4S eSIM does not provide a truly unlimited high‑speed data eSIM for Europe. Plans that carry “Unlimited” in the name, such as Europe+ 3GB Unlimited or Europe+ 5GB Unlimited, still have a fixed data cap and the speed is throttled to 1000kbps after that limit is reached. Travelers who need more data can opt for one of the fixed‑data plans offered by 4S eSIM, such as the Europe+ 50GB plan valid for 30 days or the Europe+ 30GB plan valid for 15 days, which provide larger data allowances without the post‑cap speed reduction. Selecting a fixed data plan is often more cost‑effective for users who consume a substantial amount of data while traveling in Europe.
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.
The 4S eSIM Europe+ plan lists the following countries in Europe: Austria, Belgium, Bulgaria, Switzerland, Cyprus, Czech Republic, Germany, Denmark, Estonia, Spain, Finland, Faroe Islands, France, United Kingdom, Gibraltar, Greece, Croatia, Hungary, Ireland, Iceland, Italy, Liechtenstein, Lithuania, Luxembourg, Latvia, Malta, Netherlands, Norway, Poland, Portugal, Romania, Sweden, Slovenia, Slovakia, and Ukraine. The 4S eSIM Global plan covers the same set of European countries and additionally includes Albania, Bosnia and Herzegovina, Montenegro, North Macedonia, Serbia, and Russia. These plans do not cover regions outside Europe that are listed in the “Other Regions covered” column.
