    Hi, i need to unlock my Nokia:

    Model: Nokia 1600
    Type: RH-64
    IMEI: 351898011113802
    Country: Netherlands
    Provider: Vodafone

    I already tried the first of the following codes and I received a "Phone restriction off" message:

    #pw+417667033613607+1#
    #pw+203005524267346+2#
    #pw+432887055165723+3#
    #pw+118584035762224+4#
    #pw+252485273121423+5#
    #pw+806401420571345+6#
    #pw+796790612534333+7#

    Oddly, the phone doesn't accept any SIMs (besides the original vodafone one).

    Can you help me? Thanks.

    check to see if there is any securiy settings on the phone

    although the phone is unlocked if the security settings are on for the simm card it wont work unless u put in the security code to unlock the phone

    if u understand what i'm trying to say
    the default code is 12345
    if u changed your security code then u will need to put in your security code

    also check to see if the phone can operate on the frequency of the carrier u would like to use

    having an unlocked phone and not being able to use it on the frequency of your desired mobile operator becuase your phone doesnt support the frequency makes your phone ---a paper weight so to speak

    hit me back with some feed back

    Hi, I'm back after a few tests:

    MCCRASH, I tried many SIMs: Telfort (NL), KPN (NL) and TIM (IT) but all with the same "SIM not valid" grim result...

    Skylinegt, I can't change any setting (so neither the security ones) as there is no menu appearing. The only command I see is DEMO, and the sad message as above. I understand that many phones can set an additional security level accessible by access code 12345, but it doesn't seem my case (I should be asked to input the code when switching on, shouldn't I?).

    I suppose that at least the 2 sims from dutch operators should work on the normal GSM european frequency bands (900 and 1800), being the 1600 compatible with 2G Networks (GSM 900/1800).
    I appreciate your quick help guys, but i'm still (b)locked. Any further ideas?
