A lot of people have seen this document on the newsgroups, but I did write this, and I'm now quite famous for it at Sprint PCS stores in the area.


This test mode can seriously mess up your phone and is meant only for the Samsung N300, the code is the same to get into the test mode but the codes for the test mode are different in every model phone.

I repeat again (because of someone blaming me for messing up their phone): This test mode can seriously mess up your phone, be careful!

To enter the test mode dial 47*869#1235
After pressing 5, the screen will blank and say TestMode (M)

Here's where the fun begins :)
I have not had time to figure out what everything means here, so please bear with me if something is not exact.

If the screen has something changable on it or reads off constant data, you will need to press # after modifying or viewing the data.(This will type a . instead of a #)

I tried through 200, but nothing else gave a screen.

Once you are done, you need to either take out the battery or press 002 (reboot) to get back to normal operation.

So If you have any idea of what some of these things are, post below, I'd really like to see if someone gets the GPS working, even if its just readable from the debug screen.
It seems that the MSL is the code to get into the phone service menu and the web menu.

To access the service menu type ##(your MSL), and it will take you there.

The service menu explained:

1. Phone #:
    Phone Number  - Your phone number
    MSIN          - Your phone number
2. General:
    ESN          - Same as on the back of the phone
    CAI Revision  - Common Air Interface
    Origination   - Choice between 13k and EVRC (Codecs for calls)
    SCM           - Single Carrier Modulation
    Lock Code     - The lock code to access security menu
    Slot Mode     - Yes or No Choice, No Clue what for
    Slot Index    - Changes how often your phone contacts the tower for updates.
3. NAM
    Home SID      - System ID
    Home NID      - Network ID
    MCC           - Mobile Country Code
    MNC           - Mobile Network Code
    ACCOLC        - Access Overload code - 
                     WARNING! DO NOT SET ABOVE 9, IT IS ILLEGAL!!
                     1-6 Normal use
                     7-9 Doctors and other Emergency personnel 
                     10-15 government only!
    Home SYS Reg  - No Clue
    FSID Reg      - Yes or No choice, Foreign System ID
    FNID Reg      - Yes or No choice, Foreign Network ID

Now for the ##932 menu:
It turns out to be settings for the browser gateway.
The three sub menus are the same
1. Gateway 1
2. Gateway 2
3. Gateway 3

Each of them have this in them:
Gateway (#)
A208. 18.146. 75
B208. 18.146.139
C 0. 0. 0. 0
