The plan seemed too good to be true, but it was (for a while at least). Alas, all good things must come to an end, as Helium Mobile has now discontinued the Zero Plan without offering much of a reason.Reddit user mkzio92 noticed that Helium Mobile removed all support pages related to the Zero Plan and updated their website to say, “The Zero plan is not currently being offered.”
