1. Some advice before you begin!
= Your phone calls’ security is granted by using the VoIP data line instead of the voice one.
Under particular events, due to the VoIP network condition, it could be present a little latency.
In the presence of a WiFi internet connection, consider to use it for a better communication quality.
= As a VoIP phone call, with data-packet exchanging, both the caller and the called pay for the calling.
To save your money consider to subscribe an unlimited mobile internet data plan with your mobile
operator.
= When making a secure call, before being connected to your contact, the system needs to exchange
and verify the security keys. It takes a while, so you need to wait some seconds before starting the
conversation.

party must be running PrivateGSM soft-
ware and be connected to the Internet.

3 Receive a secure call using PrivateGSM
Once PrivateGSM is installed, you are able to receive
a secure call.
When an incoming secure call is ringing on your
phone, PrivateGSM displays a pop up.
Once in PrivateGSM, you only need to press “Accept”
to allow the connection. The system exchanges and
verifies the security keys and then the conversation
can start.
!
To receive a secure call, you must be run-
ning PrivateGSM software and be con-
nected to the Internet.
4 Call phases
To establish a call, PrivateGSM completes three phases, shown by three icons:
1. Red light: the connection is starting. This step may take several seconds.
2. Yellow light: ZRTP keys are being exchanged to secure the call.
3. Green light: secure call is established. Now it is possible to speak in a secure way.

5 Call quality level
Some factors that affect the GSM network (i.e. GPRS use, poor signal, frequent radio cell changes,
roaming), could decrease call quality, increasing voice delay. The “green light icon”, shown above,
changes to display the current quality level:
Poor connection quality.
Average connection quality.
Good connection quality.
6 Check your security
A PrivateGSM phone call is always encrypted.
When you call a contact, to verify that there are no
intrusions, PrivateGSM displays a security code, con-
sisting of two random words, to both parties.
Check the two words with your contact: if you see
the same security code, then the call is secure.
The security code is different each time you make or
receive a new secure call.

As the trial period expires, PrivateGSM turns in Re-
ceive Only mode.
In this mode PrivateGSM still allows you to receive
secure calls for as long as the software is installed on
your phone, but it’s no more possible to call other
PrivateGSM users.
