4S eSIM does not provide a true unlimited data eSIM for Uganda; all plans list a specific data cap. Plans that include “Unlimited” in the name still limit high‑speed usage to a set amount—after the allotted GB the speed drops to 1000 kbps, as indicated in the plan details. Travelers who need a higher overall data allowance may choose a fixed‑data plan, such as the 50GB for 30 days or the 20GB for 15 days, which provide large data pools without a speed reduction after a cap is hit. These fixed plans can be more cost effective for most users, while very heavy data consumers may prefer a higher‑cap plan or a combination of shorter‑validity plans.
4S eSIM does not provide a prepaid eSIM for Uganda that includes a local phone number or SMS capability. Travelers can only obtain a data‑only eSIM from this provider, and communication such as calls and messages can be handled through internet‑based applications like WhatsApp, Telegram, or iMessage.
4S eSIM offers 48 single‑country data plans for Uganda, with no multi‑country options available. The plans are priced between $5.21 and $235.43, covering data caps from 714 MB up to 50 GB and validity periods ranging from one to 365 days. Among these plans, 9 are structured with a daily data cap while 39 are fixed data cap offerings, giving travelers a choice between a consistent daily allowance or a larger, one‑time data bundle.
