Hi! I understand you're having trouble setting up your TAP Air Portugal account due to a phone number error. Let me gather a bit more information so I can assist you better:

- What exact error message are you seeing when you enter your phone number?
- Are you entering the phone number with the correct country code format? (For example, +1 for US numbers)
- Is this happening during verification, like when sending a code to your phone?
- Are you using the official TAP Air Portugal app or website for account setup?

Once I know these details, I can guide you step by step to fix this phone number issue. Meanwhile, a common tip is to double-check the phone number format—make sure to include the plus sign (+) and country code without extra spaces or special characters.

Could you tell me a bit more about what you're experiencing?

After phone number is entered with +1 for USA, unable to continue

Thanks for letting me know you're entering the phone number with +1 for the USA but still can't continue. Let's try some troubleshooting steps tailored for your iPhone on iOS 18.6.2:

1. Double-check the phone number format: Make sure you enter your phone number starting with +1, followed immediately by the 10-digit number without spaces or special characters. For example: +12345678901.

2. Clear the app cache or data: If using the TAP Air Portugal app, try closing the app completely (swipe up from the bottom and swipe the app away), then reopen it and try again.

3. Try using the mobile website instead: Since sometimes app errors occur, open Safari on your iPhone and go to the official TAP Air Portugal website (https://www.flytap.com/en-us/), and attempt account setup there.

4. Check for app updates: Visit the App Store, search for TAP Air Portugal, and ensure you have the latest version installed.

5. Restart your iPhone: A simple restart may fix temporary glitches.

If after these steps the issue persists, the problem might relate to server-side validation errors or account setup bugs. In this case, contacting TAP Air Portugal’s USA customer service can provide direct support. Their USA number is 1 (800) 903-7914 where agents can assist with account setup issues.
