I recently replied to a question on the MyBroadBand forums. Ettiene69 asked: “Is there any VOIP App or service provider which I can use on my iPad, which IS ACTUALLY CHEAPER than normal Telkom or Cell Phone Rates?”
I provided this 3 step solution:
Step 1: Install the MobileVoip app (available for iPhone, iPad, iPod, Symbian, BlackBerry, Android, Windows Phone): iStore link here: http://itunes.apple.com/app/mobilevoip/id362528311?mt=8
Step 2: Register and purchase 10 Euros of any Voip provider - for South Africa I recommend Rynga: http://www.rynga.com/calling-rates.html#letter-S
Rynga rate for South Africa (Landline) FREE (for 120 days, then R0.31c per minute) [Telkom rate is R0.57c per min]
Rynga rate for South Africa (Mobile) R0.558 per minute [Telkom rate is R1.35 per min]
Telkom rates from here: http://www.telkom.co.za/general/pricelist/automaticexchanges_worldcall.html
See Rynga’s rates list here: http://www.rynga.com/en/calling-rates.html
Step 3: Purchase data for your iPad - for low usage per month, I recommend CellC prepaid:
Rynga rate for South Africa (Mobile) 56c+16c=72c per minute [Telkom rate is R1.35 per min]
So, with all 3 steps done you should be able to take your iPad anywhere in South Africa, start up the MobileVoip app and make calls cheaper than using Telkom and cell phone rates :) :)
At home or when within range of WiFi point, switch to WiFi and save even more.
Let me know if it works for you.
