It’s understandable that in most cases, you would want to control what countries your clients can send SMS messages to. Each country and carrier has it’s own pricing and it would be difficult to create your SMS credit packages and what to price them at if your clients were sending SMS messages all over the world.
If you wanted to control this, you can by selecting the countries to give access to from your Twilio account here: https://www.twilio.com/user/account/settings/international/sms
Only select the country or countries you want your customers sending SMS messages to and uncheck all others. If a user attempts to send SMS to a country not selected, you won’t be charged and their credits won’t be deducted. It will simply be treated as a ‘failed’ message.
