Troubleshooting
If you did not receive the required data during the installation, you can send several SMS commands
to your device to check what might be wrong.
6.7.1
gsminfo
Use the
gsminfo
SMS command to know if the device is connected to mobile networks and the
internet.
Command syntax:
password
gsminfo
Response example:
ST:2019.06.20 23:26:33; OP 22210,
lvl 15
, LAC 20030, CID: 28289, GSM; M:I
126, R 125, SP: 0;
GPRS 0
:
O 64,C 0, E 248; LK:O 575, E 1, TMO 126; RS: 04; P 0
The relevant parameters and their values are described in the table below.
lvl
The mobile signal level. If
lvl
is lower than 10, the signal is weak, and it is
likely that there is no connection to the network.
GPRS
The internet status. Possible values:
•
0
–
no internet connection
•
1
–
the device is connected to the internet
In the previous example, the GPRS value is 0. This would mean that the device is not connected to
the internet.
