The information on this page covers secrets and field test functions on both Nokia 6185 and 6188 models plus the Nokia 5185/85i. Secrets Change the provider's name to your own welcome message on startup: Menu-1-3 Change the provider's name on the screen: Enter *3001#12345#, then select NAM1, ALPHA TAG, and enter in your own text string. Power off to get out of this menu Quickly switch profiles: Hit POWER button briefly to select Keyguard: Hold down END key for 2 seconds OR Menu + '*' OR Menu + '9' Phone lock to prevent unauthorized use: Menu-4-3-2-1, ON, Power off to engage Setting Speed Dial: NAMES Softkey, 1-TOUCH DIALING, Pick name out of phone book Software version: *#837# or *#VER# or *#9999# Serial / ESN: *#92772689# or *#WARRANTY# Phone reset? *#SLOT1# or *#SLOT2# (changes value on screen 46, line 3 -- Thanks Andrew S). Also see this page for a more detailed description of the slot cycles. Phone programming *#639# (do only if you have programming codes -- Thanks Peter Hartmann) How do I get the date to show up on my 6185/8 like your phone above? Earlier firmware versions of the 6185/8 do not show the date on the screen. Contact your service provider and ask for a firmware upgrade of your phone (this is free service -- no authorized dealer that can upgrade firmware should charge you to do this). How do I use my Sprint 6185 on Verizon (or Bell, Telus, etc)? You need to have an unlocked phone to switch providers. See the general Nokia secrets page under SP-lock status. If your phone is locked then you may try unlocking it with various software programs available on the internet to generate unlocking codes (enter any codes generated from this programs at your own risk), attempt to get the unlocking code from the original service provider, or play around with the firmware. In general, codes are not easily obtainable and most people just buy a new handset to use with the new provider. Please don't email me asking for names of software, how to override the firmware, or the service programming code (I don't have the answers to these questions, but there are people that have successfully done this that lurk in newsgroups or cellular stores).

Forcing 800 MHz AMPS network (analog) on the 6185/8: In some areas EVRC may not be functional yet and you may be able to force analog mode on this phone by entering *#EVRC# and enabling the Enhanced Variable Rate Codec. If EVRC is not supported then the 6188 will default to analog mode. Once you are done using analog mode, disable the EVRC by repeating the above process to return to digital mode. This trick may also work on some 6185 models that do not have an analog roaming option in the Network settings. If your service provider also offers analog or AMPS then there might be a force analog feature available from the menu.

Forcing other 800 and 1900 MHz CDMA networks from the 6185/8: If your service provider is using 1900 MHz CDMA (e.g., Bell Mobility, Telus Mobility, Sprint PCS, Verizon, Wireless North, etc...), then you may be able to force your 6185/8 into 800 CDMA mode by entering *22800 or *22801 and hitting TALK. If you successfully contact a 800 CDMA network (e.g., Telus Mobility, MT&T Mobility, Verizon), you will hear a message from that network. Telus' message is: 'You've reached the customer service centre at Telus Mobility...'. Hit 3 then 9 to listen to different rate plans from Telus which will give you a few minutes of looking through all the different test mode screens. Note that this procedure may take a few times to work -- you'll get assaulted with a tone if it doesn't. The Nokia 6185/8 allows you to track other CDMA providers' offset information and more.
This is how the *2280x searches for providers:
*22800 - 800 CDMA, Band A
*22801 - 800 CDMA, Band B
*22802 - 1900 CDMA, Band A
*22803 - 1900 CDMA, Band B
*22804 - 1900 CDMA, Band C
*22805 - 1900 CDMA, Band D
*22806 - 1900 CDMA, Band E
*22807 - 1900 CDMA, Band F
Thanks to Peter Harren for providing information on the *2280x forcing

Field Test
The test mode display is activated through the test mode command: *3001#12345#. Once you enter this command, you are given a list of options, including 'Field Test'. Select Field Test and then hit 'Enabled'. You must power down the phone and power it up again to get out of the test mode menu. The test mode screens may vary somewhat between different firmware versions and providers.
Once you power up the phone you are given a new menu choice at location 10 called 'Field Test'. There are several different test mode screens. Type in a test number to get the screen listed below. Alternatively you may use the arrow buttons to move between the 199 different field test screens. Entering test number '0' will disable the test mode, but will still allow you to access the test menu.
If you are using the field test mode and are unsure what the screens mean then hold down the # key for about four seconds to get a brief description of the screen. Repeat holding the # key to return to the test mode values. Thanks to L. Tee for this tip
If you would like to see what is behind the test mode screen then keyguard the phone, wait until the 'press unlock and then *' screen disappears, and then press one of the numeric keys to see the regular screen. Thanks to L. Tee for this tip
Note: If you make or receive calls while in test mode, you may not be able to change the speaker volume. To turn off the field test mode you can select field test '0' or enter a few digits and then clear these digits.
