will the i watch work for metro pcs iphones
Looking into buying a I watch but will it be compatible for a metro pcs iPhone and service?
Depends on what specific Apple Watch you are referring to, and what you mean by compatible exactly.
Metro PCs does not at this time support the Wifi + Cellular Series 3 Apple Watch on their cellular service, so the LTE portion of that particular watch will not work with Metro PCS cell network.
However, the other non cellular features of it and all other wifi only watches will work with supported iPhones running iOS 11 regardless of cell carrier the iPhone is using.
