michal_kovac Hello!
You write that on id.wialon.net you have an ID 864894030680046, then you need to enter it in the unit settings in the application.
In most cases, such devices really have ID 0 + 11 of the last IMEI digits, but sometimes all 15 IMEI digits are sent by tracker. If 15 digits was determined on id.wialon.net, then you need to enter them.
If there is any misunderstanding, please attach a screenshot where we can see how the tracker was identified on id.wialon.net.
