Back in the day, kuna wakati Safcon with their con games, were running a promotion ya calling rates. The rates used to alternate between 50 cents, and 8 shillings per minute depending on your location and the time of the day. You just needed to enable/allow push messages on your phone so they would send a push message displaying how much you would be charged per minute if you made a call at that particular location and time.
Ulikuwa unaweka credo ya 20bob ama 50bob then unangoja rate ishuke (to at least 2 bob and below) ndio uongee dakika mob. Sasa upuzi kubwa ilikuwa ati ungepata inashow rate ni 1bob ukiwa sitting room then uamue upige simu alafu bahati mbaya uende to a different room, rate inatoka from 1bob inaruka hadi 8bob na saio uko kwa call already. Unaongea one minute then unaskia ile beep ya low credit ti ti ti ti.
Hio mambo ya ku enable push messages was them conditioning us to allow them to track our location at all times, even before 3G. Even the spam promotional messages the sons of lucyfar from all these carriers keep sending us are designed to siphon your device info remotely, even with your data turned off. Kama sio missionaries maybe bado telepathy would be the in thing.
