If you’ve searched for a travel eSIM lately you’ll have seen the same three names: Airalo, Holafly, and Travelren. Each one works. Each one has genuine trade-offs. The marketing on all three tells you they’re the cheapest and the fastest. None of that is entirely true.
This is an honest breakdown for Australian travellers: what each brand actually costs in Australian dollars, which carriers they route through in the countries you’re likely to visit, and which situations each one fits best. We’ll lean on Opensignal data rather than our own marketing claims, and we’ll list prices for our own plans alongside the competition so you can make the call yourself.
Travelren owns the margin spreadsheet that compares us to our competitors, and our team would rather tell you when a competitor is the right choice for your trip than pretend we win every comparison. The cost of you buying the wrong eSIM and never coming back is higher than the cost of losing today’s sale.
The quick answer, before you scroll
Short version: for a week in Tokyo with 5GB of usage you’ll spend around AUD$12 with Travelren, AUD$13 with Airalo, or AUD$40 with Holafly. For the same week in Bangkok, roughly AUD$9 with Travelren, AUD$9.50 with Airalo, and AUD$40 with Holafly. For a week in the USA: around AUD$14 with Travelren, AUD$18 with Airalo, and AUD$40 with Holafly.
Travelren and Airalo are roughly at parity on price across most destinations. Holafly is consistently 3 to 4 times more expensive because they only sell unlimited plans and price them as a premium product. The real differences between the three come down to carriers, data structure, and what happens when something goes wrong.

How we actually compared them
We pulled the current public price for the middle-of-the-road plan on each provider in April 2026 — something close to 3GB over 30 days, or the unlimited equivalent for Holafly since they don’t sell data-capped plans. USD converted to AUD at 1.52. Prices are retail, not discount-code adjusted, because those discounts are often first-time-only and you can’t count on them for a repeat purchase.
Carrier data comes from Airalo’s own network disclosures, Holafly’s plan pages, and our own supply partner confirmations. Network speed figures come from Opensignal’s country experience reports published in 2025, which are free, public, and the industry benchmark for measured (not advertised) performance.
Japan: the trip most Australians are planning
Japan is the single biggest eSIM search from Australian IP addresses. Here’s how the three brands stack up on the most common plan size.
Japan — 3GB over 30 days
- Travelren: AUD$12 (USD$8), routes on SoftBank and KDDI 5G
- Airalo “Moshi Moshi”: approximately AUD$13 (USD$8.50), routes on SoftBank and KDDI
- Holafly: doesn’t sell a 3GB plan. Their closest offer is unlimited over 10 days at around AUD$56 (USD$36.90)
On Opensignal’s April 2025 Japan Mobile Network Experience report, NTT Docomo took the 5G download speed award at 168 Mbps, with SoftBank just behind on 5G availability. Practically, the difference between SoftBank and NTT Docomo on your phone in Tokyo is invisible: you’ll pull above 100 Mbps in Shibuya either way. The more relevant question is rural coverage, and there the picture shifts slightly — NTT Docomo has the strongest mountain and remote-prefecture coverage, SoftBank is slightly weaker outside major cities.
Why this matters: both Travelren and Airalo route through SoftBank primarily. If your trip is Tokyo, Osaka, Kyoto, Hiroshima, and Fukuoka — the standard first-time Japan circuit — it won’t matter which you pick. If you’re going deep into Hokkaido, the Japan Alps, or rural Tohoku, no consumer eSIM brand routes on NTT Docomo as the primary. You’d need a physical local SIM from a carrier shop in country to get Docomo-primary coverage, and that’s rarely worth the hassle for a two-week trip.
The honest recommendation: for a first Japan trip focused on cities, Travelren and Airalo are interchangeable on price and performance. Pick whichever has the interface you prefer. If you’re a power user who burns 10+ GB per week on video calls and navigation, Holafly’s unlimited plans become defensible at around AUD$56 for ten days — painful on price, but you don’t have to top up.

Thailand: the second most common destination
Thailand is the second biggest destination searched by Australian travellers, and the cheapest country for eSIMs across every provider.
Thailand — 3GB over 30 days
- Travelren: AUD$9 (USD$6), routes on AIS 5G
- Airalo “Vapor”: approximately AUD$9.50 (USD$6.50), routes on AIS and True Corp
- Holafly: 10 days unlimited at around AUD$34 (USD$22)
The Thailand comparison has one genuine differentiator that matters: Telstra’s International Day Pass to Thailand is AUD$2.50 per day for 2GB of data, making it one of the cheapest roaming destinations from Australia. For a short trip — say three or four days in Bangkok — Telstra roaming at AUD$10 all-in is within a couple of dollars of any eSIM option. For a two-week Thailand trip that number becomes AUD$35 and the eSIM advantage grows meaningfully.
AIS is the dominant network on both Travelren and Airalo’s Thai eSIMs. Opensignal’s Thailand reports consistently show AIS leading on 5G availability and rural coverage, with True Corp strong in Bangkok and the tourist islands but weaker in Isaan and the far north. If your itinerary is Bangkok, Phuket, Krabi, or Koh Samui, either provider will give you near-identical network experience. If you’re heading to Pai, Chiang Rai, or Koh Kood, AIS as the primary routing is a quiet advantage.
The honest recommendation: for trips under four days to Bangkok only, roaming on Telstra is almost price-matched and genuinely simpler — no QR scanning, your number stays live. For anything over four days or travel outside the capital, Travelren or Airalo saves meaningful money. Holafly is overpriced for Thailand unless you’re there for a month and want zero data anxiety.
USA: the expensive destination
The United States is where eSIM economics pull clear of roaming. Telstra’s Day Pass jumps to AUD$10 per day in the US (Zone 2), which means a two-week trip costs AUD$140 just in roaming fees on your home number — before you buy any local plan at all.
USA — 3GB over 30 days
- Travelren: AUD$14 (USD$9), routes on T-Mobile and Verizon 5G
- Airalo “Change”: approximately AUD$18 (USD$12), routes on T-Mobile and Verizon
- Holafly: 10 days unlimited at around AUD$56 (USD$36.90)
This is the only destination in this comparison where Travelren is meaningfully cheaper than Airalo on the retail rate — about 20% below. Holafly remains the premium option at roughly 4x the fixed-plan price.
T-Mobile is the primary carrier on both Travelren and Airalo’s US plans. Opensignal’s United States reports have consistently placed T-Mobile first for 5G availability and rural reach since 2023 thanks to their low-band 5G deployment, though Verizon edges them on peak speed in dense urban zones. For most Australian travellers — who are flying into LAX, JFK, or SFO and doing the standard national park road trip — T-Mobile primary is a genuine plus.
The honest recommendation: for any US trip longer than three days, skip roaming entirely. Travelren is the cheaper of the two fixed-plan options. Holafly makes sense if you need true unlimited data for a month-long trip and don’t want to think about top-ups. Avoid physical carrier SIMs at US airports — they’re usually locked to a specific carrier’s in-store plan and require a US billing address to activate online.
UK and Europe: where the comparison gets interesting
The UK is a simpler story. EE is the dominant carrier on both Travelren and Airalo’s UK plans. Prices are close:
UK — 3GB over 30 days
- Travelren: AUD$14 (USD$9), routes on EE 5G
- Airalo: approximately AUD$12 (USD$8), routes on EE and Three
- Holafly: 10 days unlimited at around AUD$56
Airalo has a slight price edge on UK plans. The network experience is effectively identical. What shifts the math for most Australian travellers is that if you’re doing the UK-Europe loop — London, Paris, Rome, Amsterdam — you likely want a regional eSIM rather than a UK-only plan. That’s a different comparison worth a separate article, but the short version: regional Europe plans from all three providers average around AUD$22 to AUD$25 for 5GB across 25+ countries, and Airalo’s “Eurolink” is the category leader.
The honest recommendation: if your trip is UK-only, any of the three works. If it’s UK plus multi-country Europe, Airalo’s Eurolink regional plan is the smart pick for most travellers.
What actually matters beyond the headline price
Prices move. Today’s 10% advantage can flip in a month when a provider runs a sale. The durable differences between Travelren, Airalo, and Holafly are structural.
Data caps vs unlimited
Travelren and Airalo both sell fixed-data plans. You buy 3GB or 10GB and that’s your budget. Run out, top up, or burn through the rest of your trip on WiFi. Holafly sells unlimited only — you pay more upfront but never think about data again. For content creators, remote workers, and anyone using Google Maps all day while also video-calling home, Holafly’s model removes a small but real source of trip anxiety.
The catch: Holafly’s “unlimited” has a throttle above roughly 90GB per month and a 500MB daily hotspot cap. Read the fine print before you assume it means tethering your laptop for Zoom calls all week.
Customer support
This is hard to measure fairly from inside one of the three companies, so we’ll report what the forum consensus says. Airalo has in-app chat with variable response times depending on time zone. Holafly pushes their 24/7 WhatsApp support heavily and generally delivers on it. Travelren responds via email — we’re small enough that support emails hit a real person on the same day in Sydney business hours. For complex activation issues Holafly’s real-time chat is the strongest of the three; for most simple questions any of them are fine.
Network changes mid-trip
None of the three brands let you manually switch carriers within a plan — your phone picks the strongest signal from the available partner networks. This is actually how it should work, but it means if the primary network has an outage in your area, all three options fail the same way. Your home SIM staying active in the background (as a secondary line for calls and SMS) is the best insurance, not the brand you choose.
A clear recommendation matrix
For the Australian traveller reading this, here’s how to pick:
- First time using a travel eSIM, short trip to Asia: Travelren or Airalo. Flip a coin. The prices are within a couple of dollars and the carriers are the same.
- US trip longer than a week: Travelren. Price advantage is real at around 20% cheaper than Airalo, and T-Mobile primary is solid for national park road trips.
- Multi-country Europe loop: Airalo Eurolink. Category leader for regional plans.
- Month-long trip, heavy data use, hate topping up: Holafly. Priciest but the only one that makes unlimited viable.
- Trip under 4 days to Thailand or UK: Telstra International Day Pass at AUD$2.50 or AUD$5 respectively might be cheaper and simpler. Do the math on your exact itinerary.
- Power user who wants the single best network in every country: buy a physical local SIM on arrival. Cheaper per GB, but costs time and sometimes passport registration. Worth it only for stays longer than three weeks.
What we’re not going to try to change your mind about
If you’ve already used Airalo three times and the app is muscle memory, don’t let a 5% price difference lure you away. The time cost of learning a new buying flow and re-entering payment details on your phone probably exceeds the saving. If you’ve had a bad experience with Holafly, trust it. If Travelren is new to you and you want to test us on a short trip before committing to a big one, that’s the sensible approach.
What we do want you to do: pick one, install it before you fly, and check it works at home before you’re rushing through airport WiFi. All three brands support installation days or weeks before activation. Don’t leave it to the jetway.
Before anything: check your phone supports eSIM
Every comparison above assumes your phone can run an eSIM. Most iPhones from the XS onwards, every recent Google Pixel, and most flagship Samsung models work. iPhones bought in mainland China are the main exception — they don’t have the eSIM hardware even when the model number looks identical to an Australian-sold unit. If you’re unsure, our device check tool tells you in 30 seconds. Free and works for every eSIM brand, not just ours.
Frequently asked questions
Is Travelren cheaper than Airalo for Australians?
On most destinations Travelren and Airalo are within a dollar or two of each other in AUD. The exception is the USA, where Travelren is about 20% cheaper at retail. For Japan, Thailand, and the UK the prices are close enough that interface preference and existing accounts matter more than the headline number.
Will an Airalo, Holafly, or Travelren eSIM work on my Australian iPhone?
Almost certainly yes. Every iPhone from XS (2018) onwards sold in Australia supports eSIM. The exception is iPhones originally bought in mainland China, which lack the eSIM hardware even when the model number matches. Our device check tool confirms in 30 seconds — works for any eSIM brand, not just ours.
Should I use Telstra Day Pass roaming or buy an eSIM?
For trips under three days to Zone 1 countries (Thailand, Indonesia, NZ) where Telstra Day Pass costs AUD$2.50/day, roaming is price-competitive and simpler — your number stays live. For trips over four days or to Zone 2 countries (USA, Europe, Japan) where Day Pass is AUD$5–10/day, an eSIM is dramatically cheaper. Run the math on your exact itinerary.
Can I use my home SIM at the same time as a travel eSIM?
Yes — that’s the whole point of dual-SIM phones. Keep your Australian number active for calls and SMS (banks, two-factor auth, family contact) and route data through the travel eSIM. You won’t pay roaming on the home SIM as long as you turn its data off, which you do once in iPhone or Android settings before you fly.
What happens if my eSIM data runs out mid-trip?
You can top up from inside the brand’s app — usually takes under a minute and the new allowance becomes active immediately. Travelren, Airalo, and Holafly all support in-app top-ups. The trade-off with fixed-data plans (Travelren and Airalo) is you have to remember to do it; Holafly’s unlimited plans skip this entirely but cost 3–4x more upfront.
The final take
Travel eSIMs have matured fast. Five years ago the honest recommendation was “figure it out when you land”. Today all three of Travelren, Airalo, and Holafly ship a product that works reliably from the jet bridge onward. The choice is no longer whether to use an eSIM — it’s which one fits your specific trip.
Price parity between Travelren and Airalo on most plans means the decision for most Australian travellers is closer to a preference call than an economic one. Holafly is the premium option: pay more, worry less, don’t think about data. Physical local SIMs remain the cheapest per GB but cost time and flexibility. Telstra roaming is the honest winner for very short trips to low-zone countries.
Whichever one you pick, install it at home, keep your home SIM active as a secondary line, and check your device supports eSIM before you assume it does. That’s 90% of what matters.
