No way to activate Apple Card without iPhone or other apple device
This is pretty much the dumbest thing I've ever encountered. I even talked to Apple Support and Goldman Sachs support. There is no way to activate the card without an Apple device.
Correct. The Apple Card must be requested using an iPhone. It can only be activated on device. Otherwise, you have only a line of credit at the Apple Store. Apple Card is designed as an extension of the iPhone.
