*#0000# To view Software Version.

*#746025625# [*#sim0clock#]
Checks if the sim clock can be stopped. Sim clock stop is a kind of stand-by mode which will save battery time. This code doesn't work with software version 4.59.

*#92702689# [*#war0anty#]
You don't need the warranty-codes any more - you can just scroll through the information like in any other menu. It has the same data as 81xx and 31xx phones (with "Edit" button for purchase date, and "User data transfer").

Menu:
1: Displays Serial Number.
2: Displays the Month and Year of Manufacture (0997)
3: Displays (if there) the date where the phone was purchased (MMYY) you can here set the Purchasing Date (Warning: You can only do this once - so be careful what you write...)
4: Displays the date of the last repair - if found (0000)
6: Does anyone know if this is for upgrading the phone's EEPROM?? (Transfer user data?)

Software

Type: NSE-6

LASTEST Version: V 5.21 NSM-3 (03-05-00)

Older versions:
V 5.16 NSM-3 (15-02-00)
V 5.00 (29-09-99)
V 4.05 NSE-6 (26-11-98)
V 4.01 NSE-6
V 3.01 NSE-6 (08-07-98) First version!

This is what the Nokia 8810 displays when software code is typed.

V 04.05
26-11-98
NSE-6

First line:
The Software Version (My guess is that this software has been used in previously Nokia-phones, what do you say?!).

Second line:
The date of the SW release.

Third line:
NHE-8 has something to do with the type of phone you are dealing with. Is it GSM 900 (standard), GSM 1800 (DCS1800) or GSM 1900 (PCS1900)? Nokia 2110, 3110, 8110(i) are all NHE types. The only thing that vary is the code after NHE- ("8"). NHE = GSM 900, NHK =GSM 1800 - The number in the end = the model (2110i = 4 etc.) The 5110 and 6110 is called NSE-1 and NSE-3...this may be because it supports EFR (?)

Software update, how?
I have been asked a lot about how to update the software in your cell phones. The easiest thing to do is to go to the nearest Nokia dealer and make him do it for you. Just remember that it is supposed to be free (a receipt is required) so don't let him tell you anything else!

Service Prover Lock
The service provider (SP) lock is used to lock the cell phone to the SP's SIM card. Once the cell phone is locked to a specific operator, if one inserts a SIM card from a different operator the phone will refuse to accept it! The cell phone will however accept another SIM card from the same operator.

All Nokia phones (2110 and newer) have four different SIM locks which can be used to lock the phone for up to 4 different providers. But most phones with restriction only have one lock activated. ( lock 1)

The main code used in Nokia phones is:
#pw+(master code)+Y#
This code is able to check, activate or remove Sim card restriction (SP-lock).
Use the * key to get the p, + and w chars.
'Y' has to be 1,2,3 or 4 - depending of what lock you what to deal with.

#pw+1234567890+1# for Provider-Lock status
#pw+1234567890+2# for Network-Lock status
#pw+1234567890+3# for Country-Lock status
#pw+1234567890+4# for SimCard-Lock status

# = DOUBLE-CROSS
W = PRESS "*" THREE TIMES
P = PRESS "*" FOUR TIMES
+ = PRESS "*" TWO TIMES
MASTERCODE = 1234567890
Y = NUMBER 1 TO 4

(master code) is a 10 digit code, based on the phones IMEI number.
(I can NOT give you the master code - SO DON'T ASK ME FOR IT !!!!!!!)

Eg. To remove restriction on lock 1 type following code:
#pw+(master code)+1#
If you just want to check your phone use 10 random numbers Eg. 1234567890 as the (master code)
eg. To check if phone if restricted on lock 1 type the following code:
#pw+1234567890+1#

Please NOTE that these codes could be used with care! A user told me that it's only possible to type in about 5 different codes on each lock! Then something bad will happen ..therefore be careful!

In most Countries Nokia has denied to lock this phone to a Service Provider

Enhanced Full Rate Codec (EFR):
On: Enter *3370# and EFR will be activated after a reboot of the phone ( consumes more power )
Off: Enter #3370# and EFR will be switched off after a reboot of the phone.

Half Rate Codec:
This function is NOT available on 8810

Enhanced Full Rate will give you much better sound quality when you enable it. The new Enhanced Full Rate CODEC adopted by GSM uses the ASELP (AlgebraicCode Excitation Linear Prediction) compression technology. This technology allows for much great voice quality in the same number of bits as the older Full Rate CODEC. The older technology was called LPC-RPE (Linear Prediction Coding with Regular Pulse Excitation). Both operate at 13 kilo bits.(but you take up more space on the network, so they can charge you more) - Talk-time is reduced with about 5%

The 54# Tip:
Type 1#, 2#........54# on the keypad (when you're not in the menu) to get the phone number used for with this key when speed dialing.

Power Button Tip:
If you press the button for a short moment, the menu with the profiles is shown on the display. If you press one more time, the mobile turns itself off. You can use the up and down cursor keys to scroll and enable a different alert setting.

Quick SMS Typing
When typing SMS messages, you have to wait some seconds before you can type the next letter if it is in the same button than the previous one. For example try to write the word "letter", you have to wait before you can enter the second "t".. A much faster solution is to press the # button twice and then the letter "t" or just press the down button once and continue to use the same letter key.

Free SMS Tip
1st Way:
1. turn our phone off.
2. turn it on and enter your pin.
3. enter *#746025625# 4. now "SIM CLOCK STOP ALLOWED" will be displayed.
now you can send sms for free. if you turn your phone off and later on you have to reenter this code!!!
In some Networks it doesn't work!!!
2nd Way:
Set Menu 4-6-4 or 4-3-3 on User group 666 (work with German Networks)

What's a Business Card?
A business card is a special SMS message which is composed as following: //SCKE2 BEGIN:VCARD N:name TEL:number END:VCARD

Call Menu
(In a call) you can press and hold down the menu button for 3 sec. and a menu appears. (transfer, mute etc.)
