旅客應該選擇亞洲 SIM卡還是eSIM？
HelloRoam eSIM掃描QR code即可啟用，從HK$50.78起連接本地網絡服務商 4G/5G網絡。傳統實體SIM卡需要到亞洲機場排隊購買，啟用過程費時費力。eSIM在出發前幾分鐘就能設定好，落機後數據立即生效。
HelloRoam eSIM購買時無需護照或身份證明，用任何國際信用卡即可完成付款。在亞洲門市買實體SIM卡通常要求出示護照登記，部分國家還需填寫表格。eSIM全程線上完成，QR code直接發送到電郵，無需到店。
eSIM直接寫入手機，無需取出原有SIM卡，保留原本號碼同時使用亞洲本地數據。實體SIM卡需要SIM卡針和卡托，換卡時容易遺失原卡。旅程結束後eSIM自動停用，無需歸還任何實體卡片。
實體SIM卡價格參考各地機場及門市售價。已於2026年1月驗證

eSIM Coverage Guide for Asia Travel
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 NTT Docomo, SoftBank, and au operate near-universal 5G in populated areas. South Korea's SK Telecom, KT, and LG Uplus 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 AIS, DTAC, and True Move 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 Jio, Airtel, and Vi 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.
When crossing Asian borders, your phone connects to the local carrier automatically. At major airports in Bangkok, Tokyo, Singapore, and Seoul, your data activates within seconds of landing.
- One plan covers 48 countries across Asia
- Japan, South Korea, and Singapore offer world-class 5G networks
- Southeast Asia is the most popular multi-country travel corridor
- Automatic carrier switching at each border crossing
- Mountain and rural areas in South and Central Asia have limited coverage
- Download offline maps before remote treks and island hops

亚洲 eSIM旅遊貼士
Japan Has Excellent Indoor Coverage
Japan's mobile networks are among the world's best and have very strong indoor coverage, including in subway systems, high-speed Shinkansen trains, and mountain tunnel roads. NTT Docomo's network reaches even remote rural areas and mountain villages. Your HelloRoam eSIM works reliably throughout Japan.
Southeast Asia Island Hops Lose Data at Sea
Ferry routes between Thai islands (Koh Samui, Koh Phangan, Koh Tao), Indonesian islands (Bali to Lombok, Gili Islands), and Philippine islands have no data coverage once you are offshore. Download maps, guesthouse addresses, and transport details before boarding any island ferry.
Nepal and Himalayan Treks Have No Coverage on Trails
Nepal's Kathmandu has reasonable 4G from Ncell and Nepal Telecom. Everest Base Camp, Annapurna Circuit, and Langtang trails have no mobile coverage beyond the first few kilometers. Download your trekking maps, permits PDF, and emergency contacts before your trek departs.
Check if China Requires a Separate Plan
China has very specific network access rules and a separate internet environment including the Great Firewall. Most Asia regional plans do not include China or have limited access. If your trip includes mainland China, verify your plan's China coverage and whether you need a separate plan for the Great Wall Corridor.
India's Rural Mountain States Have Signal Gaps
India's Northeast states (Arunachal Pradesh, Nagaland, Manipur, Mizoram) and parts of Himachal Pradesh, Sikkim, and Ladakh have very limited coverage. Jio, Airtel, and Vi have expanded rapidly but remote highland areas still lack signal. Download offline content before entering these regions.
Singapore Works as a Reliable Transit Hub
Singapore has near-perfect 4G and 5G coverage from Singtel, StarHub, and M1. Changi Airport is one of the best-connected airports in the world. Use Singapore transit stopovers to confirm your eSIM is working correctly before heading to countries with lower coverage quality.
Emergency Numbers Vary Across Asia
Emergency numbers differ by country across Asia. Japan uses 110 (police) and 119 (fire/ambulance). South Korea uses 119 (fire/medical) and 112 (police). Thailand uses 191 (police) and 1669 (ambulance). India uses 112 for all emergencies. Save the correct emergency number for each country you visit.

Best Times for Asian Travel Data
Asia's travel seasons vary dramatically by subregion. Southeast Asia's dry season from November to April is peak travel time for Thailand, Vietnam, Cambodia, and Laos. Network demand peaks in popular tourist areas like Bangkok, Chiang Mai, Bali, and Hoi An during these months.
Japan's cherry blossom season (late March to early April) and autumn foliage (mid-October to November) are peak travel periods with crowded networks in tourist areas. Book high-speed Shinkansen routes in advance and download entertainment for train travel.
Monsoon season across South and Southeast Asia runs roughly June to October. Flooding and storm damage can affect tower infrastructure in rural areas. Urban coverage in main cities remains reliable. The Indian subcontinent's monsoon runs June to September.
