You don't receive the SMS code

The verify screen counts down 30 seconds before Resend code becomes tappable. Wait for it, then request a new code — and use the newest one, because an older code no longer works.

Check your number first

Go back one screen and check the country code and the number. A number entered with the wrong country code will look valid and still never receive anything.

Delivery speed depends on your mobile operator, so give a fresh code a minute before requesting another.

What the error messages mean

• Incorrect code — the digits don’t match the most recent code. If you requested several, only the last one counts.
• Code expired — request a new one; codes are only valid for a short while.
• Too many attempts — verification is temporarily blocked. Wait a few minutes, then request a fresh code.

Still nothing

Sign in with Google or Apple instead. It’s the same account only if you used that method before, so if your account was created with a phone number, keep trying the code — switching methods would create a second, empty account.
