AeroSims eSIM Data Plans for Serbia

AeroSims does not provide a truly unlimited data eSIM for Serbia. The plans listed as “Serbia Unlimited” give 3GB of high‑speed data per day; after the 3GB limit is reached the speed is reduced to 1000kbps.

Travelers looking for larger data allowances can choose fixed‑data plans instead. Examples are a 20GB plan valid for 30 days and a 50GB plan valid for 180 days, both of which offer the full data at the standard speed for the entire validity period. These alternatives are often more cost‑effective for those who need more than 3GB per day but do not require unlimited data.

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 and 20 multi‑country data plans that cover Serbia. The plans vary from $4.90 to $117.43 and offer data caps between 3 GB and 50 GB, with validity periods ranging from one day to 180 days. Some plans feature daily data caps while others have fixed data amounts, and a few include a reduced speed option of 1000 kbps.
