Telecommunications in Cambodia

Telecommunications in Cambodia is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Telecommunications in Cambodia rather than just read about it. In short: Telecommunications in Cambodia include telephone, radio, television, and Internet services, which are regulated by the Ministry of Posts and Telecommunications. Transport and posts were restored throughout most of the country in the early 1980s during the People's Republic of Kampuchea regime after being disrupted under Democratic Kampuchea (Khmer Rouge).

Key takeaways

  • Telecommunications in Cambodia belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Telecommunications in Cambodia to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Telecommunications in Cambodia from memory before moving on to harder problems.

Reference excerpt

Telecommunications in Cambodia include telephone, radio, television, and Internet services, which are regulated by the Ministry of Posts and Telecommunications. Transport and posts were restored throughout most of the country in the early 1980s during the People's Republic of Kampuchea regime after being disrupted under Democratic Kampuchea (Khmer Rouge). In January 1987, the Soviet-aided Intersputnik space communications station began operation in Phnom Penh and established two-way telecommunication links between the Cambodian capital and the cities of Moscow, Hanoi, Vientiane, and Paris. The completion of the earth satellite station restored the telephone and telex links among Phnom Penh, Hanoi, and other countries for the first time since 1975. Although telecommunications services were initially limited to the government, these advances in communications helped break down the country's isolation, both internally and internationally. Today, with the availability of mobile phones, communications are open to all, though the country's former Prime Minister Hun Sen decreed that 3G mobile phones would not be allowed to support video calling.

Telephone

As of Q1 2020, Cambodia's mobile connection is at 21.4 million. Smart Axiata, a leading telecommunications company, in 2019 conducted a live trial of its 5G network with support from China's Huawei. The company said it expects to begin rolling out 5G services in Cambodia by the end of 2019. GSMA predicted that by 2025, Cambodia will have approximately 24.3 million total mobile connections, with smartphone connections up to 69%. The market is predicted to adopt 1.6 million 5G connections within 5 years from 2020. Even so, it's believed that 4G still has room for growth and will continue to be the majority network connection. The government state communications corporation is Telecom Cambodia, founded in 2006 as an expansion of the telecom operating department of the Ministry of Posts and Telecommunications.

Mobile Network Operators

Radio and television

As of 2019, Cambodian broadcasters were a mixture of state-owned, joint public-private, and privately owned companies.

Radio stations As of 2019, there were roughly 84 radio broadcast stations: 1 state-owned broadcaster with multiple stations and a large mixture of public and private broadcasters. Several international broadcasters are also available.

Phnom Penh

Provincial stations There are radio stations in each of the following provinces: Banteay Meanchey, Battambang, Kampong Cham, Kampong Thom, Kampot, Kandal, Pailin, Preah Vihear, Siem Reap, Sihanoukville and Svay Rieng.

Television Cambodia has 27 TV broadcast stations with most operating on multiple channels, including 1 state-operated station broadcasting from multiple locations, 11 stations either jointly operated or privately owned with some broadcasting from several locations. Multi-channel cable and satellite systems are also available. There is one Chinese joint venture television station with the Ministry of Interior. Several television and radio operators broadcast online only (often via Facebook).

Broadcast and cable networks

Provincial television stations Kandal Province - Broadcasting on channel 27, Bayon Television is Cambodia's only UHF channel. A private television company belonging to Prime Minister Hun Sen, it also operates Bayon Radio FM 95 MHz. It was established in January 1998. Mondulkiri - Established in 1999, relays TVK on channel 10. Preah Vihear - Established in 2006, broadcasts on channel 7. Ratanakiri - Established in 1993, relays TVK on channel 7. Siem Reap - Established in 2002, relays TV3 on channel 12.

Most viewed channels

Internet As of 2019, the number of internet users in Cambodia rose to 15.8 million, about 98.5% of the population. According to the Telecommunications Regulator of Cambodia (TRC), the number of registered SIM cards rose by 9.4 percent during the first half of the year, reaching 20.8 million. The SIM card market is saturated, with Cambodia now having more active SIM cards than people. According to TRC, there are six telecommunications firms in the country: Cellcard, Smart Axiata, Metfone, Seatel, Cootel, and qb. Three companies, Metfone, Cellcard, and Smart, account for 90% of users. TRC noted that, as of February 2019, Facebook had seven million users in Cambodia.

Internet service providers As of August 2025, the following are the active licensed telecommunications operators authorized to provide internet services in Cambodia, according to the Telecommunication Regulator of Cambodia:

Worked examples

Example 1 — a first encounter with Telecommunications in Cambodia

Start with the simplest possible case. Write down what Telecommunications in Cambodia claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Telecommunications in Cambodia before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Telecommunications in Cambodia ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Telecommunications in Cambodia

In research
Telecommunications in Cambodia appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Telecommunications in Cambodia in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Telecommunications in Cambodia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Telecommunications in Cambodia, so understanding it makes those chapters shorter.
In everyday life
Look for Telecommunications in Cambodia outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
