I have tried every optimization of the 3G signal of Zain or MTN here in Ghana, and I still cannot use skype to call a landline.
3G is not fast enough for skypie, I have been using tether.com to tether my computer to my BlackBerry with a Verizon global connection. I make sure the cell tower is line of site, I can have a screaming fast packet rate, and still I cannot talk.
When I call a land line, I can hear the other person perfectly, but the words I speak are mumbled.
I have successfully used the 2G and 3G networks to talk computer to computer, and I can talk on Yahoo Messenger computer to computer.
I am waiting, I need 4G.
