OneNumber
You want to be always connected to friends, family, team mates, or customers.
But you don't always want to carry your phone everywhere. That's why you need OneNumber.
Turn your watch into your phone
The OneNumber Add-On lets you share your Pay Monthly mobile number with your eligible watch, so you can make calls, take calls, stream music and more for just $5 (4.35 ex. GST) a month.
Leave that phone at home!
What you'll need
To start using OneNumber, all you need is the right combination of phone, watch and plan.
Compatible phones
OneNumber works on any compatible iPhone XS or later with iOS 17.1 or later installed or Samsung phone with Android 10 or later*
Compatible watches
iPhone will need a compatible Apple Watch Series 4 or newer (GPS + Cellular) with watch 10.1 or later while a Samsung phone will need a compatible Galaxy Watch5 LTE or newer*
Eligible mobile plans
