We normally communicate via email and Instant Messengers like Skype/MSN/Yahoo however one member of your team will have a local phone no and you can contact your team anytime as they are always just a phone call away. Additionally we also use an Instant Messenger for smartphones “whatsApp” through which you can be connect to your team 24/7 on the move.
How will the communication works? How will I be able to communicate considering time zone differences? What if I have an issue in the middle of the night?
