ZapSim does not provide a truly unlimited data eSIM for Brazil. Every plan listed in the provider’s catalogue has a hard data cap; the term “Unlimited” in the plan names refers to a fixed daily allowance, after which the connection speed is throttled to a lower bandwidth. For example, plans such as “Brazil Unlimited 1GB/Day 500Kbps 3Days” give 1 GB of high‑speed data each day for three days and then reduce the speed to 500 kbps, while “South America Unlimited 5GB/Day 384Kbps 3Days” offers 5 GB per day for three days with a reduced speed after the limit.
If a traveler needs a large amount of data without daily limitations, ZapSim offers fixed data bundles such as the “Brazil 50GB 30Days” plan, the “South America (6 areas) 30GB 30Days” plan, and the “Brazil 20GB 30Days” plan, all of which provide high‑speed data for a 30‑day period. These fixed data plans can be more cost‑effective for users who anticipate substantial data usage throughout their stay in Brazil.
