Samsung Gear S3 Frontier LTE and eSIM: what to know

The Gear S3 Frontier LTE is a Tizen smartwatch from 2016. Its LTE version has an embedded SIM, but that SIM is provisioned by mobile carriers for their own smartwatch plans. We cannot confirm that it accepts a separate travel eSIM profile, so please don't assume it does.

Where to look: where a plan is available, it is managed through the Samsung Gear / Galaxy Wearable app on the paired phone rather than in the watch's own Settings.
EID: this watch does not reliably show an EID. Ask your carrier or Samsung support instead of guessing.
Before you travel: ask your carrier whether the watch's plan works abroad and whether it accepts other profiles.
Bluetooth fallback: without mobile data of its own, the watch still syncs with your phone over Bluetooth.

The most reliable option abroad is to install an eSIM Prime travel eSIM on your eSIM-compatible phone before the trip and activate it on arrival. Your main number and WhatsApp stay available, and the watch can stay paired with the phone.
