Had a nightmare getting a holiday only e-sim in Australia

Couldn’t set up easily because no wifi

then I just simply could not cancel the damn thing… It required being in Australia, and like the article needed a SMS code and the support was only contactable Australian working hours… who wanted the SMS code again.

So once back in Blighty there was no way… had to cancel the credit card to stop payments

So you are at the mercy of the competence of the provider
