First, this needs a more unique name. When searching for "messaging" and/or "service" too many hits came up. Maybe a more unique product NAME is in order.
Second, there should be a phonebook icon to look up people. If you attempt to search by name, nothing comes up. In fact, for me I found only if i type in 2 characters, do 'hits' come back. and usually they had to be numbers. and the hits did not necessarily have anything to do with the numbers!
example: 40 or 07 for 407, should return my 407 friends, right? no. someone had a "04" in their x04x part of their phone number and it was returned as a hit.
NEEDS MORE WORK, VERIZON.
