I have nokia 1600 mobile whenever i send message it show "message sending failed". Can anyone help me.........?

Check the "message center number" it should start with +91....and varies according to sim provider. If someon is using same network copy the number and enter it .It will done

this is a problem with your IMEI number this is liek your phones social security number it basically means your phone has been black listed. there is one way around this but it is highly illegal

dear frnd, restart your phone n enter a valid message centre number...it will work

hi there,
call the customer service of your service provider ( AT&T,Vodafone,Verizon etc)....they will set up message center number on your phone , the one that you have might be incorrect...your mobile operator will send you sim updates that will refresh the settings ....and then you will get the text message options
cheers

try to remove the message center number and then retype it as how it was
Turn your mobile off and turn it back on and check if it works

This works with message sending failed if your account is clear

Check the message center number with your service provider

Try doing a Factory Reset. (PLEASE DO IT ON YOUR OWN RISK - FACTORY RESET WILL DELETE EVERY THING OUT OF YOUR PHONE)

Dial *#7370# now it will ask restore original device settings,yes,it will ask for password its-12345, your phone will restart, all the data on our phone memory will be deleted,and it will be like when you first bought it.

But i don't think so that gonna help you out that much. It seem to be issue with the network. Try using some other Mobile service provider. See if problem still remain their on your mobile.

These kind of error message comes when you have WEAK NETWORK.

check your out outgoing message settings
especially your message center configurations,
you can call your provider and the can send you the settings as a message , then all you got to do is save it

Yes, you have to empty the sent items.. whenever the messaging sent items memory is full we will not be able to send any messages.. this is a dumb concept however it worked for me.. try it and do tell me whether it worked or not...
