TailSim does not offer truly unlimited data plans for India. The plans that contain “Unlimited” in their name actually provide a fixed amount of high‑speed data – 2 GB per day for the specified validity, after which the speed is throttled to 512 kbps.
TailSim provides fixed data plans that give larger, uninterrupted data allowances. Examples include the 50 GB plan valid for 30 days, the 20 GB plan also valid for 30 days, and the 10 GB plan for 30 days. These options can be more cost‑effective for travelers who need substantial data, and smaller fixed plans such as 5 GB for 30 days or 3 GB for 15 days are also available.
