Mtn loadshedding

I have noticed that when we have load shedding and there is no electricity the MTN network also goes on load shedding. I dont understand how electricity can affect the network while vodacom works perfectly well. in my househould we have five phones that uses the mtn network but all of them are not working. its funny coz both my phones are LTE but only vodacom works fine but this MTN LTE works if theres electricity. what kind of a network goes off when there is load shedding? please sort it out coz u costing us big tym. if I want to phone someone in an emergency and they are using mtn then I will be stuck because of load shedding. really I dont understand if your network is affected by load shedding. please do something abbout this please its not on. even when I am in Bryanston there is no network when there is load shedding. since last year I noticed this because I wanted to make sure if this is real and it is. no man this is really not on and thats why I am reporting this.
