I made a group that has around 18 contacts. I wanted to send a text message to everyone. When I was prompted to select contacts from the group, it would not let me select more than 10. Anyone know how I can get around that limitation? I have a Samsung Infuse.
Handcent should let you send more than 10 messages at once. It has a nice interface for selecting multiple contacts too. I haven't tested this (I don't want to send 10+ people a random text :) ).
If you are constantly sending group messages you may want to check out some of the Group apps for Android.
