Im getting "No service" in the Centurion Area, tried with 2 diffrent phones.
Just to Update on this, I phoned CellC and the technical support says my sim is faulty. So I drive down to the local Checkers to buy a new sim, arriving at the checkers CellC is registered again, Full bars and HSDPA is connected.
I drive back to work, and again, No Service.
So obviously the problem is on CellC's side and not mine, I almost did a unnecessary Sim Swop

The Problem is still not fixed though, "No Service", I see most traffic lights in the area are out, maybe a power issue CellC Rep?, maybe something to do with last nights weather?
Regardless, today was the first time i'm getting "No Service", But i have issues with CellC every day here in Centurion (at work), There is seriously something wrong with the tower we connect to here, i have had the poor internet signal from last year, on my old Iphone5, my S4, my S5 and now on my G3. When i'm home my signal and Internet works like a dream.
Update
11:40, CellC is registering again, phone shows HSDPA, but still no internet.
12:00, Internet working again.
