Thanks to fitwxc, a lot of people can use the smartphone browsing the internet. I have a question related to the WM phone.
We use the prepaid plan, so making phone call wiout using minutes is important. What software do you use to make the call and what service provider do you use to make the call?
I know some sip client, such as fring, portgo, etc. Which one is better?
We can use GV callback function to make free US call. But I feel there are some lagging. It is difficult to carry on a conversation. Do you use any low cost provider, such as localphone, voipdiscount, etc? What is your call chain looks like?
Your answer is appreciated!
