eSIM Travel Tips for Asia
Install Before You Leave Dublin
Asia is a long-haul destination from Dublin. Flights to Bangkok, Tokyo, or Singapore typically connect through London, Dubai, or Amsterdam. Install your HelloRoam Asia eSIM over Wi-Fi before you leave Ireland. You land connected without needing to find and queue at an airport SIM counter.
EU Roaming Doesn't Apply in Asia
Your Three IE, Vodafone Ireland, Eir, or GoMo plan's EU Roaming allowance only works within the EEA. In Thailand, Japan, Bali, or any Asian destination, standard international roaming rates apply if you use your Irish carrier. A HelloRoam Asia eSIM is a more cost-effective option for data throughout Asia.
Thailand's Resorts and Cities Are Reliable
Bangkok, Phuket, Chiang Mai, and Koh Samui all have reliable 4G. AIS, DTAC, and True Move compete across all tourist areas. Beach resort zones are generally well-covered. More remote jungle and mountain areas can have weaker signal.
Japan Delivers Premium Connectivity
Japan is one of the most connected countries in the world. Tokyo's entire subway system has coverage including underground stations. The Shinkansen has in-train 4G and 5G throughout the route. Even rural and mountain areas in Japan generally have 4G coverage. It's a brilliant experience for any Irish traveller.
Download Offline Maps for Remote Bali Areas
Bali's main tourist areas including Seminyak, Ubud, and Canggu are well-connected. Remote eastern Bali, inland mountain areas, and less-visited parts of Lombok can have patchy signal. Download offline maps before driving anywhere remote on the island.
Network Coverage Across Asia
Japan: NTT Docomo, SoftBank, and au operate nationwide 5G and near-universal 4G LTE. Coverage quality is globally exceptional.
South Korea: SK Telecom, KT, and LG Uplus run dense 5G in all urban areas. Seoul's 5G penetration is among the world's highest.
Thailand: AIS, DTAC, and True Move compete across the country. AIS has the widest rural coverage. Bangkok has growing 5G.
Indonesia: Telkomsel dominates with widest coverage. Indosat and XL Axiata compete in urban areas. Bali and Java are well-covered.
Vietnam: Viettel has excellent rural reach by regional standards. Ho Chi Minh City and Hanoi have strong 4G.
Philippines: PLDT and Globe Telecom dominate. Manila and Cebu have solid 4G.
Cambodia: Smart and Metfone cover Phnom Penh and Siem Reap. Rural areas are more limited.

Regional eSIM vs Irish Carrier Roaming for Asia Travel
EU Roaming Regulation does not apply in Asia. Using your Three IE, Vodafone Ireland, or Eir plan in Thailand, Japan, or Bali means paying standard international roaming rates. A HelloRoam Asia eSIM is typically far more cost-effective for any Asian holiday.
| Category | HelloRoam Regional Asia eSIM Recommended | Individual country SIMs | Irish carrier international roaming |
|---|---|---|---|
| Typical cost | — | — | — |
| Details | One plan covers Thailand, Japan, South Korea, Bali, and more. Buy before leaving Ireland. No SIM hunting at Asian airports. Much better value than Irish carrier international roaming rates for Asia. | Separate SIM required for each country. Airport SIM counters have queues. Registration requirements vary. Managing multiple SIMs adds hassle on a multi-country trip. | Three IE, Vodafone Ireland, Eir, and GoMo charge standard international roaming rates in Asia. Daily rates can be significant. A two-week Japan plus Thailand trip can accumulate hundreds of euros in carrier roaming charges. |
Prices approximate as of . Actual savings vary.
Best Times for Irish Travellers to Visit Asia
Thailand is best November through April in the dry season. This aligns with Irish winter sun seekers looking for warmth during the colder months. Japan's spring cherry blossom season (late March to early May) and autumn foliage (October to November) are the most popular periods.
Bali's dry season is April through October. Vietnam's south is best November through April.
Irish summer holidays from June through August see significant travel to Bali and Thailand, though these fall during shoulder or monsoon season in parts of Southeast Asia.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
