I'm back with an another post... for some reason. This time I'll talk about esims. So tf are those esims anyway? Esim stands for embedded subscriber identity module(I think), it's basically a piece of hardware in your phone which saves all of the info, which is required to connect to a mobile network. To simplify this, it's a normal sim, but embedded in your phone. Here my thoughts about them: Pros: takes less space, free second sim slot, fairly easy to add it to your phone(depends on your phone's UI) Cons: no user authentication everytime phone tries to connect to the network, changing devices can be a pain(since you need to get a new qr code issued), saved sims stay on your phone after a factory reset. I'd say that it's a nice piece technology, but I think that it will kinda make our privacy situation worse, because esims force you to use a single device. update: it seems like enabling a pin verification on esims is possible, but I still think that moving them between devices is a bit of an issue which iOS kinda solves(between apple phones only). and I am saying kinda, because transferring them to an android device is not a thing. Stock google is trying to solve this as well, but I don't really know if it's really a thing now. I just know that it is not a thing in custom roms
