Holafly, Airalo or esimzu? eSIM providers honestly compared

There are many eSIM providers, and at first glance they look very similar. Yet at a comparable price, the experience can be quite different. This guide gives you the concrete criteria to compare providers fairly, so you can choose with confidence instead of just hoping for the best.

The five criteria that matter

CriterionWhat to look at
Price per gigabyteThe real measure, not the total price
Coverage on locationReliable local operators, 4G and 5G
Validity periodMatches the length of your trip
Payment methodcard payment, iDEAL or card
SupportFast help, ideally in your own language

Anyone who lines up these five points side by side almost always chooses well.

Price per gigabyte, not the total price

The first instinct is to look at the total amount, but that is misleading. Always work out the price per gigabyte in relation to the validity period. That way you can see which provider really offers the sharpest deal. More on this in the most affordable eSIM.

Coverage and payment matter too

A low price is worthless if the network is poor where you are. Check whether the provider uses reliable local networks at your destination, and whether you can pay easily, preferably by card.

The big names versus an independent provider

The well-known international platforms have an enormous catalog, but their payment options and support are not always tailored to travellers. An independent provider like esimzu focuses on card payment, instant delivery by email and customer support, all at a sharp price.

Frequently asked questions

Which provider is the best?

There is no single best provider for everyone. It depends on your destination, your budget and what matters to you in terms of payment and support. Use the five criteria.

How do I know if the coverage is good?

Choose a provider that uses solid local operators. Our destination guides list the coverage per region.

Is an independent provider cheaper?

For an international traveller, card payment, customer support and a sharp price often weigh just as heavily as a large catalog.
