Hello folks, most of the times, I'm unable to send SMS using my Nokia 6600. It gives me an error saying "Message Failed". And when I click details, it says "General : Memory Full. Close some applications & try again"

I have checked using Devman. There are no applications running in the background. I have tried formatting my cell, restarting it etc. But it doesn't help. Am able to send SMS immediately after restarting the cell, but after about 5 min, I'm unable to send any SMS. It gives the error mentioned above. Can anyone please help?

format the phone using *+3+call key+power key just hold power button when the formatting pop up release pressing power switch or *#7370# to format your phone too...its normal problem in nokia phone
