Manually Selecting Contacts for Deleting, Adding to Different Groups or Mass SMS
In the Contact List there is a hidden menu. From the hidden menu you can move contacts around to different Contact Groups lists, delete them, or manually select them from the page to send mass SMS to.
Once you select any number of contacts from the Contact List this hidden menu will pop up for these actions. If there is more than 1 page in your contact list the selected contacts will reset and not be selected when you click back and forth through pages.
