Number Share: What you need to know

Number Share lets you share one Mobile Phone number on the Optus network between a compatible connected wearable device and a Mobile Phone. This means that you can make / receive calls and use data on your wearable device even if you don't take your Mobile Phone out with you.

Calls and data made from the wearable device can be seen on your bill under the one number once Number Share is active. We'll send you data usage alerts for the total data used on both devices.

The Apple Watch GPS + Cellular and Samsung Galaxy Watch (Cellular) are currently the only devices that support the Number Share feature and use the eSIM technology.

To check if your mobile number is eligible, go to optus.com.au/esim/check.

 

How eSIM works

Unlike a traditional SIM card, an eSIM (embedded SIM) is built into a device (e.g. Smart Watch) that allows for an independent connection to our Mobile network.

A compatible connected wearable device is not the same as a Mobile Phone. Some network functionality is not available on these devices, call quality may not be the same standard as a Mobile Phone and may drop out in certain areas. It does not support the LTE 700MHz spectrum (which is one of our 4G spectrums) and calls may drop out when you move from 4G to 3G coverage areas whilst on a call.
