nextSIM does not provide a service with an unrestricted high‑speed data allowance for the Dominican Republic. All plans in the catalog have a defined data cap, with the highest being 2GB per day or a 50GB bundle that lasts 30–180 days. The plans that carry “Unlimited” in their names are fixed data plans that offer a set amount of high‑speed data and then throttle speed to 512 kbps or 2000 kbps once the limit is reached.
For travelers who need a larger amount of data, nextSIM offers fixed data alternatives such as the Pro 50GB plans, which provide 50GB of high‑speed 5G data for 30, 60, 90, 120 or 180 days. These options can be more cost‑effective unless the user is an extremely heavy data consumer.
