Text Whenever I receive a text it doesnt pop up and say that, it just stays there in my inbox and shows a envolope at the top of the screen

try deleting the messages in your inbox. If the number of messages if over 200, this problem comes up. It fixed the phone I have.

the phone doesnt know where to go when you click that, i dont know why it does that, go to you text messages, then press left or right on the d-pad, near the top left it should tell you what message inbox you're moving to, keep clicking till you get to the work one, you have to remember what name you gave your work account

Does it show signal bars on the screen and are you able to make/receive calls? If not then that is why. AT&T does not guarantee in building service. If you do have signal and it is working other than text, then check your message center number in the device:

From the standby screen, press Menu.
Press Messaging.
Scroll to and select Settings.
Scroll to and select Text Message.
Enter appropriate Message Center Number, then press Done. The message center number that should be there is +13123149810 (and the + sign does need to be in front of it)

well i am not so sure about what would have went wrong..but you can check if you have enabled Screened messages. In that case messages do come but they directly go into the screened messages. 

your inbox could be full. try deleting some text messages.

you will need to contact your mobile provider and explain it to them and have them correct that on their network.

broking screen how can i send text to another phone

I think the best thing to do' is master clear and master resset the phone' but all your massage and file, such as phonebook entries, datebook, media and all the files you have save in your phone will be deleted...

First try to clear your un needed texts, then check your multimedia messages.

have you tried a hard reset? remove the battery, let it sit for a minute and start it up again.
