Just like on the web version, you can see the delivery status of the messages you have sent to each number. It gives you an opportunity to know what number(s) your message was delivered to.
The Contact Groups helps you organize your contacts better. You can create a group for colleagues, family members etc.
The Online Address Book is where you can:
- Store your new contacts into groups
- Select all or specific contacts from your address book you want to send sms to
- Delete one or more contacts
- Edit your contact's details
