*#06# for checking the IMEI (International Mobile Equipment Identity) 

*#0000# for checking the phones software (SW) - called firmware revision information. 

*#92702689# [*#war0anty#] Warranty code. 
You don't need the warranty-codes any more - you can 
just scroll through the information like in any other menu. It has the 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 repairment - if found (0000) 
6: Transfers ALL phone numbers, pictures, sounds from one phone to another 
(eg. if broken) 8810can also transfer all data via IRport (Confirm Transfer?) 

Software


Type: NSE-6

LATEST Version V 5.00 (29-09-99) 

Older versions:
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 requiet) so don't let him tell you anything else! 



Service Provider 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 upto 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 Provider(???)-Lock status
#pw+1234567890+4# for SimCard-Lock status

(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 US 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



EFR


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 kilobits.(but you take up more space on the network, so they can charge you more) - Talk-time is reduced with about 5%

Half Rate will give you bad soundquality, which gives the serviceprovider the opportunity to have more calls on the network, and you might get a lower charge from them. - Will give you 30% longer talk-time.

Tips and Info 


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.

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. 

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. (trasfer, mute etc.)

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".
