Everyone who has a cell phone has the ability to text, and if you have an iPhone then you know that we (yes I'm an iPhone user) have iMessage. A messaging service exclusive to iOS. Well T-Mobile has announced that they will be launching an advanced messaging service for Samsung phones.  It will have features such as the ability to send large picture files and you can see when the recipient is typing back. Like those dots in iMessage.  Right now the feature is only available on the Samsung Grand Prime and of course is exclusive to T-Mobile.  Samsung Galaxy S5 and S6 users will eventually be given the feature via a software update.
