4S eSIM does not provide a truly unlimited data eSIM for Europe. Plans that carry “Unlimited” in the name actually have a fixed data allowance and, once that amount is used, the speed is reduced to 1000kbps.
Travelers who need a large amount of high‑speed data can choose from 4S eSIM’s fixed data plans. For example, the Europe+ 50GB plan is available for 90 days at $26.78 USD, and the Europe+ 50GB plan for 30 days costs $24.61 USD. These plans give 50GB of high‑speed data for the specified validity period and are more cost‑effective for most users unless they require an extremely heavy data consumption that would exceed the fixed allowance.
4S eSIM does not provide a Europe eSIM with a phone number or SMS capability. The provider only offers data‑only plans for Europe. Travelers can use popular VoIP applications such as WhatsApp, Telegram and iMessage over the data connection for voice and text communications; however, some destinations may block or restrict these services, so users should verify that the apps they rely on are accessible before purchasing.
