Description
Cambodia's tourist triangle — Siem Reap for Angkor, Phnom Penh for the capital, and the southern coast around Sihanoukville and Kep — is navigable without a local SIM, but barely. Grab and PassApp run every city ride, most guesthouses confirm bookings through Telegram or WhatsApp, and the sunrise-at-Angkor Wat crowd depends on live updates about gate opening times. A Blikst Cambodia eSIM rides on the Viettel network (branded locally as Metfone, the country's largest operator by coverage), with 4G across the main cities and along the national highways and 3G backfill in the rural interior. Install before you fly, land at Phnom Penh (PNH) or Siem Reap–Angkor International (SAI), and skip the roadside SIM stall.
Where Metfone/Viettel covers
Phnom Penh, Siem Reap, Battambang, Sihanoukville, and Kampot all get consistent 4G. National Road 6 (Phnom Penh to Siem Reap) and National Road 4 (Phnom Penh to Sihanoukville) are well covered. The Angkor Archaeological Park perimeter has 4G at the main temples — Angkor Wat, Bayon, Ta Prohm — and 3G at outlying sites like Banteay Srei. The Cardamom Mountains and the northeastern provinces of Ratanakiri and Mondulkiri drop to 3G or edge near villages and are often offline between them. Koh Rong and Koh Rong Samloem have limited signal on the east sides and very little on the west.
Cost vs. buying a SIM at the airport
Metfone, Smart, and Cellcard all sell tourist SIMs at PNH and SAI arrivals for around $5–$10 with a few GB of data and passport registration on the spot. It works — but the queue after a late-night AirAsia or Singapore Airlines arrival is long, and many travellers end up overpaying at Siem Reap's unregulated sidewalk stalls. A Blikst eSIM skips both. Against US or EU roaming at $10–$12 per day, a 15-day 5 GB plan undercuts two days of home-carrier charges.
Arrival and the tuk-tuk
Install the profile at home over Wi-Fi. Phnom Penh International has free airport Wi-Fi; Siem Reap's new SAI airport (opened 2023, 40 km from the city) also does. Once airplane mode is off, the Blikst line registers on Metfone automatically. Open PassApp or Grab, book a tuk-tuk or car, and you're on your way. The new SAI airport has introduced a fixed-price shuttle into Siem Reap town — booking needs data.
Apps that run Cambodia
- PassApp and Grab: PassApp is Cambodia-native and has deeper tuk-tuk and moto coverage in smaller cities. Grab dominates Phnom Penh for cars. Both are far cheaper than negotiating at a hotel taxi rank.
- Telegram: Many hotels, tour guides, and boat operators prefer Telegram over WhatsApp in Cambodia. Download it before you land if you don't use it at home.
- ABA Mobile and Wing: Local banking and payment apps. Tourists rarely register but the KHQR payment standard (scan a QR to pay) is everywhere — some foreign cards support KHQR through partner apps now.
- Offline Angkor maps: The Angkor Enterprise official app and Maps.me both work well for the park. Signal dips at the outer temples, so downloading ahead is worth the five minutes.
Plan sizing
A three-day Siem Reap temple run with guesthouse Wi-Fi works on 1–3 GB. A one-week Phnom Penh–Siem Reap–coast loop fits 5 GB. Two-week itineraries that include Mondulkiri, Battambang's bamboo train, and island time on Koh Rong need 10 GB to cover the rural legs comfortably. Digital nomads based in Phnom Penh or Siem Reap for a month should pick 20 GB or more — 4G is generally strong, and it's easy to rely on mobile data over patchy guesthouse Wi-Fi.
Install the eSIM before boarding. Land at PNH or SAI with data live, and the first tuk-tuk booking goes through before you've cleared the taxi touts. One QR code, a Metfone line, and a working connection from arrivals to Angkor sunrise.

I used to have 3 mobile but the internet connection was not the best, that’s why I started to use Blikst and I find it very useful
eSIM FAQ
The Blikst Cambodia eSIM rides on the Viettel network, branded locally as Metfone, which is the country's largest operator by coverage. You get 4G across the main cities and along the national highways, with 3G backfill in the rural interior. That gives you a fast, reliable connection where most travellers spend their time, and a usable fallback when you head off the beaten track.
Phnom Penh, Siem Reap, Battambang, Sihanoukville and Kampot all get consistent 4G, and National Road 6 and National Road 4 are well covered. Angkor's main temples — Angkor Wat, Bayon, Ta Prohm — have 4G, with 3G at outlying sites like Banteay Srei. Be realistic about the Cardamom Mountains, Ratanakiri and Mondulkiri, which drop to 3G or edge and are often offline between villages. Koh Rong and Koh Rong Samloem have limited signal, mostly on the east sides.
Right after purchase you receive a confirmation email with your eSIM details, then you scan the QR code provided to install the profile. Do this at home over Wi-Fi before you fly. Activation is automatic: the eSIM activates on arrival in Cambodia, so once you land at Phnom Penh (PNH) or Siem Reap–Angkor (SAI) and switch off airplane mode, the Blikst line registers on Metfone by itself. No roadside SIM stall needed.
Most modern smartphones are fully compatible with Blikst eSIMs, though a few exceptions exist, so check our detailed compatibility list to confirm your device. As a quick check, on iPhone look under Settings > General > About for an EID number, and on Android check your network or SIM settings for eSIM support. Your phone also needs to be carrier-unlocked. If you see an EID and your handset is unlocked, you are almost certainly good to go.
It depends on your trip. A three-day Siem Reap temple run with guesthouse Wi-Fi works on 1 to 3 GB. A one-week Phnom Penh, Siem Reap and coast loop fits around 5 GB. Two-week itineraries taking in Mondulkiri, Battambang's bamboo train and Koh Rong need about 10 GB to cover the rural legs comfortably. Digital nomads settling in for a month should pick 20 GB or more, since 4G is strong and easy to lean on over patchy guesthouse Wi-Fi.
Yes, tethering and hotspot are supported, so you can share your connection with a laptop, tablet or a travelling companion's phone. That is handy for working from a Phnom Penh cafe or keeping a group online during an Angkor day trip. Just remember that hotspot use draws from the same data allowance as your phone, so size your plan accordingly if you expect to tether often during your stay.
This is a data plan, so it does not come with a local Cambodian phone number for traditional calls or SMS. In practice that is rarely a problem: you make calls and send messages over the internet using apps like WhatsApp, Telegram or FaceTime — and Telegram in particular is widely used by Cambodian hotels and guides. Because the eSIM is a separate digital line, you can leave your physical home SIM in the phone to keep your usual number active.
Usually, yes. Metfone, Smart and Cellcard sell tourist SIMs at PNH and SAI arrivals for around $5 to $10 with a few GB and passport registration, but the queue after a late-night arrival is long and many travellers overpay at Siem Reap's unregulated sidewalk stalls. Against US or EU roaming at roughly $10 to $12 a day, a 15-day 5 GB Blikst plan undercuts just two days of home-carrier charges, and you skip the airport queue entirely.
