I tried to set up call forward on Android phone. Aftger inputting the forward phone number, the message says:Call Setting ErrorUnexpected response from network How can I fix this problem? Thanks
I tried the normal way. It didn't work. Then I tried the following method:Dial *21*, followed by the 10-digit number you want your calls forwarded to, thenthe error message is:Call forwarding unconditional coneection problem or invalid MMI code.
