MoblMsg allows you to create groups from your Windows Mobile contacts in order to send the same message to all of the contacts you've defined in this group.
There are times when you need to get a text message out to lots of people at once, and it can be oh-so irritating having to type the details several times and send it to umpteen different numbers. MoblMsg solves this problem in a flash.
MoblMsg is installed very quickly through your desktop PC via ActiveSync and leaves a very small footprint, so it won't put any kind of strain on your device's resources. The user interface is a little ugly though, and the buttons are clunky and irregular in size. Nevertheless, MobMsg makes it simple to create new groups and add recipients to these groups in the main window, using the arrow buttons. There are no options for editing contacts in MoblMsg, which I felt was a bit of a shame.
Once the groups are connected you can write a message and send it to everyone in the group with the click of a button. MoblMsg stores all of your sent messages so you can go back at any time and check what you've written and when.
There are definitely better designed groups SMS tools out there, but nevertheless MoblMsg does provide a simple and functional way of creating group messaging lists.
