Asia hosts the world's most advanced and some of the world's most limited mobile networks side by side.
NTT Docomo's near-universal 5G rollout and underground subway coverage in all major cities. South Korea's SK Telecom, KT, and LG Uplus have the highest 5G penetration rates globally. Singapore's three operators compete in a tiny but dense market with very fast speeds. Taiwan's Chunghwa Telecom has strong 5G in urban areas.
Southeast Asia varies from Singapore's excellence to Myanmar's rebuilding network infrastructure. Thailand's AIS leads in GSMA coverage rankings for the region. Vietnam's Viettel has grown rapidly with strong 4G in Hanoi and Ho Chi Minh City. Indonesia's Telkomsel reaches Java and Bali excellently but outer islands very poorly. The Philippines' Globe Telecom and Smart Communications have improved dramatically but typhoon-affected rural areas remain patchy.
South Asia's India is a rapidly evolving market. Jio launched 5G in 2022 and expanded to hundreds of cities. Airtel has strong 4G coverage in urban and semi-urban India. Rural India still has significant gaps, particularly in forested and mountain states. Nepal and Bhutan have very limited coverage outside capitals and major towns.
Central Asian networks are state-influenced and serve cities well but have almost no coverage in the vast rural steppes and mountain ranges that draw adventure travelers.
