No, Flysimio does not provide a truly unlimited data eSIM plan for Guatemala. The plan titled “Guatemala Unlimited” delivers only 2GB of high‑speed data per day for a 7‑day period and is not a hard‑limit free‑usage plan. Travelers who require larger amounts of data can opt for fixed‑data plans such as the “Guatemala 20GB 30Days” plan, which offers 20GB for 30 days, or the “Guatemala 10GB 30Days” plan, which provides 10GB for 30 days. Choosing a fixed data plan can be more cost effective unless the user is an extremely heavy data consumer.
