eSIMatrix does not provide an unlimited data eSIM for Estonia. The plans it offers for the country are fixed‑data options, such as the Estonia 20GB pack valid for 30 days priced at $21.50 USD and the Europe 20GB pack covering Estonia valid for 30 days priced at $24.00 USD. Both plans provide 20GB of high‑speed data for the specified duration.
Because unlimited data plans are absent, travelers who need more than a few dozen gigabytes may find a fixed plan cheaper, especially if their usage stays within the data allowance. If very heavy data consumption is expected, they may have to consider other providers that offer unlimited options.
