Loved it at first--especially the feature where I can sync it to send and receive messages from my computer. Lately though I noticed group messages buffer and I can't get them using just my mobile connection (i.e. I have to be connected to wi-fi). I've tried everything but no luck. I do get notified I have a message waiting to download but it won't download the actual text unless I connect to wi-fi. I may have to abandon this app for some other messaging app.
