Voice pricing: India
At today’s rate (~₹83/$), Twilio’s India outbound rate converts to approximately ₹1.83/min for mobile. Vobiz’s ₹0.45/min is roughly 4× cheaper on the same route. The gap is real and consistent — Twilio’s pricing is set for global averages, not India-first economics.
Twilio’s pricing page publishes these rates in USD. They change with FX rates even if Twilio doesn’t update them. Vobiz rates are fixed in INR.
Phone number pricing
Twilio does not offer India 140-series numbers. This is a hard blocker for businesses running outbound A2P calls in India — TRAI requires the 140 series for all business outbound calling, and you cannot use a standard DID for A2P outbound. Vobiz provisions 140-series numbers with TRAI compliance.
SMS pricing
India’s DLT system (TRAI) requires SMS senders to register on the DLT platform with their telemarketer ID, sender IDs, and message templates. Twilio does not handle DLT registration — you manage it independently. Vobiz provides guidance and support for DLT setup.
Setup and onboarding
Both platforms are developer-friendly and self-serve. Twilio has significantly more documentation volume and community answers, which matters for edge cases. Vobiz has India-specific documentation and a team that understands TRAI regulations.
AI voice agent support
For AI voice agent deployments, both platforms support the core technical requirements. The India 140-series gap is critical: if you’re running AI outbound calling in India, Twilio cannot provision the number series you need.
Compliance
For regulated industries in India (BFSI, healthcare) that need data residency, neither platform has a standard India-region offering — contact both for custom arrangements.
Total cost comparison: 1 lakh minutes/month
A company doing 100,000 minutes/month of outbound voice to India mobiles:
The gap widens further when you factor in GST input credit (recoverable on INR invoices from Indian entities) and the cost of FX conversion.
When Twilio makes sense over Vobiz
Twilio is the right choice when:- You have an existing Twilio integration and migration cost exceeds the savings
- You need Twilio-specific features (Verify, Conversations, Studio) that aren’t replicated elsewhere
- You are calling primarily US, UK, or Western Europe — Twilio’s pricing on those routes is competitive
- You need the breadth of Twilio’s global community and support resources for a complex custom integration
- Your billing entity is outside India and USD invoicing is preferable
When Vobiz makes sense over Twilio
Vobiz is the right choice when:- You are calling primarily Indian numbers (mobile or landline)
- You need India 140-series numbers for TRAI-compliant A2P outbound
- You need INR billing and GST invoices for your India entity
- You are building an AI voice agent for India and need a telephony layer that understands local compliance
- You want to reduce telephony cost on India routes without changing your AI orchestration layer
Migrating from Twilio to Vobiz
The migration is mechanical — Vobiz uses the same SIP and XML concepts as Twilio (with minor differences). Key steps:- Create a Vobiz account and get equivalent phone numbers
- Translate your TwiML webhooks to Vobiz XML (most verbs are equivalent)
- Update your AMD parameter names (
machine_detectionvs Twilio’sMachineDetection) - Test on a staging number before cutover
- Port your Twilio numbers to Vobiz if needed
