Dear NowSMS Team,

We are facing an issue with SMS sender trying to generate send out SMS to country phone number that does not our customers. How can we block on NowSMS by country code?

Thank you,
Best regards,


The easiest way to do this is to define the “allowed” prefixes in your SMSC definition.

The example below shows the settings.

“Use for any outbound messages” should be turned off.

“Outbound Routing Prefix List” should contain a list of allowed prefixes to route via this SMSC.

Messages that do not match the prefix list on any SMSC connection will fail to send.
