THEY REUSE CODES THAT WON'T WORK. - I have used Airalo a few times now. The first 3-4 times were as normal as can be expected, recommended it to everyone as an eSim provider option not having used any other providers. However, this time was different. Went to buy a new eSim upon arriving, purchased it, went to install it immediately as I normally would, and was hit with a "This code is no longer valid" error message. With no options available. So I tried again about 20 times, tweaking something each time (updates, restarting, etc) So I contacted the support in the app. An hour had passed so I got a different eSim and got going to my hotel. 6 hours later they contacted me asking me to run through the setup multiple ways - ways I had tried - immediately getting hit with the same message. After some back and forth they wanted me to turn on one of the previous ones I had used with them and tried suggesting that it was actually that one. I, not being a complete idiot, didn't fall for that. After a bit more back and forth the support agent just said we appreciate your feedback and then closed the chat. Although 4/5 times it worked as it should - in the event you get a code that's already used- seems like you can just say goodbye to whatever you paid with no real help whatsoever.
