Features:

• Uses your device's existing contacts list.
  Your contacts with a phone number in the "Mobile" category will automatically appear in MoblMsg.
• Simple interface.
  Everything you need is in one simple window. Switch from Inbox to Outbox to Compose with a click of a button.
• No more endless scrolling through your list of contacts.
  The MoblMsg contact list is limited to only those people you can send a text message to which makes scrolling for a person very quick.
• Quick and Easy Group list creation
  Just select the names and save as a group. The groups you created are displayed at the top of your contacts list for easy retrieval.
• Exclude or add persons before sending a message to a Group list.
  Currently Windows Mobile doesn’t allow you to exclude members of a group list - you have to send a message to the entire group.
• You can call anyone in your MoblMsg contacts list with just a couple clicks.
  You can also respond to a message with a phone call by just clicking a button.
• Many different color combinations to choose from.
  Customize the look of your MoblMsg.
• Many different sound notifications to choose from.
  Choose from 20 different sounds or add your own sounds.
• Message Length Counter shows you how many characters you have left to type before your message will be split and sent as two messages.
  Also, outgoing messages that are split won't be split in the middle of a word.
• Canned Replies.
  Choose from a list of pre programmed replies and save yourself some typing.
