You’ve probably seen the same three names pop up every time you search for a travel eSIM: Airalo, Holafly, and Travelren. They all work. They all make different trade-offs. And the marketing from all three insists they’re the cheapest and fastest, which can’t all be true at once.
This is a straight comparison for American travelers: real USD pricing, which carriers each brand uses in the countries you’re most likely to fly to, and when each option actually makes sense. We’ll use Opensignal’s public network data rather than our own claims, and we’ll list our own prices alongside competitors so you can draw your own conclusions.
Travelren owns the margin spreadsheet that compares us to our competitors. Our team would rather tell you when Airalo or Holafly is the better fit for your trip than oversell you on us, because the alternative — you buying the wrong eSIM and never coming back — costs more in the long run.
The quick answer, before you scroll
Short version: for a week in Tokyo using roughly 5GB, you’ll spend around $8 with Travelren, $8.50 with Airalo, or $37 with Holafly for ten days of unlimited. For a week in Bangkok: around $6 with Travelren, $6.50 with Airalo, and $22 with Holafly. For a week in Mexico: roughly $7 with Travelren, $8 with Airalo, and $37 with Holafly unlimited.
Travelren and Airalo are close to price parity on most destinations. Holafly runs 3 to 4 times more expensive because they only sell unlimited plans. The real differences show up in data structure, support quality, and what happens when something doesn’t work — not in the headline price.

How we actually compared them
We pulled the current public price for a comparable plan on each provider in April 2026 — around 3GB over 30 days, or the unlimited equivalent for Holafly. Prices are retail, not first-time-buyer-discounted, since those codes expire and you can’t count on them for your next trip.
Carrier routing comes from Airalo’s network disclosures, Holafly’s public plan pages, and our own supply partner confirmations. Network performance data comes from Opensignal’s country mobile network experience reports — free, methodical, the industry benchmark for measured rather than advertised speeds.
Japan: the bucket list trip
Japan is the highest-volume eSIM search from US IPs after Mexico. Here’s the breakdown on a typical plan size.
Japan — 3GB over 30 days
- Travelren: $8, routes on SoftBank and KDDI 5G
- Airalo “Moshi Moshi”: approximately $8.50, routes on SoftBank and KDDI
- Holafly: no 3GB option — their smallest is 10 days unlimited at around $37
Opensignal’s April 2025 Japan Mobile Network Experience report awarded NTT Docomo the 5G download speed crown at 168 Mbps, with SoftBank winning on 5G availability. For most visitors in Tokyo, Osaka, or Kyoto, you’ll pull above 100 Mbps on either SoftBank or Docomo — the practical difference is zero. The gap matters more for rural Hokkaido or the Japanese Alps, where NTT Docomo’s deeper infrastructure wins. No consumer eSIM brand routes on Docomo-primary, so if you’re doing serious rural Japan travel, plan around that limitation.
The honest recommendation for Americans: AT&T’s International Day Pass is $12/day for Japan, meaning a 7-day trip costs $84 in roaming. That’s 10x any of the eSIM options. Skip roaming entirely. For urban Japan trips, Travelren and Airalo are interchangeable — pick whichever app you prefer. For heavy data users on longer trips, Holafly’s 10-day unlimited at $37 stops looking crazy. See the full Travelren Japan plan range from 1GB through 20GB.
Mexico: the easy weekend trip
Mexico is the single biggest outbound destination for US travelers by volume. The eSIM math here is weirder than you’d think because T-Mobile customers already get free data in Mexico and Canada on most plans. If you’re on T-Mobile Magenta or Go5G, you may not need any eSIM at all — check your plan before you buy.
Mexico — 3GB over 30 days
- Travelren: approximately $7, routes on Telcel
- Airalo “Tec Mexico”: approximately $8, routes on Telcel and AT&T Mexico
- Holafly: 10 days unlimited at around $37
Telcel has the broadest Mexico coverage including most of Yucatán, Baja California, and the Pacific coast resort strip. AT&T Mexico is strong in northern states and major cities but thinner in rural and resort areas. Opensignal’s Mexico reports put Telcel comfortably ahead on 4G availability and rural reach.
The honest recommendation: T-Mobile customers should check their plan first — international data in Mexico may already be included. Verizon and AT&T customers pay $12/day on International Day Pass, making even a 4-day trip to Cancun cheaper on eSIM. Travelren and Airalo are close on price with Telcel primary on both.
Thailand: the longer trip
Thailand is the cheapest country across every eSIM provider and the destination where data-capped plans genuinely shine.
Thailand — 3GB over 30 days
- Travelren: $6, routes on AIS 5G
- Airalo “Vapor”: approximately $6.50, routes on AIS and True Corp
- Holafly: 10 days unlimited at around $22
AIS dominates Thailand network rankings on Opensignal’s Thailand reports — leading 5G availability, leading rural reach, and strong in the tourist regions of Phuket, Krabi, and Koh Samui. True Corp is competitive in Bangkok but loses ground outside the capital. Both Travelren and Airalo route AIS-primary, which means network experience is effectively identical.
The honest recommendation: AT&T Day Pass is $12/day to Thailand — a 14-day trip costs $168 in pure roaming. For any Thailand trip over three days, an eSIM is dramatically cheaper. Travelren is marginally cheaper than Airalo at every tier. Holafly is only worth it for true digital nomad use (30+ days, heavy daily data).
Europe: where regional plans win
Most US travelers heading to Europe visit multiple countries — London plus Paris plus Rome, or the full Mediterranean loop. For those trips, a country-by-country eSIM is a bad idea. Regional plans change the math entirely.
Europe regional — 5GB over 30 days, 25+ country coverage
- Travelren regional: approximately $16
- Airalo “Eurolink”: approximately $14, category leader for multi-country Europe
- Holafly regional Europe: 10 days unlimited at approximately $34
Regional plans route across each country’s partner carriers — Vodafone in Germany, Orange in France, TIM in Italy, EE in the UK, Movistar in Spain. Opensignal ranks Vodafone and Orange highly for 5G in their respective countries, and regional plans generally inherit that performance.
The honest recommendation: Airalo’s Eurolink is the category leader for multi-country Europe and the one we’d recommend over our own regional plan. Travelren is competitive on country-specific plans (UK-only, Italy-only); Airalo has scale advantages on regional roaming agreements that we haven’t matched yet.
UK specifically
UK — 3GB over 30 days
- Travelren: $9, routes on EE 5G
- Airalo “Uki”: approximately $8, routes on EE and Three
- Holafly: 10 days unlimited at around $37
Airalo has a slight price edge on UK-only plans. Network experience is identical — both route EE primary, and EE leads Opensignal’s UK 5G rankings consistently. If your trip is London and a day trip to Edinburgh, Airalo wins by a dollar. If you’re adding Paris, switch to Eurolink regional.
What matters beyond the headline price
Prices change. Today’s $2 advantage can vanish in a month when a provider runs a promotion. The durable differences are structural.
Fixed data vs unlimited
Travelren and Airalo sell fixed-data plans. You buy 3GB, 10GB, or 20GB and that’s your budget. If you run out, top up or finish the trip on WiFi. Holafly only sells unlimited — pay more upfront, don’t think about data. For content creators, remote workers, and anyone navigating with 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” throttles above roughly 90GB per month and caps hotspot tethering at 500MB per day. Before you assume unlimited means tethering a laptop for a week of remote work, read the fine print.
Customer support
Hard to benchmark fairly when we run one of the three companies, so we’ll report what forum consensus says. Holafly’s 24/7 WhatsApp support is the strongest of the three for real-time issues — they deliver on it. Airalo has in-app chat with response times that vary by time zone. Travelren answers email within US business hours (we’re based in Sydney, so morning US = evening AU and vice versa, which works out well for turnaround). For complex activation issues Holafly wins. For simple questions any of them are fine.
What happens when the primary network drops
All three brands let your phone pick the strongest signal from partner networks automatically. You can’t manually switch. If the primary network has an outage in your area, all three fail identically. Your home SIM staying active as a secondary line for calls and SMS is the real insurance, not the eSIM brand you choose.
A clear recommendation matrix for Americans
- First-time travel eSIM, short trip to Asia or Mexico: Travelren or Airalo. Flip a coin — prices are within a dollar and carriers are the same.
- Multi-country Europe trip: Airalo Eurolink. Category leader, honestly better than what we offer.
- Month-long trip, heavy data use, hate topping up: Holafly. Pricier but the only one that makes unlimited practical.
- Mexico short trip and you’re on T-Mobile: check your plan first. You may not need an eSIM at all.
- Thailand or Japan trip longer than a week: skip AT&T/Verizon Day Pass ($12/day) — eSIM is roughly 90% cheaper.
- Long stay, heavy data, value per GB above all else: buy a physical local SIM on arrival. Cheaper per GB but costs time and sometimes passport registration. Only worth it beyond three weeks.
What we’re not trying to change your mind about
If you’ve used Airalo four times and their app is muscle memory, a $1 price difference isn’t worth the switching cost. If Holafly burned you once, trust that. If Travelren is new to you, test us on a short trip before committing to a big one. That’s sensible behavior.
What we do want you to do: pick one, install it before you fly, and test it works on your phone at home before you’re fighting airport WiFi. All three brands support installation days or weeks before activation. Don’t leave it to the jetway.
Before anything: confirm your phone supports eSIM
Every comparison assumes your phone can run an eSIM. Most iPhones from the XS onwards (US models are all eSIM-only since iPhone 14), every recent Google Pixel, and most flagship Samsung Galaxy devices work. The main exception is iPhones originally sold in mainland China, which lack the eSIM hardware even though the model number looks identical to a US unit. If you’re unsure, our device check tool confirms in 30 seconds, works for every eSIM brand.
Frequently asked questions
Is Travelren cheaper than Airalo for US travelers?
On most destinations Travelren and Airalo are within a dollar of each other in USD. Travelren is meaningfully cheaper on US-domestic plans (about 20% below Airalo for travelers visiting the US from abroad) and on Mexico plans. Airalo edges Travelren by about $1 on UK-only and Eurolink regional. For Japan, Thailand, and most other destinations, the prices are close enough that interface preference matters more than the headline.
Is an eSIM cheaper than AT&T or Verizon International Day Pass?
Almost always yes. AT&T’s International Day Pass is $12/day in most countries; Verizon’s TravelPass is $10/day. A 7-day trip costs $70–84 in roaming. The same week on a Travelren or Airalo eSIM costs $6–14 total. The exception is T-Mobile’s free Mexico/Canada data on Magenta and Go5G plans — if you’re on those, you don’t need an eSIM for trans-border trips.
Will an Airalo, Holafly, or Travelren eSIM work on my US iPhone?
Yes — every iPhone sold in the US from the iPhone 14 onwards is eSIM-only and supports any travel eSIM brand. iPhone XS through 13 also support eSIM but allow physical SIM swaps too. The exception is iPhones originally bought in mainland China, which lack the eSIM hardware. Our device check tool confirms in 30 seconds.
Can I keep my regular phone number active while using a travel eSIM?
Yes — that’s the whole point of dual-SIM. Keep your US number active for calls and SMS (banks, two-factor auth, family contact) and route data through the travel eSIM. Turn data roaming off on your home line in Settings before you fly so you don’t accidentally rack up charges.
What happens if my eSIM data runs out mid-trip?
Top up from inside the brand’s app — usually under a minute, the new allowance activates 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 advice was “figure it out when you land.” Today Travelren, Airalo, and Holafly all ship products that work reliably from the jet bridge onward. The decision isn’t whether to use an eSIM — it’s which one fits your trip.
For most Americans on most trips, Travelren and Airalo are close to indistinguishable on price and carrier routing. Holafly is the premium option: pay more, worry less. Physical local SIMs stay the cheapest per GB but cost time and flexibility. AT&T and Verizon International Day Passes at $12 are categorically worse than any eSIM option for trips longer than a few days — the only exception is very short trips where the simplicity of not installing anything wins.
Whichever you pick, install it at home, keep your home SIM active as a secondary line, and verify your phone supports eSIM before assuming it does. That’s the 90% that matters.
