Phone rejects Messages

[Mta9896]

I have a trouble with my xperiaL, sometimes it doesn't receive messages, I see the notification that someone has sent amessage but I can't see the message body or phone number, My phone says delete some messages, but I really don't have so many! However I delete, and then NOTHING happens! I can never receive that message, It's driving me crazy!
Somewhere I heared it can be because of full device memory, It's been months that my xperia shows "Storage Space Running out" notification, and I can't move apps to my SDcard, using Link2sd app!
Please help !

This is most likely caused by the phones internal memory being too full. When the internal memory is starting to get full it will no longer receive messages.
Try uninstalling a few apps from Settings -> Apps.
