I bought 14 300GB eSIMs for Europe and they all stopped working when they reached 35GB. I filed a complaint with AirHub and they told me they didn't actually provide 300GB and only offered 35GB. I asked for a refund and they never gave it to me. That company is a scam. Stay away if you don't want to be scammed.

AIRHUB is a SCAM. They are thieves who steal your money and give you eSIMs with less GB than they offer.

Airalo

AJused in Portugal 🇵🇹

I live in Portugal and travel frequently, so using an eSIM provider seemed like the logical choice. Among the many options available, I chose Airalo for its competitive packages. Initially, the service worked as advertised for about a month, but since then, I’ve faced nothing but persistent and infuriating issues.

It appears that national networks have blocked Airalo from connecting, rendering the service practically useless. Unfortunately, Airalo’s support has been utterly unhelpful. Despite countless support tickets, messages, and screenshots, there has been no resolution.

What’s worse, Airalo refuses to provide a refund, instead forcing customers to accept Airalo credit. This so-called “credit” is completely worthless to me since their service does not work.

This has been a massive waste of time and productivity, especially since I rely heavily on mobile data for my work. The lack of accountability and support from Airalo is both frustrating and unacceptable.

I strongly advise anyone considering Airalo to avoid them at all costs and look for more reliable alternatives. Do not waste your money or your time.

Airhub

Frankused in Portugal 🇵🇹

If I've listened to the previous review, should have gone with their competitor ETxxx instead. Landed in Europe, activated it, connecting flight arrived in Funchal, connected got no data allowances. Took online chat 48 hours to resolve. Then found out the included voice minutes did not work, still repair in progress. The only good thing is online chat is available everyday including Sat & Sun.

The esim activated, but the data didn't work thereafter. I tried to contact their customer support multiple times thereafter and they didn't get back to me. Completely useless. Possibly even a scam.

Fast 5G speeds in Madeira, Portugal (and the airport in Lisbon). Only downside is you can't check data usage — though with 30GBs for our seven-day trip we didn't really need to.

What are the major mobile networks available for a travel eSIM in Portugal?

Portugal's mobile network infrastructure is primarily supported by the following major Mobile Network Operators (MNOs):

MEO: Operated by Altice Portugal, MEO offers extensive nationwide coverage and a wide range of mobile services.
NOS: As part of NOS Comunicações, NOS provides comprehensive mobile services, including voice and data, across Portugal.
Vodafone Portugal: A subsidiary of Vodafone Group Plc, Vodafone Portugal delivers robust mobile services with significant market presence.

Notable examples include Lycamobile, which operates on MEO's network and offers prepaid SIM cards with international calling plans, and Moche, a brand targeting youth customers with services on the MEO network. It's important to note that most travel eSIMs rely on MNO infrastructure rather than MVNOs.
