I uninstalled my Android app. Do I lose my tickets that have already been purchased?

If you delete the transport application (Île-de-France Mobilités, Bonjour RATP or SNCF Connect), you will not lose your tickets because they are stored in your SIM card, or in the secure element of your phone/connected watch or in the complementary application "Mes Tickets Navigo". You need to go to Google Play to reinstall the app so that you can check out the available titles again and buy more.

If you remove the companion app, the impact on your titles depends on where they are located:

• If your tickets are stored in your SIM card or in the secure element of your phone/connected watch, uninstalling the contactless Ticket complementary application does not delete them: simply reinstall the application in order to be able to consult the available tickets again, buy new ones and validate with your phone or connected watch;
• If your tickets were stored in the My Navigo Tickets complementary application, uninstalling it or deleting its data has resulted in the loss of the tickets it contained: by reinstalling it you can continue to use the service but you will not find your tickets and they cannot be reimbursed.
