4S eSIM does not provide a truly unlimited data eSIM for the Baltic countries. All plans that include “Unlimited” in the name actually offer a fixed data allowance that is reduced to 1000kbps after the specified amount is used. For example, the “Europe+ 50GB – 5 Days” plan gives 50GB of high‑speed data for five days before the speed drops, and the “Europe+ 50GB – 90 Days” plan offers the same 50GB data for 90 days with the same throttling after the limit is reached.
If you need a larger data allowance, 4S eSIM sells fixed data plans that are likely more cost‑effective for heavy users. Examples include the 50GB fixed bundle for 5, 7, 15, 30 or 90 days and the 20GB bundle for five or seven days. These plans give a known high‑speed data amount with a clear validity period, while unlimited‑named plans still have a hard cap and speed reduction.
4S eSIM does not provide a Baltic eSIM plan that includes a phone number or the ability to send and receive SMS. The available Baltic plans from this provider are data‑only.
If you need voice or messaging capabilities while traveling in Baltic, you can typically rely on VoIP applications such as WhatsApp, Telegram, or iMessage that use the data connection. Travelers should verify that these services are accessible in the specific Baltic country, as some destinations may block or restrict certain apps or VoIP services.
Both the Europe+ and Global plans offered by 4S eSIM include coverage for Estonia, Lithuania and Latvia; each of these plans also extends service to other regions beyond the Baltic but those territories are not listed here.
