V 04.51
26-03-98
NHE-6BM

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 3 different codes on each lock! Then something bad will happen ..therefore be careful!

Bypass the SP lock
With a Nokia 16xx/21xx/31xx/51xx/81xx that are SIM locked to one provider you can bypass the SP lock like this:
1: Insert sim card of different provider.
2: Turn on the phone and press the UP VOLUME key for 3 sec. then release it and the phone says PIN CODE?
3: Press the "C" key.
4: Then Press * and wait until it disappear and appear again, then press * one more time and 04*PIN*PIN*PIN#

The phone now says: PIN CODE CHANGED (or ACCEPTED) and the SIM card is accepted until you restart the phone again. NOTE: On version 5.04 Nokia has removed this option !

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.

Update from 8110 >8110i impossible....
Even though NHE-6 is found on the backside of 8110 too an update from that phone to the 8110i is impossible. The reason is simple. The hardware is different which means that the SW capacity in 8110i is bigger than the 8110.

Original Ringtone
If you want the original ringtone back after you have downloaded one you can send a message to yourself containing the text: //SCKL1581 After some time you will receive a message that you can save, and your original Nokia ringtone is back.

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

Hands Free tip
To continue an existing call when placing the 8110i into the hands free car kit without it dropping the call, press the Memory button just before connecting the cable and placing it in the cradle.

Display extra text in call costs feature tip
If your network operator doesn't offer a call costs service, you can still make use of that function to display some personalized text on the screen of your 8110i. Go to Menu, [5], [7], [1], enter PIN2-code and choose Set. Then type in the limit of the currency units you're using (if the call cost service worked, you would have to type the cost limit of the calls) and choose OK. In this case I typed 8110. Then go to the next sub menu (Menu, [5], [7], [2]), the Show costs in menu. Type in the PIN2 code again and select Currency. Type in the unit price, in this case number 1. Then type the name of the currency - you can use any string of letters and numbers 1-3 characters long. then type 2 letter then to confirm type two names beginning with one of each of the letters. Then press OK to confirm it.

Quick saving while in call tip
Saving numbers to memory during a call If you type a number into your phone during a call, you will lose it when the call ends. To prevent this happening just hold down Memory button -- the number will be saved (with no name) to the next available memory location.
