Go Phone Sim Card - International Calling
I've just bought a Go Phone SIM card for one month of calls for $25. I need 150 minutes/month to call a landline in Australia. I see there is a $5 Int'l feature. It reads like I get 250 minutes of Int'l calls for $5, but elsewhere I see per minute charges of about 9 cents/minute and still elsewhere per minute rates of about $1/minute. If I buy the $5 Int'l feature how much will it cost me to talk for 150 minutes?
Finally, I paid $25 for one month of calls, so my account balance is now zero. When I try to buy the Int'l Calling feature I'm always asked to pay another $25 to recharge my account. I just want to add $5. Can I do this?
