Tata Communications and Airtel are the two largest and most reliable enterprise internet providers in India. Both offer internet leased lines (ILL) with SLA-backed uptime, but they differ in coverage, pricing, SLA terms, and support quality. This comparison helps Indian businesses choose the right ISP for their leased line.
Yes. Many enterprise businesses in Delhi NCR use dual ISP with SD-WAN — primary Tata Communications and secondary Airtel. SD-WAN automatically fails over between links, providing near-100% uptime at reasonable cost. We design and deploy this for our clients.
Both providers typically take 3–6 weeks for new ILL installation in Delhi NCR. Airtel sometimes has shorter timelines in areas where they have dense existing infrastructure (like Gurgaon and Noida). We manage installation coordination with both providers.
