Saily’s Unlimited plan gives you 5 GB a day at full 4G/5G speed, then keeps you online at 1 Mbps for the rest of the day. Saily sells plans per country, per region and as one global plan, by the gigabyte, unlimited or both, while Maya’s one Global plan covers 165+ countries with unlimited data, priced flat by trip length from USD 9.99 for 3 days.
Nothing wrecks a landing like data that crawls by lunch, so read the allowance before you pay.
What does a Saily eSIM plan include for a trip?
A Saily plan is a travel data eSIM sold per country, per region or as one global plan, by the gigabyte, unlimited, or both. Saily says mobile data is available in more than 200 countries and regions, and that phone calls and SMS are available in fewer (Saily Help Center).
Beyond data, Saily says every plan includes a virtual location, an ad blocker and web protection at no extra cost. Its app offers 115+ virtual locations, and Saily says the security features need nothing extra to download or configure: you open the app and tap to enable them (Saily). If you hit a connection issue, Saily’s published line is that its support team is available 24/7.
So you’re buying a data plan with a security bundle on top. Calls and texts are a separate matter, and coverage for them is narrower than for data.
How much full-speed data does Saily’s Unlimited plan give each day?
Saily’s published Unlimited plan gives you 5 GB per day at full 4G/5G speed. After that you stay online at 1 Mbps for the rest of the day, which Saily describes as fast enough for navigation, messaging and standard browsing.
The 5 GB is not the same everywhere. Saily’s terms say the full-speed allocation on a regular Unlimited plan is either 3 GB or 5 GB depending on the destination. It resets at local midnight in your current time zone, so crossing a time zone does not hand you a second allowance.
Saily also sells Saily Ultra, which its own page describes as 30 GB of super-fast data each month, with unlimited data at 1 Mbps after that. Ultra renews automatically every month. Saily’s pages list hotspot sharing as unlimited on its Europe and Mexico plans.
What is Saily’s refund policy for an eSIM plan?
Saily refunds a plan you never used. Its published terms say that if the eSIM has not been installed, or is installed but the data plan is not activated, you may request a full refund, provided no Extras included with the plan have been used, reserved or shared.
An activated plan is tougher. Saily’s terms set a second route for a non-subscription plan that was activated but left generally unused, with more than 99% of the balance remaining, and any complimentary Extras must also be untouched. Once you’ve used real data, you’re outside both routes.
That makes the install-to-activation gap the part to watch. Saily’s UK page says you can install and activate the eSIM within 180 days of purchase, and an unactivated plan then activates automatically (Saily Help Center).
How much does a Saily eSIM cost compared with roaming?
A major home carrier’s roaming day pass costs $12 per day: Verizon’s TravelPass is $12 per line per day plus taxes and fees, and AT&T’s International Day Pass is $12 a day.
For a concrete Saily unlimited price, GBScout’s 2026 comparison of 48 destinations lists a Saily 7-day unlimited plan for Canada at $28.99 (GBScout, 2026). A day pass bills by the day, per line. A Saily plan is bought once for a set number of days.
Saily’s starting prices are for its smallest, shortest plans. Its single-country plans run from 1 GB up to Unlimited, so the price you pay moves with the size and length you pick.
Which travelers suit a Saily plan, and who needs something else?
A Saily plan suits a traveler who wants data sized to one trip. Its UK page lists plans from 1 GB to Unlimited, lasting 3, 5, 7, 10, 15, 20, 25 or 30 days (Saily).
It also suits someone who wants the security extras or hotspot sharing, which Saily’s pages list as unlimited on several plans. Travelers who need calls and texts should check the country first, because Saily says voice and SMS cover fewer countries than data.
When something breaks, the experience gets rougher. Jon M. gave Saily one star on Trustpilot on June 12, 2026: “I would strongly advise against using Saily. Worked great to begin with. My eSIM stopped working and was ultimately deleted from my phone. Since then, I’ve spent hours following every troubleshooting step requested by support: reinstalling the app, checking settings, restarting the device, and itt rrepeatedly providing the same information. The problem is that Saily’s system still shows the eSIM as “installed,” while the eSIM no longer exists on my phone. Rather than simply reissuing or reinstating the eSIM, support has continued to send me through the same troubleshooting loop. To make matters worse, despite being unable to provide a working service or reinstate the eSIM, they have refused to provide a refund because some data had previously been used. I paid for a service that I can no longer access, and their solution appears to be endless troubleshooting rather than actually fixing the issue. Customer support responses are polite, but the process feels completely circular. After doing everything requested, I am no closer to having a working eSIM than when I started. Based on this experience, I cannot recommend Saily. When things work, they’re fine. When something goes wrong, getting a resolution seems unnecessarily difficult and when talking a real person it just feels like another bot. It is a real shame as so many people review this company very highly and I am a big fan of NordVPN.”
Trips that cross borders raise another question: how many plans you end up buying.
What Saily, Airalo, Holafly and Nomad say their unlimited data includes
Each of the four sets a different daily rule. Saily gives 5 GB at full speed, then 1 Mbps. Airalo says that when you use more than 3GB in a day, it throttles your speed to 1 Mbps for the rest of that day (Airalo, 2026).
Airalo adds that your full high-speed connection is restored when your daily allowance resets, every 24 hours counted from the time you activated your eSIM (Airalo, 2026). Nomad lets you pick how many GB of high-speed data you want per day, and says you can keep using data at a throttled 512kbps after you’ve used your daily allocation.
Holafly words it differently. It offers unlimited data plans for over 200 destinations, from 1 to 90 days, and says a local operator’s Fair Usage Policy may temporarily reduce your speed for no more than one day (Holafly FAQs, 2026). Its terms also say that Holafly or the network provider may restrict data usage or speed if your use is deemed excessive (Holafly Terms and Conditions, 2026).
Four companies say “unlimited”, and each one means something a little different.
How Maya turns every trip into one flat plan
Maya sells one eSIM that you install once and keep on your phone. Each trip is a plan priced flat by length, 3, 7, 14 or 30 days, from USD 9.99, with unlimited data and a daily high-speed allowance across 165+ countries. The next trip is a new plan from the app.
No SIM swaps. No hunting for a plan per country. One plan covers multi-country travel, so adding a country on the same trip keeps one plan and one eSIM, and a longer trip is one more plan on that eSIM. Atlas, our small globe with a massive passport, takes lost luggage in stride, and a plan menu per border is a different story.
The daily high-speed allowance is what Maya calls the Daily Quota. It runs at up to 4G LTE or 5G where local networks offer it, resets every 24 hours, and then unlimited data continues at standard speed. Waseem S. gave Maya five stars on Trustpilot on September 29, 2026: “I used their eSIM during my recent trip to USA, and it was absolutely perfect. The data worked seamlessly the entire time. What really stood out was their customer support; they were incredibly helpful and quick to resolve a couple of initial questions I had. Highly recommended for any traveler!”
Saily, Airalo, Holafly, Nomad or Maya: which unlimited plan terms fit your trip?
The decision comes down to three things: how the plan is sold, what the daily allowance does after you pass it, and what happens if the eSIM never works. Each company’s published words are below.
| Travel eSIM | How plans are sold | Unlimited plan allowance, as published | Refund terms, as published |
|---|---|---|---|
| Maya Mobile | One Global eSIM for 165+ countries, unlimited data at a flat price by trip length: USD 9.99 for 3 days, USD 19.99 for 7 days, USD 27.99 for 14 days, USD 49.99 for 30 days | A daily high-speed data allowance (the Daily Quota) at up to 4G LTE or 5G where local networks offer it, reset every 24 hours; unlimited data at standard speed once the Daily Quota is used | A money-back guarantee when the eSIM cannot be installed or used, on the conditions in the return policy |
| Airalo | Per country, per region, or one global plan; priced in USD | Our unlimited data packages don’t have a fixed total data cap. However, to keep the network running fairly for everyone, when you use more than 3GB in a day, we’ll slow down (or “throttle”) your internet speed to 1 Mbps for the rest of that day. | Replacements and Refunds. If you have activated the Services but are unable to use them due to an error or omission on the part of Airalo, or because Airalo has decided to retire the Service, we will either provide a replacement Service or refund an amount equal to the price of the Service you have purchased in full, at your option. |
| Holafly | Per country, per region (Europe, Latin America, Cruise plans), and unlimited monthly/annual global plans | Unlimited data means there is no fixed limit on the amount of data you can use. However, some network operators may temporarily reduce your speed after a certain amount of high-speed data usage, as explained above. | Purchase your Holafly eSIM with added peace of mind. You have up to 6 months to request a refund. |
| Saily | Per country and per region, plus one global plan; by the gigabyte, unlimited, or both | The Unlimited plan gives you 5 GB per day at full 4G/5G speed, then keeps you online at 1 Mbps for the rest of the day — fast enough for navigation, messaging, and standard browsing. | Refunds for Non-Activated Data Plans. If the eSIM (i) has not been installed or (ii) has been installed on your device but the Data Plan is not activated, you may request a full refund, provided that no Extra(s) included with the Data Plan have been used, reserved or shared, in whole or in part. |
| Nomad | Per country, per region and global plans; by the gigabyte | How many GB of high-speed data you wish per day. You can continue to use your data at a throttled speed of 512kbps after you’ve used up your daily allocation. | Learn Nomad eSIM’s refund policy: request within 30 days. Full refunds if unused; partial refunds may apply for unused data or service issues. |
In the table, the Airalo, Holafly, Saily and Nomad cells carry each company’s own wording or a brief summary of it, while the Maya Mobile cells carry Maya’s own terms.
Maya Mobile: one eSIM, one flat price for your whole trip
Pick your days and go. Maya Mobile is a travel eSIM giving unlimited data in 165+ countries and 20+ cruise lines through a single eSIM permanently installed on your phone. It stays on the phone, so every trip after the first is just a new plan.
Each Maya plan is bought once and finishes when its days run out. Auto Top-Up is opt-in and off by default, and you can turn it off any time from My eSIM in the app or at maya.net. If the eSIM can’t be installed or used, our money-back guarantee applies on the conditions in our return policy.
Martin L. gave Maya five stars on Trustpilot on January 16, 2026: “My go to for an esim whilst travelling! Very easy set up and really good value for money too!”
FAQ
Which phones can use a travel eSIM?
Any phone that is unlocked, eSIM-capable and compatible with the network. Cricket Wireless puts the requirement as an unlocked, eSIM-capable, network-compatible device. For Maya, the phone must be carrier-unlocked. Run your model through the compatibility checker at maya.net/esim-compatible-devices before you buy.
What is the difference between a daily high-speed allowance and truly unlimited data?
It is the speed you get once the fast data is gone, because you stay online either way. Saily and Airalo publish a figure for that slower speed. With Maya, the Daily Quota resets every 24 hours and unused quota does not carry over. After that, unlimited data continues at standard speed, which depends on local network conditions, and no speed is guaranteed.
What happens to a Saily plan when its days or data run out?
You top up in the Saily app. Open the app, select your eSIM, choose add data, pick the location and plan size, then pay. On an Unlimited plan, your speed drops to about 1 Mbps for the rest of the day once you use the daily high-speed allowance (Saily Help Center).
Does a travel eSIM cover cruise ships?
Yes, with Maya’s Global + Cruise plan, bought separately from the Global plan. It covers 20+ cruise lines and 165+ countries, and is priced on its own: USD 49.99 for 3 days, USD 109.99 for 7 days and USD 299.99 for 30 days. At sea, connectivity runs over satellite and maritime networks, so it depends on the vessel and route. Speeds may differ from land, and coverage in any specific place can vary for reasons outside our control.
Will a travel eSIM renew and charge me again on its own?
No. Each Maya plan is a one-time purchase that ends when its days end, unless you turn on Auto Top-Up. Auto Top-Up buys the same plan again when the current one expires, and your card is charged only while it’s on. Turn it off any time from My eSIM; a plan period already begun is not refunded. Saily’s regular plans also don’t renew unless auto top-up is enabled, while Saily Ultra renews monthly.
Maya is one travel eSIM with unlimited data in 165+ countries, priced flat by trip length from USD 9.99 and installed once on your phone.
