Cheapest Way to Make International Calls from India
HelloAirDial (Browser-Based VoIP)
- ✅ Call USA, UK, UAE, Canada, and 200+ countries from India at local VoIP rates.

Cost Comparison: VoIP vs ISD
- Jio: ₹15 to ₹135/min depending on destination
- Airtel: ₹20 to ₹160/min
- Vi: ₹20 to ₹150/min
A 10-minute call to USA costs ₹150-1,350 via ISD but only ₹10-30 via HelloAirDial. That is 80-90% savings.
💸 Why is ISD so expensive? Carrier ISD routes your call through traditional telephone networks that charge premium rates for international connections. Calling cards are slightly cheaper but often have hidden fees, expiring credit, and inconsistent quality. International roaming is the most expensive option, often exceeding ₹150/min.
