### Answer I'm sorry to hear about your Twilio account issue. Here are your options for getting SMS capability through Retell AI: Option 1: Purchase a Retell Twilio Number You can purchase a number directly from Retell and enable SMS capabilities on it. [(1) ]() However, the SMS approval process requires: - Business profile approval (free) - Brand registration ($4 for low-volume or $45 for standard) - SMS campaign approval ($15 one-time fee) This process can take around 2-3 weeks as it's a manual review process on the telephony provider side. Option 2: Use Telnyx via SIP Trunking You can integrate with Telnyx as an alternative telephony provider via elastic SIP trunking for voice calls. [(2) ]() However, for SMS specifically, Telnyx is not supported yet through Retell. [(1) ]() You would need to check Telnyx's own documentation for SMS capabilities outside of Retell. Important Limitation Current SMS capabilities through Retell AI are limited to US numbers only. Fastest Path Forward Unfortunately, there isn't a "fast" way to get SMS working through Retell since the approval process takes 2-3 weeks regardless of which path you choose. If you need SMS urgently, you may need to resolve your Twilio account issue directly with Twilio or use a separate SMS provider outside of Retell for the time being.
