keep europe rental zone active

Thank you for describing your issue. It seems you're experiencing some confusion regarding AWS regions and SMS sending. Let me clarify a few points:

1. The region you see when you log into the AWS Management Console (in your case, us-east-1) is not necessarily related to your physical location or the region you need to use for specific services.

2. For sending SMS messages to Switzerland, you are correct that you need to use the eu-central-1 (Frankfurt) region. This is the closest AWS region to Switzerland that supports SMS functionality.

3. You don't need to delete other regions or keep only eu-central-1. AWS allows you to use multiple regions for different purposes.

To resolve your issue:

1. When you need to send SMS messages, make sure you switch to the eu-central-1 region in the AWS Management Console.

2. You can set eu-central-1 as your default region in the AWS Management Console settings to avoid having to switch manually each time.

3. If you're using AWS SDKs or CLI for sending SMS, ensure you're specifying eu-central-1 as the region in your configuration or commands.

Remember, you can use different regions for different services without conflict. The important thing is to use eu-central-1 specifically for your SMS sending to Switzerland. You don't need to delete or deactivate other regions.

Hello.

Please try setting the default region for the management console using the steps in the document below.
If you set this, the region you set will be displayed first when you sign in.
