Vehicle Types
Low-cost anti-theft on a personal car. It wires into the vehicle, reports position over 2G, and its relay lets you cut the engine remotely from the Traxelio app after a confirmed request.
Yes, both sit in Coban's GPS103 family. The 303F is the entry wired unit; the TK303G adds an IP65 waterproof shell and a shock alarm. Traxelio reads GPS103 for either.
From the registered admin phone, change the default password first, set your carrier APN, then write the Traxelio server IP and port. The unit then reports live data instead of SMS-only replies.
Yes, while 2G stays the backbone across West Africa. It stays low-cost to source, easy to find in local markets, and simple to service. Plan a 4G upgrade only once your carrier announces a 2G shutdown for your region.
Overview
The Coban 303F is an entry-level 2G hardwired car tracker with a cut-off relay for remote engine immobilization. It speaks the GPS103 protocol that Traxelio decodes directly, so a single owner watches live position, receives movement alerts, and disables the ignition from the app · an entry-price way to add anti-theft to a personal car. Coban's 303 family became the default low-cost tracker across West Africa, and Traxelio sells and fits the 303F in Dakar.

Coban distributes a basic Android app (Coban GPS Tracker) that binds to a device by IMEI and connects to Coban's hosted server. Functional for live map and history but no driving behavior, no multi-vehicle dashboards. Traxelio replaces it with WhatsApp alerts, the Traxelio mobile app, and the web dashboard · same hardware, modern app.

The relay latched or is wired to hold. Confirm the output drives a 5-pin relay coil, not the load directly, and that Traxelio sent the resume command · the cut releases on the next ignition cycle, not instantly.
Low-signal GPS jitter. Set the movement source to ignition plus GPS rather than GPS alone so a parked car reads as stationary. Traxelio applies a default movement threshold to filter the drift.
Almost always the prepaid SIM ran out of data or credit. Put the tracker SIM on an auto-renewing M2M or data bundle so it never lapses, and confirm the APN survived any carrier reset.
