It's very user-friendly interface makes it simple for users who are new at using this kind of platform! You can easily connect with your colleagues or clients from anywhere in the world within minutes. There is no limit as far how many people you want connected together but there might be some limits depending where you live (e.g., certain countries). With mobile day we have made our calls more flexible so now I'm able to make them anytime of the night/day even when not physically present which really helps us out since sometimes deadlines get missed due to time differences & travel delays.
