The network coverage is mostly decent, though I don't often travel far beyond Durban. Mostly 4G where I go.
Pricing isn't quite as good as it used to be but still happy with the cost compared to the other two networks. Overall good value for what I pay
Customer service is not bad, I think the staff are overall empowered to do things within limit and they always act very quickly on requests. However the culture of the business is something to be desired, cannot upgrade to other contracts even though it means more revenue for them, if your contract ends in the middle of the month then you are charged for a full month. Be willing to listen to what your customers want, especially upper management.
Reception is generally okay in and around Durban (and I can roam onto Vodacom if need be). 2 biggest gripes with them - 1) Data is still far too expensive (I get that this is a country wide issue but Telkom Mobile has some pretty good deals on mobile data).
2) Almost every phone call I have between my Cell C number and any other number (or vice versa) gets dropped at some point. I'll be mid-conversation and then all comms coming in and out get disconnected. Really annoying not just when talking to friends or family but when you're on the line with clients or businesses and you have to phone them back or get them to phone on another number.
Lately when, for whatever reason, I'm forced to switch my data from my Telkom sim to my Cell C, my data (airtime) disappear really, really fast- this wasn't always the case. Coverage is also middle of the pack.
Switched to their fixed LTE from Rain. Apart from the daily disconnections (happens about two or three times a day for a few minutes at a time), reception is much better, speeds are incomparable, and they offer double the data for the same price.
Cell C / Afrihost support is pathetic. No service on their Fixed LTE in my town and all users are stranded. Afrihost's response "we waiting for feedback from Cell C" all the while we paying for no service.
