Use the stock app. U can select up to 50 contacts to send. depends on network etc. after you select contact and click done, phone will give 'coverting to mms' notification and send button will be grayed if you have limitation to mms sending amount. either way, start clicking each contact u have selected and it will show you details of that contact. delete all contacts which show no numbers. email addresses or others just delete and the send button will be clickable again. It converts to mms if you have accidentally selected a contact with facebook or email address only information. Now you will be sending as text. Hope this helps. tc.
