check its not your phone alerts

Usually this means the text Inbox/Outbox is full, once you delete them it should go away. You can have 500 text messages total on your reserved memory. Once you reach 500 you get the flashing mail icon and it saves texts to the smartchip (which holds 30 extra texts) and you won't be able to send a normal sms message, it will make you send a mms slide. Delete your messages, and that should fix it. Hope this helps, if you have anymore questions feel free to ask :)

Call your cell phone provider (AT&T, Verizon etc) with a different phone than your cell and ask them if they have disabled your SIM Card.

try to unlock the contact. try going to it and cycle through the options

replace it

i am told by a boost rep, that the phone takes a few days to find out who peoples networks are, if you notice, people who text u from boost show up in your "Inbox" with there number and contact name shown, with the top left button as reply, but if any anbody who is not on boost texts you, their text will go in a "SMS" box at the  bottom of your message center screen , with no number, contact name, or reply option, boost said this will fix itself in a matter of time.

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