Frequently Asked Questions
Is Bluetooth fitted to every GV350MG?
The linked brochure marks BLE 5.0 as optional. Confirm the supplied hardware revision, Bluetooth support and firmware; do not assume support from the model family alone.
Does GV350MG use NB1 or NB2?
The linked device brochure specifies Cat M1/NB1. The newer Queclink catalogue lists Cat M1/NB2 for the family. Confirm the actual radio revision and supported bands for the units and operator before deployment.
Is GV350MG the same as GV350CEU with a different modem?
No. GV350MG has two RS232 ports and a different housing and interface layout. GV350CEU uses LTE Cat 1, one RS232 port and BLE 5.2 in its linked datasheet. Verify the full specification for either model.
Can it read CAN data from a tractor or heavy truck?
It supports CAN 2.0A/B and J1939, and the manufacturer describes configurable CAN integrations. Confirm the vehicle, required data, wiring, firmware and platform decoding; support is not universal.
Can I replace a GV300 just by changing the SIM?
A migration requires a compatible GV350MG unit plus checks of the harness, accessories, radio service, SIM provisioning, firmware and platform protocol. A SIM change alone does not upgrade GV300 hardware to LTE.
Can I order GV350MG in bulk?
