Cheapest unlimited eSIM for Cambodia? From €7.95 for 3 days (October 2026)

The Roam2Go unlimited eSIM for Cambodia starts from €5.95 for 1 day, with no roaming surprises and instant activation directly on your phone. Whether you’re heading to Angkor Wat, Phnom Penh or the southern beaches, having data from the moment you arrive makes the difference between a smooth trip and a frustrating one. Below you’ll find all available plans, tips for choosing the right one and everything you need to know before you go.

Unlimited plans for Cambodia: 3, 5 and 7 days (and more)

Roam2Go’s unlimited plans for Cambodia are designed for short and medium-length trips. They work with a daily high-speed data allowance; once it’s used up, speeds are reduced until the allowance resets the following day, but your connection is never interrupted. For typical travel use — maps, messaging, social media and the occasional video call — this is more than enough.

Here are the available unlimited durations and their exact prices:

• 3-day unlimited: €7.95
• 5-day unlimited: €11.95
• 7-day unlimited: €16.95
• 10-day unlimited: €27.95
• 15-day unlimited: €34.95
• 30-day unlimited: €59.95

If your trip lasts exactly a week, the 7-day plan at €16.95 is the natural choice. For long weekends or short visits of 3 to 5 days, the shorter plans offer great value for money. And if you’re planning a month exploring the country in depth, the 30-day plan takes away any worry.

Which plan to choose based on your trip

Short break (up to 5 days)

If you’re travelling for a few days to visit Angkor Wat or explore Phnom Penh, the 3-day unlimited plan (€7.95) or the 5-day plan (€11.95) will comfortably cover your everyday needs: maps, Google Translate, booking tuk-tuks or sharing photos. If your usage is very light and you’re not planning any streaming, a fixed-data plan of 1 or 2 GB may be enough and will work out even more affordable.

One-week trip or classic circuit

The most popular Cambodia itinerary — Siem Reap, Phnom Penh and perhaps the beaches of Sihanoukville — usually lasts between 7 and 10 days. In this case, the 7-day unlimited plan at €16.95 is a very solid choice: you don’t need to monitor your usage and can use your phone with complete freedom. If your trip runs a few days longer, the 10-day plan at €27.95 gives you a bit of extra breathing room.

Long stays or digital nomads

For stays of a month or if you’re working remotely during your trip, the 30-day unlimited plan (€59.95) is the hassle-free solution. Alternatively, the 10 GB or 20 GB fixed-data plans can be a good option if you have Wi-Fi at your accommodation and only use mobile data for occasional tasks.

Why an eSIM rather than a local SIM?

Buying a local SIM at Phnom Penh or Siem Reap airport is possible, but it means queuing, assistance isn’t always available in English, and you’ll need to swap the physical card in your phone — something many travellers would rather avoid. With a Roam2Go eSIM, the process is completely different:

• Buy online from home, even on the last day before you leave.
• Receive your QR code by email and scan it in under two minutes.
• Arrive in Cambodia with data ready to go, no waiting, no queuing.
• The price is fixed in euros, with no roaming charges or surprise bills.
• Your regular SIM stays free to receive calls or texts from your home country, with its data roaming switched off. As Cambodia is outside the EU, your provider’s voice and SMS roaming is normally switched off by default (if you want it, you have to ask for it) and, if it’s on, you may be charged for calls you make and receive and for texts.

Other eSIM providers offer similar services, but it’s worth comparing the terms carefully: some charge activation fees or don’t clearly explain the fair-use policy on unlimited plans. At Roam2Go, what you see on the product page is what you pay.
