eSIM subscription
Carriers and regions that support the eSIM/VoLTE
service
The watch supports the eSIM service (One Number service and Standalone Number service).
To ensure better call experience and continue to support normal call service even when
3G network is unavailable, it is recommended that you contact your carrier to enable
VoLTE.
• eSIM One Number service: This service allows you to add your watch as an eSIM auxiliary
device (supplementary card) of your phone (primary card) and enables your watch to share
your phone's number, voice plan, and data plan. You will then be able to make calls and
access the Internet on your watch.
• eSIM Standalone Number service: This service gives your watch a standalone number and
abilities to access a cellular network on its own. Your watch will have an independent tari
package with allowances for SMS messages, calls, and data. You'll then be able to make
calls, send/receive SMS messages, and access the Internet phone-free, directly on your
watch.
