Why do GPS trackers stop working when vehicles cross international borders?

GPS trackers typically stop working at borders due to cellular network registration failures. The device's SIM card can't authenticate on the local network, often because of restrictive roaming profiles or lack of carrier agreements in specific regions. This creates 'border blackout' periods where trackers go silent during network handoffs.
