Remote Work from Phnom Penh: Internet, Power and Coworking

Prepared by the NovAsia Editorial Team

Phnom Penh can work well as a base for remote work, provided that you build redundancy into the setup from the start: home fibre internet, a mobile SIM from a different operator, backup power for the router and somewhere else you can work for a day if the apartment becomes unusable. The city has enough infrastructure for video calls, cloud services, software development, design, online teaching and remote management. Reliability, however, depends less on an advertised headline speed than on the exact building, line and neighbourhood.

The most common mistake is to choose an attractive apartment, run one speed test in the afternoon and assume the issue is settled. A proper test happens in the evening, during a real video call and while switching to mobile data. A remote worker does not need the fastest package in Phnom Penh. They need a system that continues to function after a fibre cut, power outage or heavy storm.

What Phnom Penh offers remote professionals

The main advantage is the combination of modern housing, inexpensive mobile data, multiple fibre providers and a growing range of places to work outside the home. A private office or a car is not required to get started.

The Telecommunication Regulator of Cambodia reported more than 20.6 million mobile subscriptions nationwide as at April 2025. The number exceeds the population because many users keep more than one SIM card. For remote work, that is a sensible model rather than an oddity: one operator is used every day and another remains active as a backup.

Mobile infrastructure continued to expand in 2026. Smart formally launched 5G in Phnom Penh and Kandal in January 2026 before extending the network further, while Cellcard also offers 4G/5G plans and home-fibre products.

A 5G coverage map does not guarantee a strong signal inside a particular apartment. Concrete walls, coated glass, floor height and the orientation of the building can weaken reception precisely where the desk is located.

Phnom Penh is generally suitable for:

• software development and digital product work;
• design and moderate-volume video editing;
• marketing and project management;
• online consulting;
• sales and client calls;
• e-commerce;
• remote teaching;
• management of an overseas company;
• cloud-based documents and CRM systems.

It is less suitable for work requiring daily transfers of hundreds of gigabytes, consistently low latency to distant overseas servers, local server infrastructure or a guaranteed corporate SLA from a residential apartment.

Home internet: how much speed do you actually need?

A single person working with documents, browsers and video calls will usually be comfortable with a stable symmetrical connection of around 30–50 Mbps. Two remote workers, frequent large uploads or 4K video workflows make 100 Mbps or more more practical.

Do not choose a package by download speed alone. Remote work depends on:

• upload speed;
• latency;
• packet loss;
• evening stability;
• international routing;
• outage recovery time;
• Wi-Fi quality inside the apartment;
• access to Ethernet;
• technical support;
• contract length;
• installation charges;
• early-termination conditions.

SINET publishes residential packages with symmetrical 50 Mbps service and unlimited use, while business packages start at higher speeds. Smart offers home products of up to 250 Mbps, including fibre and 5G Home solutions. Cellcard advertises home fibre speeds of up to 600 Mbps within the local network.

A high local result is not the same as a fast connection to a work server in London, Frankfurt or California. A provider may perform extremely well to a Phnom Penh test node and less impressively to an overseas endpoint.

Ask people in the same building rather than relying on broad neighbourhood recommendations. “SINET works well for me in BKK1” is much less useful than a test from a nearby unit using the same building infrastructure.

The practical conclusion is simple: select the service for the actual workload and address, not the largest number in an advertisement.

How to test internet before signing a lease

A speed test during an apartment viewing is useful but insufficient. It captures one moment and may even be running through the agent’s mobile hotspot rather than the apartment’s home network.

Ideally, arrange a full test day or rent the unit for a few nights. The check should include:

1. Speed tests in the morning, evening and after 8 p.m.
2. Separate download and upload results.
3. A video call lasting at least 30 minutes.
4. A connection through your work VPN.
5. Uploading a large file to the cloud.
6. Testing against an international server.
7. Checking mobile reception in the actual work area.
8. Restarting the router and timing recovery.
9. Testing the Ethernet connection.
10. Asking management about previous outages.

Find out who owns the connection. In some apartments, the landlord pays for a private line. In others, the entire building shares a common service. A shared network may be fine during the day and slow dramatically in the evening.

If internet is included in the rent, ask whether you may install your own line. Saving $20–40 a month is not worthwhile if calls repeatedly fail.

The lease should ideally permit installation of provider equipment and any minimal drilling required for the cable. Otherwise the landlord may refuse a private line after you have moved in.

Mobile internet as a real backup

Mobile data is inexpensive enough in Cambodia to keep a second SIM active permanently. In June 2026, Cellcard advertised 30-day 5G plans including 90 GB for $6, 150 GB for $10 and 250 GB for $15. Smart also offered 5G/4G plans and additional data packages, including 90 GB for $6 in some business products.

Prices and allowances change, so confirm them at the time of purchase. For resilience, a different operator and a strong signal at home matter more than the largest data allowance.

A practical backup system includes:

• a primary fibre provider;
• a backup SIM from operator A;
• another SIM from operator B;
• a phone capable of tethering;
• a mobile router or 5G CPE if needed;
• a power bank;
• saved VPN settings;
• a small prepaid balance.

If the fibre provider and mobile operator belong to the same telecom group or use shared infrastructure, the backup may be less independent than it appears.

Check tethering rules and what happens after the data threshold. “Unlimited” packages sometimes include a fair-use policy or speed reduction.

Mobile internet is excellent for keeping a video call and ordinary work online during an outage. It is less suitable for large cloud synchronisation, rendering and continuous video uploads. Pause background updates and backups when operating on emergency data.

Electricity and backup power

Electricity in Phnom Penh is normally sufficient for home-based work, but planned maintenance and unplanned outages still occur. Electricité du Cambodge continues to publish notices of temporary supply interruptions by area, including during June 2026.

The useful question is not whether “power in Phnom Penh is reliable”. It is what the specific building does when the grid fails.

Ask management:

• whether the building has a generator;
• what the generator powers;
• whether lifts continue to operate;
• whether electricity reaches the apartment;
• whether air conditioners can run;
• whether shared network equipment remains powered;
• how quickly the generator starts;
• how fuel is managed;
• whether long outages have occurred;
• whether there is an automatic transfer switch.

Some buildings power only lifts, corridors, water pumps and reception. Sockets inside the apartment remain dead. Others provide limited apartment power but do not permit air conditioning.

A basic home backup may include:

A UPS for the router is useless if the provider’s equipment in the building’s technical room loses power. The entire chain has to be tested or confirmed.

For a laptop with a good battery, a network UPS and phone power bank may be enough. A desktop workstation, multiple monitors or editing computer requires a larger power station or a building with proper apartment backup.

Choosing an apartment for working from home

A remote worker does not need to live in BKK1. A quieter apartment in BKK3, Toul Tom Poung, Boeung Trabek, Toul Kork or Sen Sok may offer more space, a better desk and less noise for the same price.

Priorities include:

• a dedicated work area;
• a door that can be closed;
• natural light without severe overheating;
• a stable fibre connection;
• reception from at least two mobile operators;
• generator coverage;
• effective air conditioning;
• quiet surroundings;
• a proper chair;
• enough desk space for a monitor;
• sufficient sockets;
• a nearby coworking option;
• reasonable travel time to in-person meetings.

A one-bedroom apartment is usually better than a studio for remote work. The desk can remain in the living area while the bedroom stays separate from work. For a couple on different schedules, a door allows one person to sleep while the other is on a call.

A well-planned studio can still work on a limited budget, but it needs a real desk, storage and some visual separation between the bed and workspace. A small decorative dining table is not an eight-hour workstation.

Check noise both in the morning and evening. Construction may start early while a rooftop bar may run late. Noise-cancelling headphones can help with calls, but they do not restore concentration.

Pay particular attention to outdoor air-conditioning units, water pumps, generators, lifts and adjacent bars. Low-frequency noise is easy to miss during a ten-minute viewing.

Coworking spaces: useful even with a good apartment

A coworking membership is not only for people with poor home internet. It provides a backup workplace, meeting rooms, a professional environment and a physical boundary between work and home.

Phnom Penh has both local and international operators. Workspace 1 at Factory Phnom Penh offers flexible options from around $35 a month in a larger creative and technology complex on National Road 2 in Mean Chey. Spaces and Regus offer coworking, dedicated desks, meeting rooms and private offices in several business centres.

International operators may charge considerably more for day access than a local operator charges for a basic monthly flexible membership. Published prices vary by format, access and contract, which is why “the price of coworking” cannot be reduced to one figure.

Before paying for a month, spend a trial day checking:

• actual speed and stability;
• phone booths;
• rules for calls;
• noise;
• air conditioning;
• chair quality;
• access hours;
• backup power;
• meeting rooms;
• parking;
• coffee and water;
• travel time from home;
• equipment security;
• whether a monitor can be stored;
• cancellation terms.

A coworking space 45 minutes away is a poor emergency backup. Ideally, keep one option within 10–15 minutes of home and another near clients or the business centre.

Using cafés as workspaces

Phnom Penh has many cafés with Wi-Fi, sockets and air conditioning. They are useful for a short work session but are not a substitute for professional infrastructure.

Cafés work well for:

• email;
• writing and research;
• a short non-confidential call;
• waiting between meetings;
• a change of environment;
• a temporary home outage.

They are poor choices for:

• conversations involving personal data;
• hours of video calls;
• financial administration;
• large uploads;
• recording clean audio;
• daily work without meaningful purchases;
• leaving equipment unattended;
• tasks requiring a second monitor.

Public Wi-Fi should not be treated as secure. Use a personal hotspot and VPN for banking, CRM access, client data and administrative systems.

There is also an etiquette issue. Buying one drink does not entitle someone to occupy a large table all day, conduct loud calls and connect several devices. For regular work, coworking is often both fairer and cheaper than constant café orders.

Time zones and working hours

Phnom Penh operates on UTC+7. It is four hours ahead of Moscow, five or six hours ahead of Central Europe depending on daylight saving, and six or seven hours ahead of London.

For teams in Russia, the schedule is convenient. The Cambodian morning can be used for focused work, with meetings taking place in the afternoon.

European working hours shift into the evening. Calls running until 6 p.m. Central European Time may finish around midnight in Phnom Penh. This can work, but it affects sleep, exercise, relationships and apartment choice.

The United States is more difficult. East Coast schedules often occupy the evening and night, while West Coast work may become almost entirely nocturnal.

Late calls make the following more important:

• a separate room;
• a quiet building;
• decent sound insulation;
• air conditioning that can run at night;
• a safe route home from coworking;
• no early-morning construction;
• a workable meal routine;
• lighting that does not disrupt post-work sleep.

A lower cost of living does not compensate for a destroyed sleep cycle. Phnom Penh is generally most convenient for work aligned with Asia, Russia, Australia and parts of Europe.

Protecting data and equipment

Remote workers often carry hardware and account access worth more than the monthly rent. Security should be part of housing selection.

Check:

• door locks;
• building access control;
• cameras;
• visitor procedures;
• safe storage;
• whether a laptop can be locked away;
• fire safety;
• risk of water leaks;
• contents insurance;
• replacement of lost access cards.

Never leave a laptop unattended in a café. In a tuk-tuk, keep the bag away from the open side and do not hold the phone over the road.

Digital protection should include:

• full-disk encryption;
• a password manager;
• multi-factor authentication;
• offline recovery codes;
• a separate work SIM;
• VPN;
• encrypted cloud backup;
• remote data deletion;
• a spare hardware security key;
• copies of key documents outside the laptop.

Banking, email and work access should not depend on a single SIM card. If the phone is lost, you need a recovery method that does not require returning to the country where the main number was issued.

Anyone working with medical, financial, government or regulated personal data should confirm that their employer permits permanent work from Cambodia and storage on the devices being used.

A realistic remote-work budget

Remote work from Phnom Penh can be inexpensive, but a reliable setup still requires some initial investment.

Someone working entirely from home may spend around $40–80 a month on connectivity. Adding regular coworking and business-grade internet can raise the amount to $150–350.

Do not buy expensive furniture until the apartment has been tested. The desk may not fit in the lift, the landlord may object to replacing existing furniture or you may decide to move after one month.

For a one-year lease, negotiate the desk, chair and private line before signing. A landlord is more likely to include furniture as part of the deal before receiving the deposit.

For business-critical remote work, these costs should be viewed as continuity expenses rather than ordinary lifestyle spending. One lost client call may cost more than a month of backup mobile data.

Visas, taxes and employer approval

Foreign income does not remove immigration and tax questions. Working for overseas clients and receiving money into a foreign account does not automatically create a right to live and work indefinitely in Cambodia.

You may need to examine:

• the basis for long-term residence;
• whether a work permit is required;
• Cambodian tax residence;
• whether the arrangement is employment or self-employment;
• Cambodian payroll and tax treatment;
• permanent-establishment risk for the foreign company;
• your employer’s remote-work policy;
• insurance;
• data-protection requirements;
• business registration for freelancing.

One test of Cambodian tax residence is presence for more than 182 days in any 12-month period. A resident’s foreign-source salary may require Cambodian tax analysis.

An employer may support occasional remote work while prohibiting permanent work from a country where it has no legal entity. The reasons include payroll, employment law, data protection and corporate tax risk.

A freelancer with several clients may be carrying on a business. Registration, income tax, patent tax, VAT and invoicing may then need to be considered.

This article is informational and does not replace individual tax, legal or immigration advice. Obtain written approval from the employer and professional advice before relocating.

A seven-day setup test

On day one, obtain two SIM cards from different operators and test them in the apartment, on the balcony and in the proposed work area.

On day two, run several video calls on home Wi-Fi and separately through mobile tethering. Compare sound, delay and stability rather than speed alone.

On day three, ask management exactly how the generator works. Disconnect your own router from mains power and test the UPS safely. Do not interfere with building equipment.

On day four, visit two coworking spaces: one close to home and one near the business district or clients.

On day five, configure the VPN, recovery codes, cloud backup and remote wipe. Save support contacts for the provider and building management.

On day six, work a full normal day from the apartment. Use your real combination of video calls, cloud storage, uploads and background services.

On day seven, simulate failure of the primary line. Switch to mobile data, continue working and measure how long the transition takes.

After this week, you will know whether the apartment is suitable. A viewing-time speed test cannot provide the same information.

Red flags in a home-work setup

Consider rejecting the apartment or changing the terms if:

• the landlord refuses a private internet line;
• management cannot explain what the generator powers;
• Wi-Fi slows sharply in the evening;
• mobile data does not work indoors;
• a major construction site is starting nearby;
• there is no sensible place for a desk;
• the work area takes direct western sun;
• the air conditioner is old and noisy;
• sockets overheat;
• fire procedures are unclear;
• the provider demands a long contract with no relocation exit;
• “included internet” has no stated speed or provider;
• coworking call booths are always unavailable.

Another concern is a building where dozens of residents work online through one shared line. Cheap included Wi-Fi does not compensate for repeated evening failure.

Who Phnom Penh suits as a remote-work base

The city is well suited to someone working in Asian, Russian or European time zones, using standard cloud tools and willing to maintain two independent connections.

It can work particularly well for:

• remote employees paid in foreign currency;
• online-business owners;
• consultants with Asian clients;
• developers;
• designers;
• marketers;
• e-commerce professionals;
• online teachers;
• small distributed teams.

It is more difficult for someone tied to West Coast US hours, daily uploads of hundreds of gigabytes, strict ultra-low-latency requirements or a corporate ban on working from Cambodia.

It also does not suit a person who intends to work only from cafés and refuses to maintain backup systems. Phnom Penh provides the components, but the user has to assemble resilience.

Conclusion: reliability comes from redundancy, not headline speed

Phnom Penh has sufficient fibre internet, mobile connectivity and workspace options for most digital professions. In 2026, remote workers can access fibre, 4G/5G, local coworking spaces and business centres run by international operators.

One line and one operator are not a professional setup. The minimum sensible configuration is home fibre, a SIM from another operator, a power bank or UPS and a nearby coworking option.

Before leasing, run an evening video call, test upload speed, VPN, mobile reception and the generator. A neighbourhood name and advertised download speed do not describe the performance of a particular apartment.

Coworking remains useful even with a good home office. It provides meeting rooms, emergency internet, a professional community and separation between work and home.

Basic connectivity can cost under $100 a month. A more professional setup with coworking, a business package and a portable power station costs more, but remains modest compared with lost clients and failed workdays.

Remote work from Phnom Penh becomes comfortable when three questions already have answers: where you switch when fibre fails, what keeps the router powered and where the next call will take place if the apartment temporarily cannot be used.
