I can. I have used them extensively while travelling (always local offers - I never needed a sim for multiple countries but a European one is barely more expensive than a single EU country one for example). Airalo sells local esim for something like 200 countries with prices which are competitive and offering which are often better tailored to travellers. In plenty of countries if you try buying straight from a local provider you can’t buy low amount of data or have to get voice with it. Meanwhile Airalo allows you to buy 1, 5 or 10GB for very cheap and topping up is pushing a button in their app. I meant it when I said it was insanely more convenient.
