Code for what? Logging into Samsung? Some other account. If what's app doesn't give you notifications for texts, you can either look for the text if you know you are expecting one or use your real number. Some verification services do not like virtual numbers. Depending on which accounts you have 2FA enabled for, you should be able to set multiple verification routes: text, call, email, push notification. If you have your WhatsApp number in those accounts, the code should come through. Is your issue only with not getting the notification, or the code not coming through?
