Modems

I have a big problem with Vodacom with all the loadshedding we have you would think they would give you a modem with a battery but no, everytime the electricity goes off so does the modem they get the alcatel modems from China where they don't have loadshedding that is why they don't need batteries in the modem there but what about us sods living in south africa that has permanent loadshedding why is Vodacom doing nothing about it?
