What does a 2G or 3G switch-off do to a tracker?
A tracker sends its position over a mobile network through a SIM card. When an operator switches off a network, a device whose modem can only use that network can no longer connect. It stops sending position, events and video, and the vehicle can vanish from your platform with nothing wrong on the vehicle.
Devices that also support 4G may carry on, but only if their settings and the SIM plan allow it. Check each model, and do not assume.
Getting the dates
Shutdown dates differ by country and by operator, and they change. This file states none. Ask every operator whose SIM cards you use, in writing, and keep the notice. The carrier log records the date, the regions, the source and who confirmed it.
- Ask which networks and regions. 2G, 3G or both, and whether the switch-off comes in stages.
- Ask about your SIM plan. Roaming and IoT SIM plans may follow different rules.
- File the answer. Write the source and the date you received it next to the date.
Tracom does not supply or confirm network shutdown dates for any country. Your operator, or your telecom regulator, is the source.
Setting priorities
You cannot replace everything in a day. Score each vehicle on five questions: contract need, safety use, how near the operator's date is, weak 4G coverage on its routes, and value. The total gives a priority.
A
Score 7 to 10
- Typical case
- Contract, safety or a near date
- When
- First batches
B
Score 4 to 6
- Typical case
- Important, date not close
- When
- Middle batches
C
Score 0 to 3
- Typical case
- Low use, easy cover
- When
- Last batches
Typical bands. Set your own.
Budget
Total = A + B + C + reserveIllustration: 10 x (100 + 20 + 5 + 0) = 1,250Illustrative figures in units of your currency. They are not prices. Take real figures from your supplier's quote.
After each swap
- Confirm that position, ignition and your inputs arrive on the platform.
- Link the new IMEI to the right vehicle and keep the vehicle's history with it.
- Copy the report interval, alerts, geofences, panic button and driver ID settings.
- Test cameras if the vehicle has an MDVR.
- Log the old device and deactivate or reassign the old SIM.
Limits of this file
It is a planning tool. It does not know your operator's plans, your devices' network support or your costs. You enter those. It does not change anything on a device.
