Yes. EtravelSIM offers plans that advertise an unlimited data allowance for India. The “Truly Unlimited Data for India” series lists a data cap of Unlimited for each plan, with validity ranging from 1 day up to 30 days and corresponding prices. These plans are available with various validity periods (1 day, 2 days, 5 days, 7 days, 10 days, 15 days, 20 days, 30 days) and carry a price that increases with the length of validity.
Other plans with “Unlimited” in the name, such as the “India eSIM Unlimited – 7 Days”, “India eSIM Unlimited – 14 Days” and “India eSIM Unlimited – 30 Days”, show a data allowance of 4GB per day and a reduced speed feature; they are not truly unlimited. For true unlimited data, the Truly Unlimited Data for India plans are the relevant options.
