Best eSIM for Asia 2026: Airalo, Saily, Ubigi & Holafly

Travelling from Australia to Japan, Thailand, Bali, Vietnam, Singapore, Malaysia or Sri Lanka? A prepaid travel eSIM can provide mobile data without relying on expensive daily roaming passes, but the cheapest-looking plan is not always the best value. Our October 2026 comparison finds that Airalo is a strong starting point for fixed-data regional trips, Saily suits itineraries needing its wider Asia–Oceania coverage, Ubigi is a practical alternative with clear network listings and tethering, and Holafly is worth considering for people who prioritise unlimited phone data—subject to its fair-use and hotspot restrictions.

No provider wins for every itinerary. Travellers who spend two weeks in one country may pay less with a country-specific eSIM or a local operator, while a family using laptops and tablets may prefer a larger fixed-data allowance instead of an “unlimited” plan with a restricted hotspot.

Quick answer: which Asia travel eSIM should you choose?

Traveller	Strong starting option	Why—and what to verify
Two- or three-country holiday with moderate data use	Airalo Asialink	10 GB/30 days advertised at US$25; check that every country is among its 18 covered destinations.
Asia–Oceania itinerary, or longer trip	Saily Asia & Oceania	22 destinations, with options including 25 GB/60 days; region includes Australia and New Zealand as well as several Asian countries.
Need named local networks and hotspot sharing	Ubigi Best Asia	10 GB/30 days at US$28, with named partner networks and data sharing; check the local AUD checkout price.
Heavy phone-data user who dislikes fixed quotas	Holafly Asia	Unlimited phone data with 7-day plans listed at US$27.50; local network fair-use controls and 1 GB/day hotspot allowance apply.
Long stay in one country	Country-specific or local-carrier eSIM	Can offer better local value or voice/SMS, but identity registration and activation conditions vary.
Short stopover and frequent Australian-number calling	Australian carrier’s roaming pass	Simpler for eligible customers; confirm destinations, daily price, data limits and renewal triggers.

These are editorial use-case recommendations, not rankings of measured network speed, reliability or customer service. Coverage depends on the particular plan and partner networks. Airalo’s package list, Saily’s region page, Ubigi’s specific package and Holafly’s Asia product underpin the comparison.

Asia eSIM price comparison: what Australians may pay

To make unlike offers easier to assess, we selected identifiable plan sizes rather than relying on “from” prices. The AUD conversion below is indicative only for USD-priced options; it is not a real-time provider checkout or promise of a particular bank exchange rate.

Provider and plan	Advertised USD	Indicative AUD	Data / expiry
Airalo Asialink	US$25.00	~A$35.90	10 GB / 30 days
Airalo Asialink	US$39.00	~A$56.00	20 GB / 30 days
Ubigi Best Asia	US$28.00	~A$40.21*	10 GB / 30 days
Saily Asia & Oceania	US$35.99	~A$51.68	10 GB / 30 days
Saily Asia & Oceania	US$48.99	~A$70.35	25 GB / 60 days
Holafly Asia	US$27.50	~A$39.49	Unlimited phone data / 7 days, subject to policy
Holafly Asia	US$73.90	~A$106.12	Unlimited phone data / 30 days, subject to policy

*Important Ubigi currency exception: Ubigi also displayed a direct AU$48 retail price for its 10 GB/30-day Best Asia product on its Australian-dollar listing. A simple currency conversion of US$28 would be approximately A$40.21, but the provider’s chosen AUD retail price can differ. Confirm which currency and price actually appears before paying. See Ubigi’s Australian-dollar listing.

1. Airalo Asialink: a competitive fixed-data starting point

Best suited to: a traveller visiting two or more supported Asian countries who wants a clear finite data allowance and the option to top up.

Airalo advertises an 18-country Asia region spanning Japan, South Korea, China, India, Sri Lanka, Thailand, Vietnam, Singapore, Malaysia, Indonesia, Cambodia and other destinations. Its public package list includes 10 GB for 30 days at US$25 and 20 GB for 30 days at US$39. An inexpensive plan can be ideal for maps, messaging, short videos, email and browsing when heavy streaming is limited.

Advantages: useful spread of Asian destinations; fixed, understandable data quotas; app-based setup and top-up options; no need to buy a new SIM after each included border crossing. Airalo says the validity period of its Asialink package begins when it connects to a supported network in the coverage area, so installing the profile in Australia need not automatically use travel days.

Important limitations: the listed regional plan is data-only, so ordinary mobile calls and SMS are not included; internet apps such as WhatsApp can use the connection. Some remote areas may have weak signal, and available 5G depends on handset and partner network. The plan does not cover every country in Asia—check your full route, not just the word “Asia”. Airalo’s Asialink country and validity list and voice/SMS guidance explain those conditions.

2. Saily Asia & Oceania: useful for a broader itinerary

Best suited to: travellers moving across several Asian destinations and Oceania, or people who need a longer expiry period for a planned journey.

Saily’s Asia & Oceania regional listing covers 22 destinations, including Sri Lanka, India, Japan, Thailand, Malaysia, Singapore, Indonesia, Vietnam, China, Hong Kong, Australia and New Zealand. Its listed packages include 3 GB/30 days at US$12.49, 10 GB/30 days at US$35.99 and 25 GB/60 days at US$48.99.

A wider country list can simplify a route such as Sydney → Singapore → Thailand → Vietnam → Japan, although Saily’s particular plan must still be checked for every stop. The 25 GB/60-day option may also be more convenient than renewing a 30-day bundle on a longer trip.

Important limitations: the regional packages are described as data-only, not ordinary mobile voice and SMS. Saily offers separate calling-related features on certain other products, so do not assume those features apply to this regional package. Refund eligibility changes once a plan is installed or activated. See Saily’s regional-plan help and refund policy.

3. Ubigi Best Asia: a strong option for people who need tethering

Best suited to: travellers who need to share their mobile internet with a laptop or tablet and value a published list of local roaming networks.

Ubigi’s Best Asia product lists 10 GB for 30 days at US$28, and explicitly allows data sharing. Its supported networks include NTT Docomo and KDDI in Japan, AIS and True Move in Thailand, Mobitel and Hutch in Sri Lanka, and specified partners in Vietnam, Singapore and other destinations. These are advertised roaming-partner arrangements, not proof of signal at a particular hotel or beach.

Ubigi says the eSIM can be installed on a compatible unlocked device, with its Smartstart activation beginning on arrival in a covered destination. The company also says the eSIM profile is reusable across a larger network of products, with data top-ups available via its app.

Important limitations: the service is primarily data-only, not a substitute for an Australian number receiving regular SMS or voice calls. The Australian-dollar retail quote may be higher than converting the USD-listed amount using an independent exchange rate. The number of covered countries and the named networks should be checked for the exact plan at purchase. Ubigi product and network list.

4. Holafly Asia: unlimited data, but mind the hotspot rule

Best suited to: people who expect frequent navigation, video streaming or large personal data usage on their phone, but do not need unrestricted tethering to a laptop or multiple family devices.

Holafly’s Asia plan offers day-based “unlimited” phone data. On 17 October, its public price table showed 7 days at US$27.50 and 30 days at US$73.90. The region covers 16 listed destinations, including Japan, Thailand, Sri Lanka, Malaysia, Indonesia, China, Singapore and Vietnam.

Unlimited does not guarantee unlimited speed. Holafly explains that local network fair-usage policies can temporarily reduce speeds after heavy data consumption. The Asia product also lists a separate 1 GB-per-day hotspot allowance: a 7-day plan therefore offers a total potential 7 GB of shared data, not unlimited hotspot use. For a family hotspot or remote worker, this limitation may matter more than the phone-data marketing claim.

Another essential detail: India is not shown in Holafly’s 16-country Asia regional coverage list, even though India appears in some of its separate country-specific or backup-connectivity products. A tourist travelling to both India and Thailand should verify that the precise regional product—not a different Holafly feature—covers the whole journey. See Holafly Asia country list and hotspot terms, plus its fair-use explanation.

Country-by-country guide: Japan, Thailand, Bali, Vietnam, Singapore, Malaysia and Sri Lanka

Even when a package covers the country, coverage can differ substantially by the local partner network, terrain and handset. Review maps and service terms, especially when travelling away from large cities.

Destination	What to look for	Planning note
Japan	Good urban coverage and rail navigation; check coverage beyond Tokyo/Osaka	Most compared regional products list Japan; Ubigi lists NTT Docomo/KDDI partners for its Best Asia package.
Thailand	Coverage in Bangkok, Chiang Mai and island destinations; adequate hotspot for transfers	Airalo, Saily, Ubigi and Holafly regional listings include Thailand.
Indonesia / Bali	Reliable resort and town service; check partner networks for more remote areas	“Bali” uses an Indonesia country listing; boats and remote islands can be coverage gaps.
Vietnam	Coverage beyond Hanoi, Ho Chi Minh City and Da Nang	All four products list Vietnam, but speed and rural performance cannot be established from a country list alone.
Singapore	Short stopover versus full trip; airport activation and transit connectivity	A brief stop may not justify a large regional bundle if Wi-Fi or an existing roaming pass is sufficient.
Malaysia	Kuala Lumpur/Penang coverage versus islands or rural regions	Regional eSIMs can help when continuing onwards to Thailand or Singapore.
Sri Lanka	Partner networks along a multi-region trip, including inland areas	Airalo lists Sri Lanka; Ubigi names Mobitel/Hutch; Holafly lists several Sri Lankan partners, but service at particular beaches is not guaranteed.
India	Explicit regional inclusion and any applicable local activation requirements	Airalo, Saily and Ubigi include India in their checked offerings; do not assume Holafly’s 16-country Asia package does.
China	Supported carrier and access to the apps and websites you rely on	International roaming eSIM traffic may be routed differently from local networks, but access to specific services is not guaranteed; check local rules.

One-country eSIM vs regional eSIM: which is better value?

A local-country eSIM is often a sensible first comparison if the holiday consists entirely of Bali, Japan or Thailand. A country-specific bundle may include a larger data quota or a preferred network at a lower price. In some destinations, a local mobile operator may also offer a phone number or domestic calls, although SIM registration rules and tourist eligibility can apply.

A regional Asia eSIM becomes more attractive when multiple borders are involved. Installing one profile in Australia and retaining it through several included countries reduces activation friction and may avoid running out of data between a late flight and a hotel check-in.

However, more countries does not automatically mean better value. A product that lists 22 destinations is not necessarily more reliable in Japan than one listing 18. Choose by the places actually visited, available partner networks, duration, expected data use and final price.

eSIM versus Australian roaming: worked holiday examples

Many Australian mobile plans offer a daily international roaming feature. Published comparisons describe eligible Vodafone and Optus products at around A$5 a day in selected destinations, and Telstra’s International Day Pass at A$10 a day in many destinations. Eligibility and conditions differ by postpaid/prepaid plan and country, so confirm the current terms with your provider rather than assuming the quoted pass automatically applies.

Illustrative trip	Roaming at A$5/day	Roaming at A$10/day	Alternative
3 days in Singapore	A$15	A$30	A small local eSIM or roaming pass may be competitive, depending on eligibility.
10 days in Thailand	A$50	A$100	Airalo regional 10 GB was ~A$36 at the stated conversion; a Thailand-only plan may be cheaper.
21 days through three countries	A$105	A$210	A regional 20 GB or 25 GB bundle can cost less, if its inclusion fits actual usage.

The roaming figures are arithmetic scenarios assuming an eligible pass is triggered on every day of the trip, not carrier quotes for a specific account. Charging periods and daily reset times vary. For official Australian carrier information, consult Telstra’s International Day Pass summary and the current international roaming sections of Optus and Vodafone.

How much data do you actually need in Asia?

Data usage varies dramatically with automatic photo backups, streaming quality, video calls, tethered laptops and app updates. The following are planning categories rather than measured daily usage rates:

Usage style	Suggested starting budget	Examples
Light	1–3 GB for a short trip	Maps, messages, restaurant searches, occasional email
Moderate	5–10 GB for 1–2 weeks	Frequent maps, photos shared over data, social browsing
Heavy	20 GB or more for 2–4 weeks	Regular video, cloud uploads, mobile hotspots or work communications
Very heavy or shared	Compare a large fixed plan, local carrier or hotspot policy	Video conferences, multiple devices, continuous uploads

Disable large automatic cloud backups over mobile data and download offline maps, playlists and entertainment while on trusted Wi-Fi. A “10 GB” product is not equivalent to unlimited daily streaming, but it may comfortably cover most routine navigation and communication for a careful traveller.

Keep your Australian number for banking codes and calls

One of the most common mistakes is buying a travel eSIM without checking whether it includes ordinary voice calls and SMS. Many low-cost travel packages supply only mobile data. WhatsApp, Signal, FaceTime Audio and other internet-based apps may work over that data, but they are not the same as being able to receive a conventional text message at your Australian mobile number.

On a supported unlocked dual-SIM phone, a useful arrangement is to retain your Australian SIM or eSIM for your usual number and select the travel eSIM for mobile data. Before departure:

Confirm whether your Australian carrier permits international SMS reception and what it costs.
Check whether enabling the Australian line overseas can trigger a roaming fee, especially if you make or answer a call, send a message or use data on that line.
Set the travel eSIM as the mobile-data line after arrival and disable any unwanted automatic data switching.
Turn off data roaming on the Australian line if that is needed to prevent unplanned usage, while following the home carrier’s guidance on receiving codes.
Set up bank-app authentication, backup verification methods and trusted-device access before leaving Australia.

Receiving SMS is not guaranteed on every roaming arrangement or in every destination. Apple confirms that supported phones can use a home number alongside a second travel eSIM. See Apple’s international travel eSIM guide and dual-SIM documentation.

How to install a travel eSIM on iPhone

Check compatibility and carrier lock: a modern iPhone with eSIM support still needs to be permitted to use the selected provider. Specific iPhone models sold in different regions have different SIM arrangements.
Buy the right package: verify the country list, plan duration, included data, hotspot allowance, activation window and refund conditions.
Use reliable Wi-Fi before departure: download the provider app or scan its QR code according to the instructions supplied.
Add the mobile plan: on supported iOS versions, open Settings → Cellular or Mobile Service → Add eSIM, then follow the QR/app instructions.
Label the lines: use names such as “Australia” and “Asia Travel”, so it is clear which one is selected for calls, texts and data.
After landing: switch the mobile-data line to the travel eSIM and enable data roaming on that travel plan only if required by its provider; keep the Australian line’s settings appropriate to your roaming arrangement.
Test before leaving the airport: load a webpage, open maps and check whether the eSIM actually connects to a supported mobile network.

Some providers’ packages begin counting validity only when they first connect to a covered local network. Others can be time-limited after installation or manual activation. Do not install too far ahead without reading the specific validity rule. NextNews also has a general iPhone eSIM activation walkthrough.

How to install a travel eSIM on Samsung Galaxy or Google Pixel

On supported Galaxy devices, the route is generally Settings → Connections → SIM manager → Add eSIM. On compatible Google Pixel models, Google describes Settings → Network & internet → SIMs → Add SIM → Set up an eSIM. Menu labels may differ with model, Android version and regional firmware.

Check that the phone is SIM-unlocked and supports the provider’s network. A phone displaying an EID identifier is a useful sign that eSIM capabilities are present, but it does not itself establish compatibility with every purchased plan. Google’s eSIM guide, dual-SIM instructions and the handset manufacturer’s support page should be checked before payment.

Hotspot, 5G and “unlimited” eSIMs: three traps

1. Unlimited phone data is not always unlimited high-speed data

Read the fair-usage policy and any temporary speed reductions imposed by partner networks. A provider may sell an unlimited-data product while still allowing the local carrier to slow speeds after substantial use. A slower connection can make work calls or video uploads unreliable even if basic messaging continues.

2. Hotspot allowances may be a separate limit

Holafly’s checked Asia product lists 1 GB of hotspot sharing per day. Ubigi advertises data sharing from its fixed allowance. Some other plans may restrict tethering or count shared data against the same total. Never assume “unlimited” also means an unlimited laptop hotspot.

3. 5G on the marketing page does not guarantee 5G everywhere

A device and its subscribed plan must support the relevant bands and roaming arrangements, and the local network must provide coverage at the location. A 4G connection with strong coverage can be more useful than intermittent 5G at a remote beach or along a highway.

Refunds, activation and account security

eSIMs are digital products, and refund terms can differ from ordinary retail purchases. For example, Saily says unused and uninstalled plans may qualify for a full refund within 30 days, while activated or largely used plans have more restricted terms and may be assessed individually. Other providers set their own validity and technical-failure processes.

Take screenshots or keep emails showing the exact product, supported countries, quota, expiry and refund policy at purchase. Install only through your selected provider’s genuine app or activation details. A QR code can be sensitive activation information, so do not post it publicly or share it with strangers.

Mobile roaming eSIMs may route internet traffic through infrastructure outside the country visited. For banking, medical, workplace or sensitive communications, use the organisation’s security controls and avoid assuming a travel eSIM is a privacy or VPN service. Remote workers should confirm that employers permit the connection and country of access.

Seven things to check before buying

Every country on your route: include overnight stops and any planned border crossings; do not assume a product called Asia includes all of Asia.
Plan start and finish: verify whether validity starts on installation, manual activation or first supported network connection.
Actual checkout total: compare billing currency, taxes, discount codes, transaction fees and the AUD conversion.
Data versus voice: work out whether the plan includes a phone number, calls, SMS or data only.
Hotspot limits: confirm whether a laptop or companion device can share data and how much.
Supported local networks: research expected coverage where you are actually staying, including islands and rural regions.
Top-up and support: check whether you can buy more data from an app, how refunds work and what happens if activation fails.

Three sample itineraries: our editorial picks

Trip A: 10 days in Japan and South Korea

Start by comparing Airalo’s 10 GB/30-day regional product and Ubigi’s Best Asia package; both include the two countries on their checked lists. Pick by actual network coverage, hotspot needs and final AUD price. A single-country Japan plan may be cheaper if South Korea is only a very short stopover.

Trip B: 18 days through Thailand, Vietnam and Sri Lanka

Airalo, Saily, Ubigi and Holafly include these three destinations in their checked regional plans. Moderate users can compare 10 GB or 20 GB fixed-data options. Heavy users may prefer Holafly phone data, but anyone sharing data with a laptop should assess its daily hotspot cap. For Sri Lanka, check partner network coverage along the intended coast or inland travel route rather than relying on the country name alone.

Trip C: 35 days across Singapore, Malaysia, Japan and New Zealand

Saily’s Asia & Oceania coverage may be a better starting point than an Asia-only package because New Zealand is listed, and the 25 GB/60-day option can span a longer trip. Confirm the precise coverage and activation of the selected product and compare against separate country eSIMs before purchasing.

Frequently asked questions

Which is the cheapest regional eSIM for Asia?

For the matched 10 GB/30-day products checked on 17 October 2026, Airalo’s US$25 advertised price was below Ubigi’s US$28 and Saily’s US$35.99. That does not make Airalo the cheapest for every country, smaller bundle or promotional checkout price.

Is Holafly really unlimited?

It sells unlimited phone data, but partner fair-use restrictions can temporarily reduce speed and the checked Asia plan separately limits hotspot sharing to 1 GB per day. Verify the current product terms.

Can I keep my Australian mobile number?

Often yes, using dual-SIM on a compatible unlocked phone and keeping the home line active. Ordinary calls and SMS will be governed by your Australian carrier’s roaming rules; the data-only travel eSIM does not transfer your phone number.

Can I receive bank verification SMS while overseas?

It depends on the Australian provider, destination and the particular service. Check roaming eligibility and set up alternative secure verification before departure. A separate data-only travel eSIM will not itself receive texts sent to your Australian number.

Is a regional eSIM better than a local SIM in Bali?

Not necessarily. A Bali-only trip may be served more economically by an Indonesia-specific eSIM or a local carrier; the regional product is often more convenient if travelling onwards to other countries.

Can I use the eSIM in China?

Some compared plans list mainland China, but specific app accessibility, network routing and local regulations may differ. Check your intended services and the provider’s current terms rather than assuming any eSIM bypasses restrictions.

Should I install the eSIM in Australia?

Usually it is convenient to install over Wi-Fi before travelling, but first confirm when the purchased plan starts counting its validity. Many regional plans start on first covered network connection; other plans may have different expiry rules.

Can I use the same eSIM on several family phones?

Most travel eSIM profiles are tied to one compatible device and are not generally transferable without the provider’s support. Each phone may need a separate plan, or travellers may share data via permitted hotspot limits.

NextNews verdict: the best Asia eSIM depends on your itinerary

For fixed-data trips through multiple Asian countries, Airalo is a strong value starting point at the checked 10 GB price. For longer and Asia–Oceania itineraries, Saily’s wider country list and 60-day package warrant consideration. Ubigi is useful when hotspot sharing and visible local network partners matter. Holafly may appeal to heavy phone-data users, but its speed policy and daily tethering cap should be weighed carefully.

There is no substitute for checking the exact countries, local networks, total payment, device compatibility and plan rules immediately before buying. An eSIM is a travel convenience—not a guarantee of full signal in every mountain village, island or rural district.

Best eSIM for Australians Travelling to Asia in 2026: Airalo vs Saily vs Ubigi vs Holafly
