The tools are included in the GSMmap-live system, which auto-submits data for analysis at

Actively collect 2G and 3G traces using Samsung Android phones.


  • Samsung Galaxy S2 / S3 phone


  • Pre-compiled .apk TODO
  • Source Code TODO


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.

Second, your phone will send SMS short messages via an invalid SMS-C to an invalid number.

During our tests (in Europe) we have not encounter any network that would charge for these transactions. However, we can not rule out that you may be charged in specific settings.

To control for involuntary charges, we strongly advise the use of a dedicated pre-paid SIM card for these tests.
