Is there anything wrong getting a Certified Refurbished Apple Watch?
Experience with refurbished Apple Watches?
Can't activate cellular on refurbished Apple watch
Which one is yours?
GPS + Cellular versions:
A2725 40mm, A2724 44mm (International);
A2726 40mm, A2727 44mm (USA, LATAM, Canada);
A2855 40mm, A2856 44mm (China, Hong Kong)
Visible (from the internet, not sure if it is accurate):
LTE / 5G (DSS) Bands: 2, 4, 13.
5G Bands: n261 (2800 GHz), n260 (3900 GHz).
Maybe... you have a cellular version that does not work on Visible?
For instance, China uses (from internet search):
4G Bands: B3 (1800 MHz), B8 (900 MHz), B40 (2300 MHz), B41 (2500 MHz)
5G Bands: n78 (3500 MHz)
not sure if this could be the issue, but I hope it helps...
If you managed to pair it to your iPhone, I don't see how this could be related to activation lock, maybe someone else can share some light.
