Understand partial SMS call-flow

Points: 25

A drug dealer is using your network to receive a password on its cellphone from a partner-in-crime abroad. This password gives access to a special wallet used for money-laundering within the criminal organization. Within the international roaming traffic present in the pcap, use this password as a flag. Beware that lots of SMS have been sent to the dealer in order to mask the real message.

The dealer's IMSI: 208010000057409
MSISDN of the partner abroad: 39612379125
