identifying
    I think you meant to say is GSM providers strictly use the SIM for
    /billing/.

    Strictly speaking, GSM providers can ID someone using either the SIM
    or the IMEI, no? An IMEI won't have a person associated with it as it
    sits on the store shelf, but as soon as someone buys it and starts
    using it, there are a variety of ways an identity can become
    associated with the IMEI.

    IMEIs are usually printed the box the phone ships in, and sometimes
    eventually on store invoices.. so if you buy the phone with a bank
    card, your identity is immediately connected to the IMEI.

    Even google snags the IMEI number, and links it to your google account
    if it's an android. In fact, any Android app with the "read phone
    state and identity" permission can harvest the IMEI.
    IMEI is GSM-only, btw.
