nextSIM eSIM Data Plans for Cambodia

nextSIM does not offer a plan with truly unlimited high‑speed data. Every plan that uses the word “Unlimited” has a fixed data cap, and once that cap is reached the speed is reduced. For instance, the eSIM Cambodia Unlimited 1Days Standard gives 1 GB for 1 day and then lowers speed to 512 kbps, while the eSIM Cambodia Unlimited Plus 7Days Standard provides 2 GB per day for 7 days before throttling to 2000 kbps.

If a traveler wants a larger, unthrottled data allowance for a set period, nextSIM’s fixed‑data plans are an alternative. Examples include the eSIM Pro Cambodia 20GB 30Days Mobile Data + SMS Number, which delivers 20 GB for 30 days, and the eSIM GLOBAL 50GB 30Days Premium, which offers 50 GB for 30 days. Both options give a fixed, high‑speed data amount that does not include a throttle after a set limit.

There are no nextSIM plans that provide a phone number or SMS service for Cambodia. Travelers can only purchase data‑only eSIMs from nextSIM for this destination. They can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging, although some destinations may block or restrict access to certain apps, so users should verify that the services they rely on are usable in Cambodia before buying.

nextSIM lists 39 single‑country data plans that cover Cambodia. There are no separate multi‑country plans that include Cambodia as their sole destination.

The available plans span a price range from about $14.53 to $1, 278.53 and a data cap ranging from 1 GB up to 50 GB. Some plans are priced with a fixed data quantity, while others offer a daily data cap that limits usage each day. The daily caps vary, with 6 plans featuring this option, giving travelers flexibility in how much data they consume on a day‑by‑day basis.
