Hi @Lazos1, at this stage we don't have offer eSIM support for Samsung Galaxy Gear devices.
To the best of my knowledge the Apple Watch series 3 is the only eSIM device supported in Aus.
Hmm, they've given you the incorrect info.
You can activate Optus Number Share if you have an eligible Optus postpaid mobile plan, Apple Watch Series 3 (GPS + Cellular) compatible iPhone & number share Bolt-on
Number Share Bolt-on: requires a compatible wearable device and mobile phone with IOS11.0 or later. Only available to customers who have/get a selected post-paid mobile phone plan and use their phone to sign-up on the app
It'll only work with a compatible handset.
It will not work with The samsung Galaxy Gear.
You must have an Apple watch and iPhone with iOS 11 or later.
