Verification SMS not being sent

I understand you're having trouble with the phone verification step during AWS account creation. This is a common issue that can occur for several reasons:

1. Phone number format: Ensure you're entering the phone number correctly, including the country code and area code.

2. Phone compatibility: Some VoIP numbers may have compatibility issues with AWS verification systems. If you're using a VoIP number, try using a standard mobile number instead.

3. Phone reception and settings: Check that your phone has good reception and that international calls are enabled on your number.

4. Origination issues: The error might indicate that AWS doesn't have the appropriate origination entities to send SMS to your region or phone type.

If you continue to experience issues, you can request manual account activation through AWS Support:

1. Go to the AWS Support console and choose "Create case"
2. Select "Account and billing support"
3. For Type, choose "Account", and for Category, select "Activation"
4. Explain your issue in the Description section
5. Select "Chat" as your contact method
6. Submit the case

An AWS support representative can then assist you with manual phone verification. They may call you directly and ask you to confirm your AWS account ID.

Remember that you can create a support case even if your account isn't fully activated yet.
