Yes but Apple has convinced a large swath of them that they must have an iPhone to be able to have any conversation with friends simply due to the conveniences of iMessage.
They also went out of their way to make SMS conversations harder to read the text by making the green just annoying enough of a color that it actually makes it harder. There are other things but that’s the gist.
A lot of laws (in the States at least) require the capacity to be only what the current student enrollment numbers are at, or at what the enrollment numbers are projected to be when the building is built. This is why you almost always see brand new schools completely full within a few years of being built if they have any sort of normal growth AND why these types of mobile buildings get built. They just don’t have any room whatsoever for the student growth. Some schools have started opting for “modular” buildings after the fact to get around this. They’re basically permanent buildings but the building is designed so that it can accommodate just about any size room, whether it’s offices, classrooms, small gyms, etc… This allows for the building to be built and ready to go but also not require that it not be an “empty” room so they can kinda sorta have spare classrooms when needed.
