Hello friends, One of my neighbors is looking for an internet plan. They are an elderly couple, recently their son from abroad sent them a tab that has only wifi connection, so that they can have video calls with them when needed. They dont have any pc or laptop. My guess is its the first time they would be using internet.Since I use spectranet and its quite good at my place i suggested them the same, where as their friends and relatives gave them other suggestions. They are yet to make a decision.So my question is, in terms of speed what is the minimun speed plan required to make video calls over skype and how much data one would consume over calls with little browsing in a month? I need to know so that I can suggest them a limited plan that is economical as well.Thanks!
