Typical Vodacom response hinting at things to come…“However, said Boorman, as new services come to the market they think that there are some important issues for the various stakeholders to look at.
These issues include the use of spectrum by unlicensed entities, as well as the potential impact on tax revenue and employment,” said Boorman.
I used to buy the 2+1gig bundle from Telkom Mobile, but then I realised I almost always lose around a gig at the end of the following month since I have wifi at home and work. Now I buy ad-hoc bundles.Is that good or bad? On your current data package?
I also think I've messed up somehow. I'll redo my test a little later.That's quite a lot for voice only. Was it video too? Or if not, was the audio quality superb?
Lets do some maths for voice only:
1. Assume audio rate is 64kb/s (quite high, but lets be liberal for worst case scenario)
2. So thats 8KB/s, resulting in 480KB after 1 minute.
3. Assuming R2/MB, that would be about R1/min for a call.
1. You can get away with a bitrate of 32-40kb/s for voice only, resulting in a saving of 25c-50c from the R1/min in (3) above.
2. In (2) above, the 480KB assumes a constant bitrate. But, after a hangouts test yesterday, I noticed that the app detects silence, so it arguably sends nothing in this case. So unless you're a chatterbox, this can also result in savings. May be complicated by the fact that its duplex (x kb/s both ways), so we can discard this for now.
3. (3) above assumes R2/MB. Bundles can greatly reduce the price of a call per minute. Assuming CellC's R15/100meg, (3) above can be reduced to 7,5c/min.
Moral of the story: just like IMs killed off the SMS, these services can kill off voice.
Maseko probably too busy changing number platesTelkom was asked for comment, but the company did not respond by the time of publication.

I did a balance check before and after the call. It could be that something was concurrently connected and up/downloading in the background.
Just tested it. Was on the phone for about 6-7 minutes and used 3.39MB of data. The call quality was amazing even when the person on the other end is sick. Much better than network calls.
I didn't see any free voice calls on Hangouts?
Only in the US and Canada?
