Airalo vs Holafly: Data Limits, Prices and Which Fits Your Trip

Airalo and Holafly are the two names that come up most often when travelers compare eSIMs, and they represent two different ways of selling mobile data. Airalo's catalogue is built around packages you choose by gigabytes and days, with unlimited options added for some destinations. Holafly sells unlimited data only, priced by the number of days. The right choice depends less on brand loyalty than on how many days you travel, how much data you burn per day, and whether other devices depend on your phone.

The two models in one table

Both companies publish these terms on their own pages, and both change them from time to time. Treat this table as a map of the structure rather than a permanent record.

Step 1: estimate your daily data honestly

The whole comparison collapses to one number: gigabytes per day. Your phone already knows it. On iPhone, Settings, Mobile Service shows usage per line; on Android, Settings, Network and internet, SIMs shows app-level totals. Divide last month's total by 30 and you have a realistic baseline for a trip, then adjust:

• Maps, messaging, email and browsing rarely exceed a few hundred megabytes a day.

• Social video, music streaming and photo backup push the figure well above a gigabyte.

• Tethering a laptop or a partner's phone can double or triple it.

Airalo's own help page underlines why this matters for fixed plans: the data is for the entire validity period, so a light user can carry unused gigabytes into later days, while a heavy user can empty a package in a weekend.

Step 2: calculate cost per gigabyte for your trip length

Prices differ by destination and move often, so the useful thing to carry away is the method rather than a fixed verdict. For a fixed-data plan, cost per gigabyte is the package price divided by the gigabytes you will actually use, not the gigabytes you bought. For an unlimited plan, it is the plan price divided by your expected total consumption.

Worked example with Europe pricing published by both providers at the time of checking (USD, unlimited plans):

Neither provider lists a 14-day Europe plan, so the closest match is 15 days. The pattern is what matters: at one gigabyte a day, an unlimited plan costs you several dollars per gigabyte, and a fixed 5 GB or 10 GB package will usually undercut it. At three gigabytes a day, unlimited plans become cheap per gigabyte and fixed plans need repeated top-ups. Run the same arithmetic with the prices shown for your destination on the day you buy; a current Airalo package for your country will show data and validity before checkout, and Holafly's pages show the day-based price.

The chart is illustrative: it shows how cost per gigabyte on any flat-price plan scales with consumption, not a measured dataset.

Step 3: check the hotspot rule before anyone else relies on your phone

This is where the two models diverge most sharply for couples and families.

Airalo's help centre states that you can use a personal hotspot with the eSIM as long as the device and network support it, and its fixed packages carry no separate tethering cap; every shared gigabyte simply comes out of the pool you bought. Holafly's Europe page allows sharing 1 GB per day, with the total shareable amount matching the plan length, and its FAQ explains that the hotspot allowance is limited even on unlimited plans to protect the network.

For a solo traveler who occasionally tethers a laptop for email, Holafly's daily allowance is enough. For a couple planning to run one eSIM and share it, the allowance becomes the real ceiling: a 7-day plan gives 7 GB of shareable data in total. In that scenario, either each person installs their own eSIM or the group picks a fixed-data package with a pool large enough to cover everyone.

Step 4: decide by scenario

Honest limitations of both

Airalo's unlimited packages are not available for every destination, and where a fixed package runs out mid-trip, topping up costs time and attention; its help page also notes that the validity period itself cannot be extended, only the data. Some Airalo packages start their clock at installation rather than at first connection, so installing early can waste days if you did not read the validity policy.

Holafly's unlimited label does not mean unlimited speed: its FAQ says operators may reduce speed after a certain amount of high-speed usage, though it states the reduction is temporary. The hotspot cap is a hard constraint for shared use, and there is no cheaper light-use tier for the traveler who only needs maps.

Other providers such as Saily, Nomad or a local prepaid SIM bought at the airport are worth pricing for the same trip. A local SIM often wins on price for stays over two weeks in a single country, at the cost of a queue and a registration process.

Decision summary

Pick by daily data, then by sharing, then by price. Under about a gigabyte a day, a fixed package is cheaper and an unlimited plan is paying for insurance you do not need. Above two or three gigabytes a day, unlimited plans win on cost per gigabyte and remove the worry of running dry. If one phone feeds other devices, the hotspot rules decide, and fixed pools are the more predictable option. Whichever you choose, confirm the validity start rule and the country list on the provider's site before installing, and check availability and payment methods for your country there as well. When a fixed package matches your habits, compare Airalo's packages for your destination against the day-based price of the unlimited alternative and let the arithmetic settle it.
