eSIM for Koh Rong
Koh Rong is Cambodia's most popular island, a stretch of white-sand beaches, turquoise water and jungle interior reached by ferry from Sihanoukville. It runs from the lively backpacker hub of Koh Touch to quieter beaches like Long Set and Sok San. It is a place to switch off, and connectivity reflects that: signal is usable around the main village but drops away on the remoter beaches and across the island, so plan to be partly offline.
An eSIM Cambodia gives you access to the same plans in Koh Rong as in the rest of the country. 5 GB is generally enough for maps, messaging and social media, while video streaming and hotspot use require more data. The plans shown range from 1 to 20 GB and start at $1.90. They are fully refundable within 30 days provided the eSIM has not been used on a network at the destination. The activation link is sent by email after purchase.
Getting connected in Koh Rong
Koh Rong is reached by a 30 to 45 minute ferry from Sihanoukville, with signal dropping on the crossing and returning patchily near the island. The crucial preparation is to download maps, music and anything you need before boarding, since the island's coverage is limited and concentrated around the main village. With an eSIM active you will have usable signal at Koh Touch on arrival, but the remoter beaches where many stay have thin or no coverage, so save your accommodation contact before crossing.

Coverage in Koh Rong
Koh Rong's coverage centres on the main village. Koh Touch, the busy ferry-arrival hub with hostels, bars and restaurants, has usable but patchy 4G on Smart and Cellcard, which can slow when the village is busy. Metfone is the steadier pick across the wider island. Coverage drops away from the village: the popular beaches like Long Set (4K Beach), Sok San and the quieter northern bays have thin or no signal, and the jungle interior between them is largely offline. Some resorts run their own wifi, sometimes by satellite, but mobile coverage on the remoter sands is minimal. This is an island to treat as partly disconnected, where the village is your connectivity base.
Best network here
Metfone for the steadiest island reach; Smart in the village
| Area | Best network | What to expect |
|---|---|---|
| Koh Touch village | Smart / Cellcard / Metfone | Usable but patchy 4G at the ferry hub; slows when busy. |
| Long Set (4K) Beach | Metfone | Thin signal on the popular beach; Metfone holds best. |
| Sok San Beach | Metfone | Patchy on the long western beach; largely reliant on resort wifi. |
| Jungle interior | none | Largely offline between the beaches; download maps first. |
| Ferry crossing | none | Signal drops on the crossing; returns patchily near the island. |
Where to stay and connect in Koh Rong
Koh Touch
The lively backpacker village at the ferry pier with hostels and nightlife. Usable but patchy coverage, the island's main connectivity point.
Long Set (4K) Beach
A long white-sand beach a walk from the village, calmer with bungalows. Thin signal; lean on resort wifi.
Sok San
The long western beach with resorts and a fishing village. Patchy mobile signal; some resorts have satellite wifi.
Northern bays
The quietest, remotest beaches and eco-stays. Largely offline; treat as a true disconnect.
Staying online while you move
Getting around Koh Rong is on foot, by boat taxi between the beaches, or the rough jungle trails, with no roads or ride apps. Coverage holds usably around Koh Touch but drops on the boat taxis and trails to the other beaches, so download offline maps before exploring. The ferry from Sihanoukville loses signal on the crossing. For the remoter beaches and any boat or trail trip, save your accommodation and boat-taxi contacts in advance, since you will be largely offline between the village and the bays.
How much data in Koh Rong
Coverage, not volume, is the constraint on Koh Rong. A stay might use only 2 to 4 GB because the remoter beaches are largely offline and even the village data is patchy. There is little point in a large plan for the island. The priority is downloading maps, music, shows and anything you need before the ferry, saving accommodation contacts, and accepting that Koh Rong is a place to disconnect. Resort wifi, where it exists, can be slow or satellite-based, so handle anything important from the village or before crossing.
Apps worth having in Koh Rong
| App | Why it helps here |
|---|---|
| Google Maps offline | Essential. Download Koh Rong and the beaches before the ferry, since the island beyond the village is largely offline. |
| Telegram | Widely used in Cambodia; save your accommodation and boat-taxi contacts before crossing to confirm arrangements. |
| Downloaded entertainment | Download music, podcasts and shows before the ferry, as streaming is unreliable on the remoter beaches. |
| Windy | Check sea conditions before the ferry crossing and any island boat trips, especially in the rainy season. |
| ABA Mobile / cash | Carry US dollar cash, essential on the island, as card and app payments are unreliable on the patchy signal. |
