Voye Global does not provide a truly unlimited data eSIM for Portugal. Plans that include “Unlimited” in their name, such as the Portugal 3‑Day, 7‑Day, 10‑Day, 15‑Day, 20‑Day, and 30‑Day options, actually give a fixed high‑speed data allowance of 2GB per day; after that amount is reached the speed may be throttled, but the exact reduced speed is not specified in the data.
Instead, travelers can choose one of the fixed‑data plans that Voye Global offers. For example, a 30‑day plan provides 25GB of high‑speed data for Portugal, and a 365‑day plan delivers 50GB of data for the entire year. These alternatives offer larger data allowances and may be more cost‑effective for users who need a substantial amount of high‑speed data while traveling in Portugal.
