iMore Question
I am getting ready to go to Europe from the United States. I was hoping not to have to purchase an international plan from AT&T. I downloaded Viber, but in reading several of the comments/posts it says on some 3G networks your carrier may charge you, make sure you have enough data available or you may be charged, make sure you have unlimited calling so as not to be charged. Otherwise use WI-FI. Can someone please explain in detail the usage of Viber? Henry
