No, shibaSIM does not provide a truly unlimited data eSIM for travelers in Norway. All of their plans listed for Norway have a hard cap on high‑speed data, typically expressed as a daily allowance (for example, 3 GB/day), and the speed drops to 128 kbps after the cap is reached.
Travelers who need more data can choose one of the fixed‑data plans that offer larger daily allowances. An example is the Europe (44 countries) Unlimited plan that gives 3 GB/day of high‑speed data for 20 days at $31.09 USD. Other high‑cap options include 2 GB/day for 30 days or 30 GB for 30 days, which may better suit heavier data users.
