Last week, before the iPhone officially launched in SA, MTN & Vodacom released their carrier updates for the iPhone. A carrier update is the file that is used to populate all the network settings on the iPhone, and is pushed out either via iTunes or over the air to your handset.I dug a bit deeper into the actual files that are used to populate these settings to see what they entailed.
Because this was the first time MTN has offered the iPhone, it was basically a new carrier file. Vodacom didn’t change too much from their previous files.most notably in the MTN file was the exclusion to not allow you to edit carrier settings. They also excluded Visual Voicemail, as they do not offer this service yet.
There also seems to be some issues with MTN MMS on the iPhone, according to a couple of queries I have received. The only thing I can think of would that the APN is not active for your specific contract, as it may be specific to the iPhone. Best bet would be to call MTN ?
Below are 2 screen shots of the settings in each file. You will need to click to enlarge the image, as they are pretty big.
