ByteSIM does not provide a truly unlimited data eSIM for Andorra. The plans that carry an “Unlimited” name actually offer a capped 1 GB per day of high‑speed data; once that amount is reached the speed drops to 10240 kbps. If a traveler is willing to accept a speed reduction after a fixed quota, these options can work, but they are not unlimited data. For users who prefer a larger, fixed allocation without the daily cap, ByteSIM offers alternatives such as a 50 GB plan valid for 28 days at $68.90 USD or a 30 GB plan valid for 10 days at $59.90 USD. These fixed‑data plans may be more cost‑effective for heavy data users compared to the capped “Unlimited” options.
