How much data does a connected vehicle use per month?

A basic telematics-equipped vehicle uses 100-500 MB/month for diagnostics and navigation. With infotainment, passenger Wi-Fi, and periodic OTA updates, usage can reach 2-5 GB/month. A single large OTA software update might use 1-3 GB in one download event.

Do connected vehicle SIMs work across country borders?

Yes, this is a core requirement for automotive SIMs. Providers like Cubic Telecom and Vodafone IoT offer seamless cross-border connectivity across Europe, North America, and globally. The SIM automatically connects to local networks as the vehicle crosses borders.

What's the difference between fleet tracking and connected vehicle SIMs?

Fleet tracking focuses on GPS location and basic telemetry for logistics management. Connected vehicle SIMs support the full in-vehicle ecosystem: infotainment, OTA updates, passenger Wi-Fi, emergency calling (eCall), and advanced driver assistance. They require much higher data caps and automotive-grade reliability.

Connected vehicles represent one of the highest-value M2M SIM markets. Beyond simple fleet GPS tracking, modern vehicles require always-on connectivity for infotainment systems, over-the-air software updates, real-time diagnostics, emergency calling (eCall), and increasingly, vehicle-to-everything (V2X) communication.

Data requirements for connected vehicles are substantial. A single OTA software update can be hundreds of megabytes or even gigabytes. In-vehicle Wi-Fi hotspots may serve multiple passengers streaming content simultaneously. Even basic telematics — engine diagnostics, driver behaviour, and maintenance alerts — generates steady data flows throughout every journey.

Automotive-grade connectivity has stricter requirements than most IoT applications. SIMs must operate reliably across extreme temperature ranges (-40C to +85C), withstand vibration, and maintain connectivity across country borders as vehicles travel. The SIM must also support the full vehicle lifecycle — from factory provisioning through the 10-15 year life of the vehicle.

Key considerations for connected vehicle SIMs include: multi-country roaming for cross-border driving, automotive temperature and vibration ratings, support for eUICC/eSIM for remote provisioning, high data caps for OTA updates and infotainment, and partnerships with your vehicle platform or telematics provider.

Questions to ask any provider

1Do you support eUICC/eSIM for remote carrier provisioning and switching without physical SIM access?
2What multi-country roaming coverage do you offer for vehicles driving across national borders?
3Are your SIMs rated to automotive temperature specs (−40°C to +85°C) with vibration certification?
4What high-data plans do you offer for OTA software updates that can be several gigabytes per vehicle?
5Do you have established partnerships with automotive telematics platforms or vehicle OEMs?
6How do you manage SIM lifecycle over a 10–15 year vehicle lifespan, including network technology changes?

Common mistakes to avoid

Consumer SIM form factors — automotive SIMs must meet AECQ qualification standards for vibration and temperature extremes.
No eSIM/eUICC support — managing physical SIMs across millions of vehicles at production scale is simply not viable.
Insufficient data caps for OTA updates — a single software update can be several gigabytes per vehicle across a large fleet.
Limited international roaming — modern vehicles regularly cross national borders and connectivity must follow seamlessly.
