4S eSIM does not offer a truly unlimited data eSIM for Europe. All of the plans that carry “Unlimited” in their name have a fixed data allowance—such as “Europe+ 3GB Unlimited – 1 days, ” which is capped at 3 GB and throttles to 1000 kbps once the limit is reached. If a traveler needs higher capacity, 4S eSIM provides fixed‑data options instead. For example, the “Europe+ 50GB – 5 days” plan delivers 50 GB of high‑speed data for five days, while the “Europe+ 20GB Unlimited – 7 days” offers a 20 GB allowance at the same 1000 kbps‑reduced speed after the threshold. Choosing a fixed data plan can be more cost‑effective unless the user requires continuous, unlimited high‑speed connectivity.
4S eSIM does not provide a Europe eSIM plan that includes a phone number or SMS capability. The provider offers only data‑only eSIMs for European travelers. If calls or messages are required, users can rely on internet‑based VoIP services such as WhatsApp, Telegram, or iMessage, which work over the data connection and do not need a traditional phone number or SMS.
