Hey there! Hoping someone might be able to help me. I'm curious if anyone knows which video chat program uses the LEAST amount of data but still works well. The reason I ask is my husband is a truck driver and wants to chat with our son while he's on the road but he is usually only using 3G/4G in most places. I am usually on WiFi all the time, so for me, it's not really an issue, but we're just concerned about going over our data allowance if we video chat "too much" while he's not on a WiFi network. I currently have Skype and Google Talk on my phone and have used both with no issues, although I do prefer Skype so far. I have heard that uses a ton of data. Any thoughts? Thanks in advance!!
