Questions about AI calling and WhatsApp costs
How much does an AI phone call cost per minute in India?
With Plivo for the line, Sarvam for the voice and OpenAI as the AI, a one-minute call works out to roughly ₹6 to ₹7: about ₹0.38 for the call, ₹1.35 for the voice and around ₹5 for the AI. The cheapest combination in the calculator comes to a little over ₹2. The AI line is an estimate until you measure it on test calls.
Are the prices in this calculator live?
No. Each third-party price was read from that provider's own published price list on 17 September 2026. Providers can change their prices at any time, so check the provider's page before you fix a budget. The calculator shows the date on every result.
Does Convo360 add a margin on calls or messages?
No. You connect your own Plivo, Sarvam, OpenAI, Gemini and Meta accounts and each of them bills you directly. Convo360 charges a flat plan fee, ₹999 a month for WhatsApp or ₹2,999 a month with AI calling, plus GST, with nothing per message or per minute.
Which lines are estimates and why?
The AI lines. OpenAI, Google and Anthropic charge per token, not per minute, so the cost depends on how long your instructions are and how much is said on each call. The calculator assumes a typical call and marks those lines as estimates. Ten test calls on your own script give the real figure.
Which voice is best for Hindi and other Indian languages?
Sarvam's voices are made for Indian languages and are priced in rupees, so they are the usual starting point. ElevenLabs Multilingual is an alternative at a higher price. Always listen on a real phone call in your callers' language before you decide, because price is only half the choice.
What does WhatsApp cost per message in India?
Meta charges ₹0.8631 for each delivered marketing template and ₹0.115 for each utility or authentication template. Replies to customers are free for the first 1,000 a month per number and ₹0.115 each after that. These are Meta's India rates as published on 17 September 2026.
Is GST included?
GST at 18% is added to the Convo360 plan and to Plivo's charges, and you can switch the plan GST off. Taxes charged by Sarvam, OpenAI, Google, ElevenLabs, Twilio and Meta are not included, because their price pages do not all state them. Treat those as extra where applicable.
