Vietnam is emerging as a leading hub for telecom and software development. With nearly 79.8 million internet users (78.8% of the population) and broad mobile coverage, digital services thrive here. Vietnam’s offshoring market has grown rapidly – reaching about USD 0.53 billion in 2023 with a 12.7% CAGR (2016–2023). Statista projects this market will hit USD 0.84 billion by 2028 (CAGR ~8.8%). Globally, providers like Kearney also recognize Vietnam: it ranks 7th in the world for outsourcing ability. In this booming environment, voip development companies in Vietnam are thriving. We at Designveloper help businesses harness these trends. Our team builds custom VoIP communication solutions tailored to each client’s needs.
The demand for VoIP and unified communications is soaring worldwide. For example, the global VoIP services market is forecast to grow from US$178.9 billion in 2025 to US$413.4 billion by 2032 (about 12.7% annual growth). Vietnam is riding this wave at home. According to market research, Vietnam’s IP telephony (VoIP) market is set to grow at about 12.1% CAGR through 2033. Remote work and digital transformation are driving this growth. As a result, businesses increasingly seek experienced developers to build robust VoIP apps and services. Vietnam’s strong engineering talent and fast networks make local firms well-positioned to deliver. For example, we implement modern VoIP protocols (like SIP and WebRTC) and scalable architectures to ensure high-quality voice and video calls over the internet.
Key Advantages of Vietnam as a VoIP and Software Hub
Skilled Workforce
Vietnam produces a large number of IT engineers. The country has a literacy rate of 96.1% and ranks 7th in Asia for English proficiency. This means our developers communicate well with international clients and have solid technical training.
Cost-Effective Labor
Wages in Vietnam are much lower than in Western countries and many regional peers. In fact, industry analysts note Vietnam offers some of the best value in labor costs worldwide. This allows companies to get high-quality VoIP development at competitive prices.
Modern Infrastructure
Vietnam’s telecom infrastructure is excellent. As of late 2024, 4G network coverage is ~99.8% and 5G service has launched (full nationwide 5G rollout is planned by 2030). This means VoIP solutions can work reliably anywhere in the country. High internet penetration (79.1% of the population, ~78.4 million users) also ensures end-users have stable connections for voice and video calls.
Government Support
The Vietnamese government actively promotes digitalization and tech innovation. Policies and incentives encourage R&D and infrastructure projects. This supportive environment helps VoIP developers (and our team) access resources and operate smoothly.
Global Ranking
Independent reports place Vietnam among the top outsourcing destinations. For instance, Kearney’s 2023 Global Services Location Index ranked Vietnam 7th worldwide. Knight Frank also highlights Vietnam’s rising role in offshoring and notes its strategic location near major Asian markets.
Many companies compare Vietnam to other outsourcing hubs like India, China, or the Philippines. Vietnam often wins on the combination of cost and quality. For example, Vietnam’s average IT salaries are significantly below those in China or the Philippines, offering cost savings of 30–60% on development costs. In practice, this means a business can hire skilled Vietnamese developers for much less than a similar team in India or Eastern Europe. This cost advantage, combined with strong English skills and a similar time zone to much of Asia, makes Vietnam a practical choice for VoIP software projects.

Vietnam’s VoIP Market and Infrastructure
Vietnam’s VoIP industry is expanding fast. Market analysts report the Vietnam IP telephony market (covering business VoIP services) will grow at about 12.1% CAGR from 2025 to 2033. This growth is driven by demand for advanced communication tools, digital government initiatives, and a shift to remote work. In concrete terms, businesses of all sizes in Vietnam are moving from old PBX systems to VoIP software and cloud phone systems. They want features like multi-channel call centers, mobile apps, and integration with CRMs – exactly the solutions we build.
Meanwhile, the country’s digital infrastructure greatly supports VoIP growth. According to We Are Social/DataReportal, Vietnam had 127 million mobile connections by early 2025 (126% of the population) and 79.8 million internet users. National coverage is strong: as of 2024, 4G networks cover virtually the whole country, and 5G has already launched in major cities. The government plans to have 5G nationwide by 2030. This means Vietnamese businesses and consumers can use high-speed internet and VoIP apps on laptops and smartphones almost anywhere. In practice, our VoIP applications run seamlessly on these networks, ensuring crystal-clear calls and video conferencing for users in Vietnam and abroad.
