I have a 45mm Cellular Series 7 watch purchased in the US. It will not connect to my home UK cellular network because the LTE frequencies used in the US are different to those in rest of world. The US model number is A2477 The Europe model number is A2478 I’m trying to discover what parts differ between these two models and whether it would be feasible to swap the parts (antenna I guess?) to get my watch to use my home cellular network. Does anyone have any experience of doing this?
Your issue is the modem within the SIP unit. Sadly, it’s not replaceable.
