🐛 [firebase_auth] Firebase Phone Authentication Not Sending SMS Code

[YousefAK009]

Bug report

Describe the bug
I am encountering an issue with Firebase phone authentication where the SMS verification code is not being sent and I am receiving error code 17499. Error code 17499 indicates an internal error with the message "Error code:39".

I have already tried several troubleshooting steps such as:

• Adding my debug SHA1 and SHA256 keys to the Firebase console.
• Enabling app check.
• Registering my app with Play Integrity.
• Linking Google Play with Google Cloud.
• Adding my Google Play signing key SHA1 and SHA256 to the Firebase console.

Despite these steps, I am still facing the issue. However, using a test phone number works without any issues.

Can someone please help me resolve this issue? Any help would be greatly appreciated. Thank you.

Hi @darshankawar,
I'm sorry to bother you, but this issue is very annoying. There is still no clear solution for it.
I have published my app on the Google Play Store and released the official version. However, the SMS code issue is still present. Only test numbers are working.
I have tried many solutions, but none of them have worked.
I am not sure what else to do. I would appreciate your help in resolving this issue.
Thank you for your time.

Hi @yousefak007, is the country you're testing from in this list? https://firebase.google.com/support/faq#phone-auth-countries

Please note that not all countries are supported for phone authentication.

Hi @danagbemava-nc ,

Thanks for your response. I appreciate you taking the time to help me with this issue.

My country is Yemen, which is one of the available countries for Firebase Auth.

I tried to download the Firebase Auth example and linked it to a new account, but it didn't work. It was previously working with the Android Device Verification and SafetyNet service.
