It can be frustrating while you work and cannot reach some of your important clients or colleagues, especially when you are in a pinch and have to reach them somehow. Working in IBM, I’ve noticed that without having tethering connection + VPN from your smartphone, this was near impossible until I’ve found an application that allows users to log-in remotely using your phone data-plan. There are many free applications such as, QuipIM, lotus-sametime-for-android, and so on… If you have an iPhone (like myself), QuipIM is battling away with the apple corp to get them to approve their app version on app-store. Until then, I’ve found this useful site for you to use this site HERE and HERE2. Good thing about this site is that, it’s web application, so apple cannot have any jurisdiction over the implementation. Try it today.
