What i love about this show is what happens after the story ends. Lots of story have this ending of epic quest, but i always wonder, does your happily ever after last forever? Thats when Frieren takes the direction to answer those questions. I love the approach, everyone loves conflict and major problems. Very few shows actaully go on to talk about what happens after “peace” in a more world view.
I would have suggested silent.link , while you can get a number not tied to your identity via esim, the main focus of numbers is a receiver for text and calls(also because it avoid people creating spam phone calls/txt). Which was originally for 2fa that only had cell # as an option. Also a number requires the user to be vigilant in paying their annual for it or they can lose the number. Also I think they can only cater for users in US, Canada and maybe UK.
