No, nextSIM does not provide truly unlimited high‑speed data plans for Cambodia. Plans that include “Unlimited” in their name actually have a fixed data cap, after which the connection speed is throttled; for example, eSIM Unlimited Standard 1 Day Cambodia offers 1GB of data before the speed is reduced to 512kbps, and eSIM Unlimited Plus 1 Day Cambodia gives 2GB before the speed drops to 2000kbps.
Travelers who need more data can select fixed‑data options. A 10GB 30 days Cambodia plan supplies 10GB of high‑speed data for 30 days, and the eSIM GLOBAL 30GB 30Days Premium provides 30GB for the same period. Fixed plans can be more cost‑effective for users who consume large amounts of data.
