SnoopSnitch is an Android app that collects and analyzes mobile radio data to make you aware of your mobile network security and to warn

you about threats like fake base stations (IMSI catchers), user tracking and over-the-air updates. With SnoopSnitch you can use the data collected in the GSM Security Map at gsmmap.org and contribute your own data to GSM Map.

The tests include an active part. First, your phone will place outgoing calls to a dedicated number. This number will always be busy and never answer in order to rule out voice charges as best as we can.
51
52 5 Alex
Second, your phone will send SMS short messages to an invalid number.
53
54
In some cases, we saw operators charging for these kind of transactions transactions. Hence, please have an eye on your phone bill when performing active tests using SnoopSnitch.
55 2 Alex
56
To control for involuntary charges, we strongly advise the use of a dedicated pre-paid SIM card for these tests.
