Tata Communications and Airtel are the two dominant internet leased line (ILL) providers for Indian businesses. Both offer guaranteed bandwidth, uptime SLAs, and dedicated support. This comparison helps IT managers choose the right ISP for their office connectivity.
Most ISPs including Tata and Airtel offer leased lines starting from 2 Mbps (guaranteed, symmetric). The practical minimum for a 10-person office doing video calls is 10 Mbps. For offices with Zoom/Teams + cloud apps, we recommend at least 50–100 Mbps.
Metro cities (Delhi, Mumbai, Bengaluru): 2–4 weeks. Tier 2 cities: 4–8 weeks. The provisioning time depends on last-mile infrastructure — if the building has existing fibre, it's faster. We handle ISP coordination as part of our connectivity services.
Yes — we commonly deploy dual-ISP setups using Tata as primary and Airtel as secondary (or vice versa), with an SD-WAN or firewall managing failover. This provides genuine redundancy since Tata and Airtel have different submarine cable and last-mile infrastructure.
