Question

Can I send SMS to roaming numbers?

Applies To

• Vonage SMS API
• Outbound SMS
• Roaming Numbers

Answer

SMS delivery to roaming numbers cannot be guaranteed, as this depends on the interconnection agreements between the two carriers.

If the subscriber's home network has roaming agreements with networks in the current location, SMS will be most likely delivered. In this scenario, roaming should rarely have any impact in SMS Sender ID and character-set support, so it can be expected that Sender ID and correct display will occur.
