If I set up cellular with iWatch, does it use the number on my iPhone or a unique number?
Apple Watch Series 7
Additional fee, usually about $10 per month, plus the “connection fee”
Thanks. Separate device fee in relation to carrier (AT&T) or is it included in fee for the phone?
It uses your phone's number via an Esim built into the watch.
It is a separate fee. Normally about $10 a month. Check with AT&T and make sure they support it in your country/region.
