Recently my father bought me a new mobile phone called Nokia C7. I was previously familiar with most of the Nokia phones and knew several useful features. So this phone makes me much user friendly than the previous ones. The other thing is this mobile got the most up-to-date version of software. But when I tried to send a message from it, it just jumps to outbox asking me that resend it. I tried to resend it from outbox but the message wonít send at all instead it keep asking me RESEND. I can receive messages from anyone but unable to send. I have checked my SIM in other mobile. It was fine then what could b the issue in new phone?
