No, yaySIM does not provide an unlimited data eSIM for the Netherlands. All plans for the destination have a defined data cap and a set validity period.
Travelers who need a high‑volume data allowance can select from fixed‑data options such as the EU‑35_100_180 plan, which offers 100GB valid for 180 days, or the NL_50_30 plan, which gives 50GB for 30 days. Choosing one of these fixed‑data plans may be a more cost‑effective choice for heavy data users compared to purchasing Pay‑as‑you‑go credit.
