abesteSIM does offer unlimited‑data eSIM plans for Estonia. The company provides a range of validity options from 1 day up to 30 days, with prices that span from $1.91 for the 1‑day plan to $192.63 for the 30‑day plan. Each unlimited plan includes tethering and the possibility of speed throttling.
Unlimited data means there is no hard data cap, though network speeds may be reduced after heavy usage as part of a fair‑use policy. Travelers who are concerned about potential speed restrictions should contact abesteSIM to confirm the typical amount of data that remains available at normal speed.
