In addition to the basic messaging features, GroupMe offers a nice selection of extended options, allowing you to use it for more than simple text messaging.
For a start off, there is a conference calling feature, accessed when you create a group. This isn’t limited to GroupMe users either, and is activated in the group view by tapping the Call button. Clearly this is a great feature, although note that it will use your call credit to contact the phone number hosting your conference call.
Another handy feature is photo sharing, available by adding an image (or any file) as an attachment to a message. This enables you to instantly share a photo that you might have just snapped with your group of friends, although remember that they will also be able to share the same image with other friends…
SMS text messaging is also available, a useful option for when mobile Internet connectivity is restricted by location or perhaps weather conditions. You can also check the location of the contact you are currently communicating with, useful for if you want to arrange a place to meet.
