Same with me, my one and only son is also @UP, staying Hatfield/Arcadia area. For a decent voice call he has to go outside, happily his student place has ADSL, but also that data connection is far from perfect. My experience with Data using my speed stick and laptop in many areas of Gauteng on Cell C is that it leaves a lot to be desired. Looks like they are overselling the network. And rather work on that one than that Grand Head Office near the Buccleugh interchange. Here in a small rural town, everything seems to be OK.
