I cannot make phone calls, i can receive them and i can send text messages

call your service provider they will send you a setup message for your mobile including the message center

I would check with sprint to see if your account is up to date. Otherwise, I would suggest going to your settings and see if you can update your phones's prl and profile. go to settings, tap "About phone", Tap "System updates", then tap each option. Good Luck!

for sending text messages :
1.go to your message settings and check the message center number to see if it is correct
2. call to your network operator customer care
3. request the message center number...
4.note it down
5. go to message settings>message center number
6. insert the number which is noted by you and save it


this solves your messaging problem ...
Good luck

Check your message settings, there is a option called Message center number.If the number is incorrect you wont able to send messages while you can receive messages.This Message center number is provided by your service provider.Call your customer care for message center number and enter it to your phone and save in message center number box.Then you should send the messages.

Just Switch off and switch on your mobile. if the problem remain, contact your network operator(customer care).

Call your Cell Phone Service Provider and speak to Tech Support.

Buy a new phone

you may have to check your settings on the nokia- may not have text message 'up-loading'- 'sending' set up. your service may allow 'free' incoming- but not sending!
check your phone settings- may need to go on-line to alter your settings! or find info to set your phone!
good luck!

Check the message center no .. it might me wrong !!! Call ur customer care and verify the message centre no!!
