Qrispy eSIM does not provide any unlimited data eSIM plans for Brunei. All of the available options in the Brunei catalog are pay‑as‑you‑go data credits, with the amounts listed in the Data cap column indicating roughly how much data the purchased credit is worth at the local rate. For example, the largest current offering is the Brunei 10GB plan, which roughly provides 10 GB of data that can be used at any time; unused credit does not expire and can be topped up again if more data is needed. Small‑scale plans such as the 5GB, 3GB, 2GB and 1GB credits can also be purchased. Because the credit is only tied to actual usage, travelers can add more data as required, making the pay‑as‑you‑go model a flexible choice for those who want to avoid a fixed data allowance.
