EtravelSIM eSIM Data Plans for Serbia

EtravelSIM does not provide a true unlimited high‑speed data eSIM for Serbia. All plans listed for Serbia either allow a fixed amount of high‑speed data, such as 50 GB or 25 GB for 30 days, or they are named “Unlimited” but actually provide only 4 GB per day of high‑speed data, after which the speed drops to 128 kbps.

If you need a large data allowance without the throttling, a fixed‑data plan like the 50 GB 30‑day option at $29.19 USD or the 25 GB 30‑day option at $21.99 USD would be more cost‑effective than the 4 GB/day “Unlimited” plans for typical travel use.

EtravelSIM does not provide a Serbia eSIM with a phone number or SMS capability. Only data‑only eSIM plans are sold for Serbia. Travelers can still use popular VoIP services such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging.

EtravelSIM currently offers 6 single country data plans and 43 multi country data plans that cover Serbia. The catalogue includes both fixed data cap plans, where a set amount of data is allocated for the entire validity period, and daily data cap plans, which limit the amount of data that can be consumed each day. Prices range from about $4.50 to $109.99, and the data caps offered span from 1 GB up to 50 GB, with validity periods varying between 5 and 365 days.
