1. What an insurance device sends over cellular
Smart insurance covers auto insurance, UBI driving behavior, loss assessment, and health insurance. OBD units, in-vehicle devices, and loss-assessment terminals report over 4G. SimtoLink supplies 4G to insurers, with a data pool, financial-grade security, and an API into the core insurance system.
2. Policies, photos, rescue, and wearables
The work covers auto cover, UBI, and loss assessment. Bandwidth and the security bar differ by job:
Auto insurance OBD and UBI
An OBD unit reports driving behavior and mileage over 4G, for UBI pricing, incident alerts, and renewal reminders.
Loss assessment and image recognition
A loss-assessment terminal uploads accident photos and video over 4G, for AI assessment, remote verification, and faster claims.
Rescue and dispatch
Rescue equipment reports location and status over 4G, for dispatch, track backhaul, and response-time control.
Health cover and wearables
A smart band reports health data over 4G, for health management, chronic-disease cover, and activity incentives.
3. What the insurance link has to cover
- UBI driving data: OBD units keep uploading acceleration, braking, and GPS tracks. The link has to stay up, and mileage has to be measured accurately.
- Loss-assessment images: Accident photos and video have to go up quickly. AI recognition needs a high-definition image, so the 4G link needs more bandwidth.
- Financial-grade security: Insurance data covers money and privacy. It needs PCI DSS, a private APN, TLS 1.2+ encryption, and an IP allowlist.
- Coverage across the country: Vehicles are insured nationwide. More than one operator has to cover the gaps, or the SIM has to switch networks, so signal holds in remote areas.
- API into the core system: Exchange data live with the UBI platform and the core insurance system, and push claim status and alerts by webhook.
4. Which SIM fits which device
Network, bandwidth, and power draw differ by line of business, so the SIM follows the device and the job. Use the table as a starting point:
| Use | Recommended network | Why it fits |
|---|---|---|
| Auto OBD and UBI devices | 4G | Continuous driving data, mileage, and incident alerts |
| Loss-assessment and claims terminals | 4G | Accident photos and video, AI assessment, and remote verification |
| Health-insurance wearables | NB-IoT/4G | Infrequent health reports and chronic-disease monitoring |
5. How much data an insurance device uses
One device typically uses about 20–200MB a month, mostly data reports. Pool SIMs by line of business, keep 20%–30% spare, and encrypt at financial grade.
6. Security for policy and claim data
Treat the link as extremely high security. Insurance covers money and privacy, so it needs PCI DSS, TLS 1.2+, a private APN, and an IP allowlist. SimtoLink provides financial-grade protection and completes real-name registration for the SIMs.
7. What SimtoLink would put on the devices
For connected-vehicle OBD, UBI boxes, and loss-assessment terminals, use a 4G IoT SIM. Auto insurance has to collect driving data as it happens, and loss assessment has to upload photos. SimtoLink plans for 99.9% network availability, a data pool, and an API into the core insurance system and the UBI platform.
8. Taking a book of business live
Walk an insurance rollout through these stages:
Pick the SIM by line of business and device, and check coverage on the vehicles and at the sites. Set a private APN and an IP allowlist, and alert at 80% of the data allowance. SimtoLink stays with the project from the first pilot through the national book. Contact us for a plan built around those devices.
