I don't think this is really a replacement for the offering that Cape is proposing. Airalo are data only eSIMs and target consumers who need short-term data plans while traveling abroad. This is not a replacement of your primary carrier service and doesn't give you a phone number. Additionally, other than the transient nature of the temporary eSIM you buy, there are no notable privacy-focused features behind Airalo.
Not saying Cape follows through with its claims, just saying these are not really comparable offerings.
