Definition
UBI (Usage-Based Insurance) is a car insurance model that dynamically prices based on the vehicle's actual usage intensity and driving risk characteristics. Common dimensions include mileage, time distribution, frequency of rapid acceleration and deceleration, proportion of speeding, lateral acceleration during turns, and exposure time on high-risk roads. After the popularization of connected vehicles, OEM T-Box or aftermarket OBD devices can upload behavior characteristics to insurance companies or actuarial platforms at a minute-level or trip-level granularity via IoT SIM cards, replacing traditional questionnaires and self-reported mileage, and improving risk differentiation and anti-fraud capabilities.
Reporting driving behavior emphasizes data contracts: which signals come from CAN, which from GNSS, and which from a mobile companion app, need to be labeled with source and confidence in the schema; reporting frequency should balance model refresh delay and radio cost, usually using a combined mode of "end-of-trip batch + real-time abnormal events." Personal sensitive trajectories need to be anonymized or gridded before being exposed to the public network. SimtoLink can configure an independent APN and directional data pool for insurance joint innovation projects, separating premium simulation from vehicle owner service traffic to reduce mutual interference and billing disputes.
Technical Features
Actuarial models need to handle device loss and vehicle replacement scenarios: ICCID changes and vehicle transfer score inheritance rules need to be clearly defined. Weak cellular networks may cause incomplete trip slices, and the platform must tolerate gaps and correct them using statistical methods. When interfacing with regulatory reporting, discount factors, exemption clauses, and data collection scope must be auditable. For anti-fraud purposes, mileage can be cross-checked with external data such as gas station POS and highway gantries, but additional authorization is required. For fleet insurance, an aggregated risk index rather than single-vehicle details can be output to protect the relationship between employer and drivers.
In operations, patterns such as "long periods of zero reporting" and "abnormally frequent heartbeats" should be monitored to identify device removal or SIM misuse. When linked with the claims process, behavioral data from a few seconds before a collision can help determine responsibility, but storage cycles and access permissions must be strictly controlled.
Use Cases
Applicable to UBI pilots offered with the first maintenance service of new energy vehicles, rideshare driver operational insurance, and mileage-based insurance for young drivers. Implementation is recommended in three phases: shadow period for observation without pricing, comparison period running alongside traditional policies, and full rollout incorporating pricing factors. SimtoLink IoT SIM cards and usage transparency capabilities provide connection-side support for UBI scaling.
Key points for cooperation with IoT SIM cards
Configure directional data and separate billing accounts exclusively for insurance companies, and account for automaker value-added services and insurance reporting separately; when the card is silent or device and card are separated, the scoring pipeline should flag decreased data reliability and trigger manual sampling. Vehicles operating across provinces need to declare roaming tariff limits in advance to prevent drivers accepting long-distance trips from causing abnormal connection costs that affect premium calculations. When interfacing with third-party actuarial clouds, TLS and fixed exit IPs should be prioritized to ensure long-term firewall stability. After claim closure, travel detail retention periods can be shortened according to regulations, retaining only aggregated scores for renewal reference, and reviewed alongside IoT SIM card log retention policies.
