https://community.ee.co.uk/t5/Apple-Devices/Apple-Watch-plan-not-working/m-p/1609894#M159109 <P>I recently bought a used Apple Watch Series 7 with cellular and I wanted to set up a mobile plan for it so I bought a ee sim (£15 subscription pack) and I activated it. I went to set up cellular on the watch app and it kept saying “unable to configure mobile plan”. I tried multiple time already and I even cleared previous plans in the watch app to see if that was the problem but it kept saying the same thing.</P> Sun, 29 Mar 2026 20:38:05 GMT Ciprian230212 2026-03-29T20:38:05Z https://community.ee.co.uk/t5/Apple-Devices/Apple-Watch-plan-not-working/m-p/1609894#M159109 <P>I recently bought a used Apple Watch Series 7 with cellular and I wanted to set up a mobile plan for it so I bought a ee sim (£15 subscription pack) and I activated it.

It must be paired with a mobile contract.</P> Sun, 29 Mar 2026 20:56:00 GMT https://community.ee.co.uk/t5/Apple-Devices/Apple-Watch-plan-not-working/m-p/1609895#M159110 XRaySpeX 2026-03-29T20:56:00Z
