### Answer
 

Currently, SMS capabilities are available for Retell Twilio numbers and your own Twilio numbers [(1) ](<https://docs.retellai.com/deploy/enable-sms>) . Telnyx is not supported yet . For other custom telephony providers, you'll need to check your provider's documentation on how to enable SMS .

Current SMS capabilities are limited to US numbers only .
