I'm such an e-sim pusher but another thing I have discovered about them is if you blow through your data plan in a month and don't want to pay the inflated prices of your evil oligopolistic telecom, you can also get a cheaper e-sim from a 3rd party supplier (I like Airalo) to act as a stopgap.
They're also just really good pre-paid plans if you don't want standing monthly data packages. So easy to use.
