eSIMCard does not provide a genuinely unlimited high‑speed data plan for Estonia. All plans that carry the words “Unlimited” in their names actually contain a fixed data allowance, such as 1GB per day or 2GB per day, after which the speed is throttled to a reduced rate (for example 512 kbps or 2000 kbps). Because of this limitation, users who need continuous high‑speed data would need to choose one of the fixed‑data options.
If a large data allowance is preferable, eSIMCard offers fixed‑data plans such as 50 GB for 30 days or 35 GB for 30 days. These plans give high‑speed data throughout the validity period and can be more cost‑effective for travelers who consume more data than the capped “Unlimited” packages allow.
