### Answer
International Web Chat & SMS:
Based on the available sources, Retell AI supports multilingual capabilities across over 31 languages for web chat [(1) ](
) , which enables international users to communicate effectively. The platform has expanded multilingual support to include English, Spanish, French, German, Hindi, Russian, Portuguese, Japanese, Italian, Dutch, Romanian, Danish, Finnish, Greek, Indonesian, Norwegian, Slovak, Swedish, Bulgarian, and Hungarian [(2) ](
) .
For SMS to international numbers, the documentation discusses SMS setup primarily for US numbers through A2P 10DLC registration [(3) ](
) . International SMS capabilities aren't explicitly detailed in the available sources for sending to international numbers outside the US.
Gemini S2S Model:
I don't have information in the available sources about when access to the newest Gemini speech-to-speech (S2S) model will be available on Retell AI. The sources mention that Claude and Gemini models have undergone deprecation and automatic migration to newer versions (as of 5/25/2026) [(4) ](
) , but don't specify details about upcoming S2S Gemini model releases.
For the most current information about upcoming model releases and international SMS capabilities, I'd recommend checking:
