Recruiting Booster 2 way SMS

Summary:

Few questions on implementing 2 way SMS using Recruiting Booster:

Is there a way to enable SMS capability for only a few countries, meaning candidates would be presented with only email option when applying and not see the phone number option?

Also, we see this new feature ‘Configure List of Countries to Send SMS Messages’. Can we get some clarification on how this feature works? When candidates select ‘Use Phone Number’ option, will they see only those countries enabled in the profile option in the drop down to enter the phone number or is it that candidates can still enter the phone number for a different country but there will be no SMS sent to that number for the country not included in the list?
