I can get other International options, but TravelPass is not available, apparently. Is this just because it's a brand new phone of is there another reason?
Travel pass is only available for Verizon phones. Your non carrier version is not eligible.
Its cheaper to buy a local SIM card aand your phone is unlocked (which is the beauty of buying and unlocked phone)
I have the Moto X Pure on Verizon. I can't add Travelpass option either. I'm currently on hold with customer rep right now. It seems like a glitch on their end.
