In order to recover your wallet, you should have your recovery/backup phrase with you and ready to use.
As a non-custodial wallet, your Abra wallet is held privately on your phone. Our company never has access to your funds, or the associated recovery phrase. Thus if you lose your recovery phrase, you are at risk of losing all funds in the corresponding Abra wallet.
Users are strongly advised to write down their recovery phrase, and store it in a secured location, to avoid losing access to their funds.
