AeroSims eSIM Data Plans for Serbia

AeroSims does not provide a truly unlimited high‑speed data plan for Serbia. The plans that carry the name “Serbia Unlimited” actually give a cap of 3 GB per day, and once this limit is reached the speed is reduced (the specific reduced speed is not listed). For travelers who need a larger data allowance without the need for a daily limit, AeroSims offers fixed plans such as Serbia 20 GB / 30 days and the Europe (40+ Countries) 50 GB / 180 days plan that includes Serbia coverage. These fixed‑data options can be more cost‑effective for users who expect to consume a substantial amount of data during their stay.

AeroSims does not provide an eSIM for Serbia that includes a phone number or SMS capability. The provider offers only data‑only eSIMs for the country. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but some services may be restricted or blocked in Serbia, so it is advisable to verify that the apps needed are accessible before purchasing an eSIM.

AeroSims provides 11 single‑country data plans that cover only Serbia and 20 multi‑country plans that include Serbia as part of a broader coverage. The single‑country options range in price from roughly $4.90 to $35, and the data cap ranges from 3 GB to about 20 GB with validity periods from 1 to 30 days. The multi‑country plans span a price range of approximately $25 to $117.43, offer data caps between 5 GB and 50 GB, and have validity from 30 to 180 days. Providers normally offer two main types of plans: fixed‑data‑cap plans give you a set amount of data for the entire validity period, while daily‑data‑cap plans reset the data allowance each day, allowing for a more flexible usage pattern.
