merdata does not offer an unlimited data eSIM for the Dominican Republic. All available plans have a hard data cap, such as 20 GB, 10 GB, or 5 GB, each with a fixed validity period of 30 days (or 1 day for reduced‑speed options).
Travelers can choose a fixed data plan that fits their usage needs; for example, the 20 GB plan costs $53.54 USD and is valid for 30 days, while the 10 GB plan costs $32.08 USD for the same duration. These options provide a clear data allowance and a defined period of use, which can be more cost‑effective than purchasing a pay‑as‑you‑go credit for heavy data consumption.
