A GPRS test can only be performed if a GPRS-enabled SIM is inserted into the GSM
Signal Analyser.
There are 2 different GPRS tests that can be performed:
1. The
1
st
(applicable to any GPRS-enabled SIM) is a test to determine whether the unit
can attach to the GPRS network from that location/base station.
For any GPRS enabled SIM, select 'Internet' from the GPRS menu and press
Pass/Fail indicates if the GSM Signal Analyser could successful attach or not.
2. The
2
nd
(applicable only to certain UK SIMs) is a test to determine whether the unit
can initiate a GPRS session on that particular network. Select the relevant APN for the
SIM and press
Note
: If a CSL Dualcom SIM is used, connection to their VPN may be checked by
selecting VPN as the APN.
A pass indicates successful GPRS session on the particular network has been opened. A fail
indicates the unit was unable to start a GPRS session from that location/base station.
