Asia covers an enormous range of mobile network quality, from Japan's world-leading 5G to remote mountain areas in Central Asia with no signal at all. A HelloRoam Asia regional eSIM keeps you connected across the most popular travel corridors without buying a new SIM at each border.
East Asia (Japan, South Korea, Taiwan, Hong Kong) has some of the world's fastest and densest mobile networks. Japan's local partner networks operate near-universal 5G in populated areas. South Korea's local partner networks have strong 5G nationwide. These countries have excellent indoor coverage in malls, hotels, and transit systems.
Southeast Asia (Thailand, Vietnam, Singapore, Indonesia, Philippines, Malaysia, Cambodia, Laos, Myanmar) is the most popular multi-country travel corridor in Asia. Coverage quality varies widely. Singapore has near-perfect 4G and 5G. Thailand's local partner networks cover cities and resort areas well. Vietnam's urban coverage is strong with gaps in rural highland areas. Indonesia's coverage is excellent in Java and Bali but sparse in outer island provinces.
South Asia (India, Sri Lanka, Nepal, Bangladesh, Bhutan, Pakistan, Maldives) has varied coverage. India's local partner networks have rapidly expanded 4G and 5G in cities, but rural mountain states and Northeast India have significant gaps. Nepal's Kathmandu Valley has good 4G but trail coverage in the Himalayas is very limited. Sri Lanka's main tourist areas are well-covered.
Central Asia (Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan) has functional urban 4G in capitals but very limited coverage in rural and mountain areas. The Silk Road tourism circuit passes through areas with gaps.
