Install Your eSIM Before Leaving India
Install your HelloRoam Southeast Asia eSIM at home in India over Wi-Fi before your departure. Flights from Mumbai, Delhi, Bangalore, Chennai, and Hyderabad connect to Bangkok, Singapore, Kuala Lumpur, and Bali multiple times daily. Having your eSIM ready means you are connected the moment you land, with no SIM shop queue and no hidden airport charges.

Regional eSIM vs Local SIMs vs Indian Carrier Roaming for Southeast Asia Travel
Southeast Asia is India's most popular outbound travel region. A regional eSIM offers the best value and convenience for multi-country Southeast Asia trips compared to buying SIMs at each destination or using Jio, Airtel, or Vi international roaming.
—
One plan covers Thailand, Malaysia, Singapore, Vietnam, Bali, and more. Buy before leaving India. No SIM hunting at Suvarnabhumi, Changi, or Ngurah Rai airports. No registration paperwork. Best value for multi-country Southeast Asia circuits.
—
Separate SIM for Thailand, Malaysia, Vietnam, Indonesia, and each additional country. Airport SIM counters at Suvarnabhumi and Changi are convenient but expensive. Registration requirements vary by country. Managing multiple SIMs across a two-week circuit adds hassle.
—
Jio, Airtel, and Vi international roaming packs for Southeast Asian countries carry per-day charges for each country. A two-week trip through Thailand, Malaysia, Singapore, and Bali can accumulate significant roaming fees. A single regional eSIM plan is almost always more cost-effective.

Best Times for Indian Travellers to Visit Southeast Asia
Thailand is best visited November through April during the dry season. This aligns well with Indian winter holidays, Diwali travel, and the Christmas-New Year period. The rainy season from May through October brings lower hotel prices but wet weather.
Bali is best April through October in the dry season. The wet season from November through March can bring heavy afternoon rains.
Singapore and Malaysia have no strong seasonal variation as equatorial countries. Any month works, though November through January can see heavier rains.
Vietnam's north (Hanoi, Ha Long Bay) is best October through April. Vietnam's south (Ho Chi Minh City, Mekong Delta) is best November through April.
Indonesia's off-peak season from May to September is often the best for Bali. The Christmas-New Year peak season sees higher prices and crowds.
