RedSim does not provide a truly unlimited high‑speed data eSIM for El Salvador. All of its plans that carry “Unlimited” in the name are fixed data plans that give up to 3GB of high‑speed data each day. After the 3GB daily threshold is reached the speed drops to 1000 kbps for the remainder of the day. Examples of these fixed data plans are the El Salvador Unlimited 3‑Day, 5‑Day, 7‑Day, 10‑Day, 15‑Day and 30‑Day options, each listed with a 3GB/day data cap and a reduced speed after that limit. These fixed‑data plans can be more cost‑effective unless the traveler expects to consume far more data than the allotted amount.
