Smart Wearable Solution

Children's Watches, Watches for Older Adults, and a Standalone eSIM

Children's watches and watches for older adults have to connect without a phone. A children's watch handles calls, location, SOS, and a geofence, and a parent watches from an app. A watch for an older adult handles health monitoring, fall detection, SOS, and care from family at a distance. These devices cannot lean on a phone hotspot. They need an eSIM or an IoT SIM of their own. The Ministry of Industry and Information Technology is pushing eSIM use, and all three major operators support wearables with either a separate number or one number shared across two devices.

Data use splits by product. A children's watch uses about 50–150 MB a month, for location reports, calls, and data sync. A watch for an older adult uses about 30–100 MB, for health data, location, and SOS. A sports watch uses about 30–80 MB, for activity tracks, health data, and OTA. Devices sold abroad need global roaming. SimtoLink's international IoT coverage spans 200+ countries, which is what an export brand needs on the connection.

Each wearable uses 30–200 MB a month, spent mainly on health and activity reports, OTA updates, and standalone use on children's watches and watches for older adults. SimtoLink supplies eSIM and IoT SIMs, a data pool, and APIs into a health cloud, with multi-operator coverage and global roaming. Those watches need either a number of their own or one number shared across two devices, which means a connection to the operator's eSIM platform. The same feed can reach a health platform, a fitness app, and a family-care platform, so the data and the service stay together.
