Direct customer vs. reseller customer - what's the difference?
Signing up at tracker.6xcom.com vs. a reseller's own branded subdomain.
Signing up directly with 6X
If you register at tracker.6xcom.com itself, you're a direct 6X customer - you see 6X's own branding, and you pay 6X directly for your vehicle subscriptions.
Signing up through a reseller
If you register at a reseller's own subdomain or domain, you're that reseller's customer - you see their branding, their support contact, and you pay them directly (their own price, their own bank account) for your vehicle subscriptions.
Either way, the actual tracking features - live map, trip history, geofences, alert rules, driver assignment - work exactly the same.
If you also use 6X AutoDiag or 6X Charge
If you add a vehicle's VIN and it matches a diagnosis report on 6X AutoDiag, or its plate number matches a vehicle on 6X Charge, your vehicle's edit page shows a quiet note that a match exists - just a count, never the other product's actual records, since those are separate accounts.
