4S eSIM sells several eSIM packages for Romania that carry the word “Unlimited” in their names, but each of these plans actually contains a fixed high‑speed data allowance. For example, the Romania 50GB Unlimited – 5 days plan gives 50GB of high‑speed data for $20.01 USD before the speed drops to 1000 kbps. Across the catalog every “Unlimited” package has a similar behaviour, applying a reduced speed after the specified data cap is reached.
If a traveler prefers a truly unlimited experience, 4S eSIM does not provide such a plan for Romania. Instead, customers can choose from several fixed‑data options, such as the 50GB – 5 days plan or the 20GB – 5 days plan, which offer large amounts of high‑speed data without the speed throttling that applies to the “Unlimited” packages.
4S eSIM does not provide an eSIM plan for Romania that includes a local phone number or SMS service. All plans sold by this provider are data‑only, so travelers who need voice or text functionality will have to rely on internet‑based options. VoIP and messaging apps such as WhatsApp, Telegram, or iMessage can generally be used over the data connection, but the availability of these services can vary, and travelers should confirm that the apps they rely on are accessible in Romania before purchasing a plan.
4S eSIM offers a total of 54 single‑country data plans and 108 multi‑country data plans for travelers in Romania. The available plans vary widely in price – from roughly $1.42 to $195.83 – and in data size, ranging from 714 MB up to 50 GB with validity periods that span from one day to a full year. Among these offerings, plans are split into fixed‑data‑cap options, providing a set amount of data for the duration of the plan, and daily‑data‑cap options, which allocate a specific amount of data to be used each day. This combination allows travelers to choose the plan that best matches their usage patterns and budget.
