Is there any other way of receiving the verification code other than via SMS text message?
There are three other options apart from receiving the verification code to your regular number:
Option 1. If you have another Galaxy device that is signed in to your Samsung account, a verification code will be sent to that device via text message.
Option 2. You can also use a one-time password (OTP) app, for example, the Microsoft™ Authenticator App, to receive the verification code.
To set up an OTP app, go to your device settings, tap on your Samsung account profile image, select Security, then Two-step verification and finally tap Add OTP.
Note: If you are not able to install and run the OTP app, you may need to first register your device to the trusted device list through device settings, tapping on your Samsung account profile image, selecting Security, then Two-step verification, and finally clicking Trusted devices.
Option 3. You can use one of the backup codes that are provided when you enable Two-step verification. If you are not able to receive text messages and cannot install an OTP app, you can use a backup code.
