First, restart your iPhone.
Then, if your balance is still wrong, check the recent transactions on the payment card that you used to add money to your transit card. If you see the charge in your transaction history, the balance on your transit card might be correct, even if the balance in the Wallet app shows a different amount.
If your balance still doesn't update and you don't see the charge in your transaction history:
- On your iPhone, open the Wallet app.
- Tap your transit card and tap the More button .
- If you see the option, turn on Service Mode, then authenticate with Face ID, Touch ID, or your passcode.
- To turn off Service Mode, tap your card.
If these steps don't work, contact your transit card issuer.
