Just picked up a GoTalk Mobile SIM card from Crazy Johns. Activated the card on line and began calling overseas. Call Rates are cheap, however there is a reasonable flag fall of $0.30 per call. The international rates are very attractive though. India 2.5c , USA 4c UK 4c South Africa 4c Japan 0.5c, (per minute) all these from a Mobile Phone. The SIM card also comes with a Calling Card if you want to call from a Land Line an it seems like the flag fall rate changes to 0.15c per call. The phone card usage charge is debited to you mobile pre-paid account. Service seems to work OK, checked my account on line and I am being charged the correct rates.
International/Domestic SMS's are also cheaper than most at $0.125c each. Domestic calling rates are 20c per minute.
GoTalk to GoTalk Pre-paid calling the website states as being free and Data is 0.10c per Meg, a little expensive, but not bad for the odd casual use. Credit on the Straight Talk plan lasts 90 days.
I would be curious about the GoTalk to GoTalk being free 24/7 as I have not used this.
PS when you recharge they give you a 20% BONUS credit
Great post, family is all using this and we get to call each other for free anytime any day.
