Tata Tele Business Services (TTBS) is the enterprise arm of the Tata Group and one of the most trusted VoIP service providers in Indian business connectivity. Their SmartFlo cloud telephony product offers SIP trunking, cloud PBX, toll-free numbers, and hosted IVR — backed by Tata’s nationwide fiber infrastructure and decades of telecom experience.

Grasshopper, now owned by GoDaddy, is a US-based virtual phone system designed specifically for solopreneurs, freelancers, and very small businesses that want a professional business phone number without the complexity or cost of a full VoIP platform.

It is used by over 350,000 customers globally and is particularly relevant for Indian entrepreneurs running US-facing businesses or freelancers serving international clients.

Best for: Indian solopreneurs, freelancers, and very small businesses that serve US or international clients and want a US business number forwarding to their Indian mobile. Startup founders who want to project a professional presence before investing in a full phone system.
