Understand partial SMS call-flow
A 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. In the international roaming traffic present in the pcap, flag this password. Beware that lots of SMS have been sent to the dealer in order to mask the real message.
The dealer's IMSI: 208010000055332
MSISDN of the partner abroad: 39612364911
