As far as we know, Queclink trackers are usually configured using a special configurator provided by the tracker manufacturer - Manage Tool.
Unfortunately, we do not have instructions for the tracker specifically QUECLICK GV320
but you can try to use the commands similar to other tracker models from this manufacturer.
Also as an example, we provide commands for setting up the cv200 tracker (cv200 is a tracker model, so if you are setting up a GV320 tracker, you should replace cv200 with gv320)
APN Setting: AT+GTBSI=cv200,,,,,,,00,,,,,,,FFFF$
Example: AT+GTBSI=cv200,omnitel,omni,omni,,,,30,,,,,,,FFFF$
Server and Port Setting: AT+GTSRI=cv200,0,,1,,0,,0,,0,0,,0,,,FFFF$

We hope this information will help you with setting up the tracker.
