I live in Tanzania, of recent my n 6600 wont send messages with either chip I use (I have two), the messages go to outbox and in a shortwhile fail. However, when I insert the chip in another phone the messages are sent normally. I am told I need codes to unlock this problem:con? ..Can anyone help me?

See if You have the network sttings well. Go to a Nokia Site - Support Pages - send the settings to You by SMS.

Read some other threads and tried formating it. It has worked well but the bad thing is I forgot to back up my contacts!!!!!!:frown: :frown: :frown: :frown:

First go to messaging,klik option then choose setting after that go to text messageThen identify the message center in use and the message center according what type telephon network that are u using.:)
