I have a Nokia 3595 from at&t. But know I want to use the GSM 850 and is not working. Do I have to use codes to change from 1900 to 850? The manual says that is a dual band, working on both bands.
What is happening is that my cell recognizes the chip, but does not receive any signal. Can be a problem of transmitting power?
If anybody can help me, I would be thankful.
