Look for the Google authenticator app on your mobile. If you can't find it you can restore your wallet from its wallet words/seed and choose not to use 2FA for your restored wallet. If you do that you will be able to send the BTC currently in your wallet without requiring the app on your mobile.

There are instructions for restoring your wallet from its wallet words/seed at this link.
