Does 4S eSIM offer unlimited data eSIM for Balkans?
4S eSIM does not provide a truly unlimited data eSIM for the Balkans. All plans the provider lists have a fixed data allowance, even those marked “Unlimited” in the name; after reaching the cap, the speed is throttled to 1000 kbps. For travelers who want a large quantity of high‑speed data, 4S eSIM offers fixed‑data plans such as 50 GB for 5 days or 20 GB for 15 days, which can be more cost‑effective unless one expects to use far more data than the allowance.
Does 4S eSIM offer Balkans eSIM with phone number and SMS?
4S eSIM does not offer an eSIM plan with a phone number or SMS capability for the Balkans. Only data‑only plans are available for this region.
Travelers who need to make calls or send messages can use popular VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations in the Balkans may block or restrict access to certain apps or VoIP services, so it is advisable to verify that the applications you rely on are accessible before purchasing.
What countries are covered by 4S eSIM's eSIM plans in Balkans?
The 4S eSIM Balkans+ plan covers Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Montenegro, North Macedonia, and Serbia. The Global plan includes the same Balkan countries plus coverage in many other regions worldwide.
