I have a Navigo Liberté + contract and a Navigo Annual Pass on my phone. How do you know which one will be used?

On an iPhone, the Navigo Annual Pass will be loaded into a new dematerialized card, different from the one where your Navigo Liberté + contract is loaded.

Also, you recommend that you select "by default" the card in which your Navigo Annual Pass is loaded so that it can be used as a priority during validation or during an inspection and thus avoid having to manually select the card at each validation or having validated journeys and therefore invoiced on the Navigo Liberté + contract.

See the activation of Express mode

Conversely, if you suspend or cancel your Navigo Annual Pass, then it is recommended that you activate the card on which the Navigo Liberté + contract is loaded by default so that it takes over and your journeys are billed on it.
