SIM INSTALLING
To use the Vega MT-5 CAN GNSS tracker, you need a nano-SIM with support of SMS and GPRS
functions. There must be cash on the account. PIN protection must be disabled.
The device supports the ability to use two SIM cards. In this case, one of them will perform the reserve
function, and will be used only if it is not possible to send data from the first main SIM.
The devices have their own algorithm for SIM-card switching from main to reserve and back:
1)
The device cannot join to the network for the 5 minutes while it operates with main or reserve SIM-
card;
2)
If 16 unsuccessful attempts were made to establish a TCP connection to each server (not disabled
in the settings);
3)
If a TCP connection is established, but there is no data at the application level from the servers for
the 5 minutes.
The location of the primary and secondary SIM slots is shown in the figure below, the primary slot is
highlighted in red.
