Airalo vs Holafly for Port Calls: Honest Test
Choosing between Airalo vs Holafly for port calls comes down to one question that has nothing to do with price: do you need to share the connection, or just use it on your own phone? Holafly sells unlimited data but restricts hotspot use on most plans, and Airalo sells a fixed bucket of gigabytes with hotspot allowed. For a six-hour berth where you want to burn through a video call home, Holafly usually wins. For a crew that pools one connection in the mess room, Airalo is the safer buy.
That is the short answer. Below is the longer one, based on how these plans actually behave when you step off the gangway in a port you have never seen before, with an hour of shore leave and a phone that has been in airplane mode for eleven days.
Why eSIM choice is different for seafarers
The difference is that your usage is compressed into short, unpredictable bursts. A tourist buys a 7-day plan and uses it for 7 continuous days. You buy a plan, use it hard for four hours in Rotterdam, then vanish into the North Sea for a week while the validity clock keeps running.
That single fact breaks most of the advice you will find online. Reviewers compare cost per gigabyte over a full trip. What actually matters at sea is cost per usable session, and whether the plan is still alive when you next see a berthing rope go over a bollard.
There is a second difference. You often do not know your next port with certainty. Charters change, bunkering ports get swapped, a delay in the Bosphorus turns a Constanta call into a Piraeus call. A plan locked to one country is a gamble. A regional plan is insurance.
The third difference is hardware. Ship cabins have thick steel and the signal at the quay can be poor even when the port city has good 5G. That pushes some crew toward a portable travel router in the cabin to squeeze a usable signal out of one good spot near a porthole. If you plan to do that, hotspot policy stops being a footnote and becomes the whole decision.
Airalo vs Holafly for port calls: the core comparison
Here is the practical breakdown. Figures are ballpark as of July 2026, and both companies change pricing and policy regularly, so check the official page before you buy.
| Factor | Airalo | Holafly |
|---|---|---|
| Data model | Fixed GB bucket (1 GB, 3 GB, 5 GB, 10 GB, 20 GB) | Unlimited data on most destination plans |
| Validity | 7, 15, 30 days, some 90 and 180 day options | Typically 1 to 90 days, chosen at purchase |
| Hotspot / tethering | Allowed on standard plans | Restricted or capped on most unlimited plans, check the destination page |
| Typical entry price | Roughly $5 for 1 GB / 7 days on many countries | Roughly $19 for 5 days unlimited on a single country |
| Regional plans | Strong: Europe, Asia, Middle East, Africa, plus a global plan | Available, fewer regions, priced higher |
| Top-up | Yes, keeps the same eSIM profile | Depends on plan, often you buy a new one |
| Speed policy | Full speed until the bucket empties | Unlimited with fair-use throttling after a daily threshold on some plans |
| Phone number | Data only on most plans | Data only |
| Best for | Multi-port rotations, crew sharing, unpredictable schedules | Single long port call, heavy video, one device |
The table hides one thing worth saying out loud. Holafly's "unlimited" is genuinely useful when you have four hours and want to video call your family without watching a counter. Airalo's fixed bucket is genuinely useful when you have eleven ports in three months and want each one to cost you two dollars.
The hotspot rule that decides most cases
Hotspot policy is the single most decision-relevant difference between the two. Airalo permits tethering on standard plans, so one crew member can buy 10 GB and share it. Holafly limits or blocks hotspot on many of its unlimited plans, which makes sense from their side: unlimited plus unlimited sharing is a business model that does not survive a container ship's worth of crew.
If your plan is "I buy the data, three of us split the cost, we all use it in the mess room", Holafly is the wrong tool. Read the specific destination page before assuming, because Holafly has adjusted this policy on some plans and the details vary by country.
Validity clocks and the dead-plan problem
A plan's validity starts when it connects to a network, not when you buy it, which is the one piece of good news here for both providers. You can load the profile in the engine control room a week out and it stays dormant until you land in port.
The problem is what happens after activation. A 7-day Holafly plan bought for a Rotterdam call is dead by the time you reach Algeciras. A 30-day Airalo bucket with 6 GB left on it is still alive and still has the same profile in your phone. For a rotation with several calls in a month, that difference compounds fast.
What actually happens when you go ashore
The first two minutes are the same on both. Your phone has been on the ship network or in airplane mode, you switch the eSIM line on, and nothing happens for thirty to ninety seconds while the profile hunts for a partner network. This is normal. It is also the moment most people panic and start toggling settings, which makes it slower.
The concrete step that saves you every time: before you leave the ship, turn data roaming ON for the eSIM line specifically, and set the eSIM as your mobile data line while leaving your home SIM active for calls only. Both apps tell you this. Almost nobody reads it, and then blames the eSIM.
A second concrete detail. Port terminals are frequently in industrial zones several kilometres from the city centre, and coverage there can be one bar of a partner network you have never heard of. Neither Airalo nor Holafly can fix that, because both are reselling access to local carriers. What differs is which local carrier they land you on, and that varies by country. In some ports one provider will connect and the other will crawl. This is not a quality ranking of the two companies, it is a routing lottery, and the only real hedge is having a second option loaded.
That hedge is cheap with Airalo, because a 1 GB backup plan costs a few dollars and sits dormant until needed. It is expensive with Holafly, because their minimum purchase is a multi-day unlimited plan.
Honest cons: Airalo
Coverage quality is inconsistent between countries. Airalo is a reseller, and the partner carrier it lands you on in one country can be excellent while another feels like 2015. You will not know until you land.
The gigabytes go faster than you expect. Eleven days of queued app updates, iCloud photo backup, WhatsApp media sync, and a Windows laptop that decides now is the time. A 1 GB plan can evaporate in fifteen minutes before you have made a single call. Turn off automatic updates and background app refresh before you connect.
Customer support is chat-based and slow. When a profile fails to activate at 22:00 in a port where you have two hours left, a support ticket is not a solution.
Top-ups can be more expensive per gigabyte than a fresh plan. Check both prices before topping up, because it is often cheaper to buy a new plan.
No voice number on most plans. If you need to receive an SMS from a bank or an agent, this is data only and you need your home SIM alive for that.
Honest cons: Holafly
Hotspot restrictions on most unlimited plans. Already covered above, and it is the one that catches crew out most.
Poor value for short calls. A five-hour berth on a five-day unlimited plan is a bad trade when you use two gigabytes. You are paying for four and a half days you spend at sea.
"Unlimited" comes with fair-use throttling. Some plans slow down after a daily threshold. It is still usable for messaging after that, but do not plan on downloading a film in hour six.
Fewer regional options. For unpredictable routing, this hurts. A Europe-wide Airalo plan covers a schedule change. A Holafly Spain plan does not cover a diversion to Marseille.
Higher entry price. There is no cheap experiment. The smallest useful purchase is a real chunk of money, which makes carrying a backup uneconomic.
Who should not buy these
Do not buy Holafly if you sail a coastal rotation with frequent short calls. You will burn money on validity you never use. Buy a regional Airalo bucket and top it up.
Do not buy Airalo if your one shore day per month is entirely a video call day. You will run out mid-call and buying more from a spotty connection is miserable. Buy the unlimited plan and enjoy it.
Do not buy either if you expect them to work at sea. They are terrestrial cellular plans. Twelve to twenty miles offshore, depending on the coast and the tower, you have nothing. Anything beyond that is satellite territory, and the honest overview of what works between ports is in the guide to how seafarers stay connected at sea.
Do not buy either as a replacement for ship internet. If your vessel has Starlink for crew use, an eSIM is a port-call supplement, not a primary connection. Budget accordingly.
Do not buy if your phone does not support eSIM. Sounds obvious. Check the model list first, because a surprising number of mid-range Android phones sold in crewing hubs do not have it, and some carrier-locked phones block eSIM even when the hardware supports it.
How to choose in ninety seconds
Ask three questions in order.
- Will anyone else use this connection? If yes, Airalo. Hotspot policy settles it before anything else matters.
- Is this one long call in one country, or several short calls across a region? One long call in one country favours Holafly. Several calls across a region favours an Airalo regional plan.
- Do you actually know your next port? If the schedule is soft, buy regional, and buy the provider whose regional coverage matches your trade area.
If the answers are split, the default that goes wrong least often is a regional Airalo plan with a generous bucket, because it survives a schedule change and it can be shared. Holafly is the specialist tool for a specific, known, heavy-use day ashore.
A practical loading routine before a port call
Load the profile at sea, over ship WiFi, at least a day before arrival. Both apps let you install the eSIM without activating it, and installing over a weak ship connection at the last minute is how people end up with a half-written profile.
Label the line clearly in your phone settings, something like "PORT DATA", because after four rotations you will have several dormant profiles and no memory of which is which.
Before the gangway goes down, do three things. Turn off automatic app updates, turn off photo cloud backup on cellular, and switch the eSIM to be your data line with roaming enabled. Those three settings are the difference between a gigabyte lasting an afternoon and a gigabyte lasting ninety seconds.
If you are pooling the connection with shipmates, agree the rules before you connect. One person hotspotting for four people who are all syncing photo libraries is a 10 GB plan gone in under an hour.
Security note that people skip
Public port WiFi in terminals and seafarer centres is the reason to have your own eSIM data in the first place. Terminal networks are frequently open, unencrypted, and shared with everyone in the building. When you must use one, run a VPN, and there is a rundown of what actually holds up on marginal maritime connections in the VPN guide for cruise ship crew.
Your own cellular data through either eSIM is meaningfully safer than an open terminal network, which is a real argument for buying one even when free WiFi exists.
FAQ
Does Airalo or Holafly work while the ship is at sea?
Neither works once you lose sight of the coast. Both are terrestrial cellular plans that connect to local mobile towers, so you keep signal roughly ten to twenty miles offshore depending on the coastline and tower placement, then nothing. Anything further out needs a satellite service.
Can I share an Airalo or Holafly eSIM with other crew members?
You can share Airalo on standard plans, because tethering is permitted. Holafly restricts or caps hotspot use on most of its unlimited plans, so sharing is unreliable there and may be blocked entirely. If crew sharing is the point of the purchase, buy Airalo and check the specific plan page before you pay.
Does the validity period start when I buy the plan or when I arrive in port?
Validity starts on first connection to a network, not at purchase, for both providers. That means you can install the profile days in advance while at sea and it stays dormant until you switch the line on ashore. Install early over ship WiFi, because installation itself needs a connection.
Which is cheaper for a seafarer over a three-month contract?
Airalo is usually cheaper across a rotation with multiple short port calls, because you pay per gigabyte rather than per day and unused data carries on to the next port. Holafly can be cheaper for a single heavy usage day, though it stops making sense the moment you have more than a few calls in a month.
Can I keep my home phone number active while using these?
Yes, on any dual-SIM phone. Keep your physical SIM active for calls and SMS while setting the eSIM as your mobile data line, and turn roaming off on the home SIM to avoid charges. This matters if you need bank verification codes, since neither eSIM gives you a usable phone number on standard plans.
What happens if the eSIM will not connect when I get ashore?
Check that data roaming is enabled on the eSIM line first, because this is the cause in most cases. Then manually select a network in your phone's carrier settings rather than leaving it on automatic, and give it two full minutes. If it still fails, restart the phone once, and if that fails, the profile likely needs reinstalling, which is why a dormant backup plan is worth carrying.
Verdict
Buy Airalo if you sail a normal rotation with several port calls, an uncertain schedule, or shipmates who will want a share of the connection. Buy Holafly if you get one substantial day ashore in a known country and want to spend it on video calls without watching a data counter. The gap between them is smaller than the marketing suggests, and both will fail you in a port with bad partner coverage, which is the real argument for keeping a cheap backup profile loaded at all times.
If you want the wider picture before committing, the comparison of eSIM providers that hold up between port calls covers the other options in this market. For most crew, though, the answer to Airalo vs Holafly for port calls is a regional Airalo plan for the rotation and a Holafly unlimited plan bought only for the one long shore day you know is coming.
