So many things wrong with this:

  1. That’s a fax machine handshake not a data modem.
  2. That’s a LOT of data to be hissing over dial-up in a highly compressed GSM voice channel. That kind of interface would be pushing it even on 10 Mbps broadband.
  3. The background noise would have had that handshake repeating over and over

    She must be hacking a government fax machine to read out the buffer and fetch the information from the ducuments in there.

    She quickly improved her phone and cracked the gsm authentication to make the phone establish multiple connections in parallel.
