To load a ticket, I have to choose between my Navigo card, my phone or my connected watch.
On the application Purchase screen, you need to choose the device on which the ticket will be loaded: Navigo card OR mobile phone OR connected watch.
Tickets on the Navigo card, tickets on the phone and tickets on the connected watch are not synchronised. With Île-de-France Mobilités application, you can transfer your tickets from one Android phone to another.
