The GSM Security Map at gsmmap.org compares the protection capabilities of mobile networks. This app collects data and adds it to GSM Map.
This application currently only works on Samsung S2 and S3 devices and requires root priviliges during the mobile network data capture
- Samsung Galaxy S2 or S3 phone
- Samsung stock firmware
Note: Custom Android systems like Cyanogenmod are not supported!
- Root privileges on phone, e.g., via Framaroot
- Pre-compiled .apk
- Pre-compiled .apk from Google Play Store
- Source Code:
git clone https://opensource.srlabs.de:/git/gsmmap-android.git
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.
