NiftySIM does not provide an unlimited data eSIM for East Asia. All of its plans for the region have a fixed data cap, such as the Asia 50GB 180 days plan and the Asia 20GB 30 days plan, which offer 50 GB and 20 GB of high‑speed data respectively.
Because the data allowance is capped, a fixed data plan can be more cost‑effective for most travelers, unless the user expects to consume data well beyond the plan’s limit.
