Manet Travel does not provide an unlimited‑data eSIM for Cambodia. The plans it lists for Cambodia are fixed data bundles with set amounts and a 30‑day validity, such as 50 GB, 20 GB, 10 GB, 5 GB and 3 GB. These bundles can be a cost‑effective choice for most travelers, especially if their data usage is moderate. For heavy users who need more data, choosing a larger fixed bundle such as the 50 GB plan could be more economical than repeating smaller purchases.
