Whenever I get a group text on my Samsung Galaxy S3 on Verizon, all I get is a box saying "Download". When I hit it it changes to "Downloading". Nothing ever downloads, in fact it says "downloading" for about 5 minutes then just stops. I can not read the message or reply. I also can not send a group message, when I try I get a message "No network connection Mobile Data is disabled. This message will be sent when mobile data is enabled". i am connected to Wi-fi and can go to the web, download apps,play games,check email. Any ideas? The phone has been updated. I tried the basic tech support answer - Turn it off and turn it on again. Still doesn't work. Thanks for any help you can give!!
