Smartwatch plans
The cheapest smartwatch plan tracked by OpenStream is Optus's Optus Number Share at $5.00 a month, which requires Eligible Optus postpaid mobile plan and a compatible phone; 4 plans from 3 carriers were compared on 2026-11-08.
A cellular watch needs a plan from the same carrier as the phone it pairs with, and the carriers only sell the add-on on some of their own phone plans. The price below is the add-on; the phone plan it requires is listed beside it and is the larger cost. Resellers (Boost, amaysim, Kogan and the rest) generally do not offer a watch add-on; a reseller that does will appear here once its page is read.
