Airalo Disadvantages: What the Review Sites Leave Out

Read this first

We sell travel eSIMs, so we are not a neutral party on this question. Treat everything below as a competitor's account and check the prices yourself — Airalo publishes them openly. We have tried to list only things that are verifiable rather than things that are merely unflattering, and the last section is about where Airalo genuinely wins.

The disadvantages in one paragraph

Airalo is the largest travel eSIM brand and generally the most expensive of the mainstream options for the coverage you get. It resells the same local carriers as everyone else, so you are paying a brand premium rather than a network premium. Most of its local plans are data-only with no phone number, unused data does not roll over, and top-ups are frequently priced above the original plan. None of that makes it a bad product — it makes it a product that a lot of people buy without checking what the identical connection costs elsewhere.

1. You are usually buying the same network, at a higher price

This is the disadvantage that matters most and the one review sites skip, because "which carrier does this eSIM actually use" takes work to find out. Travel eSIM providers do not own networks. In Japan, Airalo, Saily, Nomad, and Flysimio all route through the same handful of Japanese carriers — mostly NTT Docomo and KDDI. The signal in your hand is identical. What differs is the markup.

So the question is never "is Airalo's network good" — it is fine, because it is the local carrier's network. The question is what the same connection costs from someone else. On our Japan comparison, the spread between the cheapest and most expensive provider on identical NTT Docomo coverage was roughly 2x per gigabyte.

2. Unlimited plans carry a steep premium

Airalo's Japan unlimited ladder, checked on 6 August 2026, looked like this:

The trap is that "unlimited" sounds like the safe choice. For most trips it is the expensive choice. Typical travel usage — maps, messaging, a few uploads, occasional streaming on Wi-Fi-free evenings — runs around 500 MB to 1 GB a day. If that is you, a per-day or fixed-data plan costs a fraction of an unlimited one. Work out your actual number first; our data calculator does it in about fifteen seconds.

3. Most local plans are data-only — no number, no calls, no SMS

Airalo's local eSIMs are, with few exceptions, data plans. You do not get a local phone number and you cannot send or receive normal SMS. In practice this matters in two situations: receiving a bank or two-factor code by SMS, and any local service that texts you — a restaurant booking, a taxi app, a delivery. WhatsApp, iMessage, Signal, and internet calling all work fine because they run over data.

This is not unique to Airalo — it is true of nearly every travel eSIM including ours, and it is why the standard advice is to keep your home line active for SMS while the travel eSIM carries data. It becomes an Airalo-specific complaint only because the marketing rarely says it plainly, and people arrive expecting a phone number.

4. Top-ups are often more expensive than the original plan

Running out mid-trip is the moment you have the least leverage, and top-up pricing tends to reflect that. Check the top-up rate before you commit to a small starter plan on the theory that you will extend it if needed — the two-step route frequently costs more than buying the right size once. This is an industry-wide pattern rather than an Airalo invention, but Airalo's starting plans are small enough that a lot of people hit it.

5. Unused data expires and does not roll over

Buy 5 GB for 30 days, use 2 GB, and the remaining 3 GB is gone when the window closes. There is no carry-over to a future trip and no partial refund. Again, standard across the industry — but combined with the pressure to over-buy "just in case", it means a lot of travellers systematically pay for data they never touch.

6. Refunds are limited once the eSIM is installed

As with most eSIM providers, once a profile has been installed and used, refunds become discretionary rather than guaranteed. Read the current policy on Airalo's help centre before purchase rather than relying on any third-party summary, including this one — refund terms change more often than prices do.

Where Airalo is genuinely the better choice

• Country coverage. Airalo's catalogue is one of the widest available. For genuinely obscure destinations it may be the only provider with a plan at all, and coverage beats price every time.
• Brand maturity. It is the oldest and largest travel eSIM company, with a properly staffed support operation and an app that has had years of polish.
• Multi-country regional plans. If you are crossing many borders and do not want to think about it, Airalo's regional bundles are competent and well-documented.
• Familiarity. If someone you trust has used it successfully, that is worth something real on a trip where connectivity failing is genuinely disruptive.

Our honest position: for a single well-covered country, check what the same carrier costs elsewhere before defaulting to Airalo, because the gap is usually large. For unusual destinations or complex multi-country routing, Airalo's breadth may well be worth the premium.
