No, nextSIM does not offer a truly unlimited high‑speed data eSIM for Malawi. Plans called “Unlimited” give only 1GB or 2GB of high‑speed data per day, after which the speed is throttled to 512 kbps or 2000 kbps, so the data is capped.
Instead, nextSIM provides fixed data plans that may be more cost effective for most travelers. For example, the eSIM Malawi 10GB 30Days Premium supplies 10GB of high‑speed data for 30 days, and the eSIM GLOBAL 30GB 30Days Premium offers 30GB of high‑speed data that covers Malawi and 157 other countries. These fixed‑data options give unlimited high‑speed access within the allotted amount and may suit those who need steady connectivity.
