how do i see my apple card credit limit?

Your credit limit was told to you when you applied and were approved. Once you add the virtual card to your Apple Wallet app on your iPhone you can see the credit limit in the Account Details in the app.

View your available Apple Card credit details or request a credit limit increase - Apple Support

If you have already setup your Apple Card in Apple Wallet, open your wallet and tap once to open your Apple Card.

Then follow the steps below (see pictures below) to see your credit limit.

Yes, I know. I posted the link to the support article. 😀😀😀
