P.TOM Nokia Phone Hacks

  
Are you a WEBMASTER? P.TOMs NEW Webmaster Tools are now availalbe.

  I have tested all of these tips and trix on my own Nokia 3210 and they (as yet) havn't caused any damage.  However be careful what you do.  I don't want e-mails from you winging about how your phone wont work anymore because you did a code or something.

 

To check the phones Software revision type-

*#0000#

Information you get from the Software revision-

V 05.31

18-02-99

NSE-3

  • 1ST Line  = Software revision
  • 2ND Line = The date of the software release
  • 3RD Line = Phone type

To enter the service menu type-

*#92702689# (*#WAR0ANTY#)

  • Serial number (IMEI)
  • Production date (MM/YY)
  • Purchase date (MM/YY) You can only enter the date once.
  • Date of last repair (0000=No repair)
  • Transfer user data to another Nokia phone via Infra-Red

Clock Stopping (I don't like the sound of this one)

To check weather your SIM Card supports clock stopping type-

Please note this is not for free calls. This feature is to check weather your sim card supports "Clock Stopping". If your sim does support it, your phone will consume less battery power than if it didn't support it.

*#746025625# (*#SIM0CLOCK#)

 

EFR CALL QUALITY

To activate EFR (Enhanced Full Rate) Enter the code-

*3370#

This improves call quality but decreases batterylife by about 5%

To deactivate it, Enter the code-

#3370#

 

NETWORK MONITOR

There is a hidden menu inside your Nokia phone. If you want to activate it, you'll have to re-program some chips inside of your phone.

  1. Check your software version. You can only continue if you have v4.33, v4.73 or v5.24.
  2. Take apart the phone.
  3. De-solder the EEPROM (ATMEL AT 24C64).
  4. Read out the data with an EEPROM programmer and save it to a file (Backup).
  5. If you have v.33 or v4.73, change the address "03B8" from "00" to "FF".
  6. If you have v5.24 then change the address "0378" from "00" to "FF".
  7. Write the new data to the EEPROM and solder it back to the phone,
  8. Power on your phone and you should have "Netmonitor" enabled.

The Network Monitor gives you the following information.

Carrier number

MS RX Level in DBM

Received signal quality

MS TX power level

C1 (Path loss criterion, used for cell selection and reselection). The range is -99 to 99.

RTL (Radio link timeout).

Timeslot

Indication of the transmitter status

Information on the Network parameters.

TMSI (Temporary Mobile Subscriber Identity).

Cell identification (Cell ID, Number of cells being used).

MCC (Mobile country code)

MCN (Mobile network code)

LAC (Location area code)

Ciphering (On/Off)

Hopping (On/Off)

DTX (On/Off)

Discard cell barred information.

CHECK SIM-LOCK (I havn't tried this one)

Note - If you bought your Nokia on UK Vodafone or UK Cellnet you do not need to check this because they both transmit on GSM900, and they don't lock the phones. However if you bought your phone on UK Orange or UK One2one your phone may be blocked. The reason is that they both transmitt on GSM1800. To make a call on GSM1800 you need what is known as a "Dual band" phone. A dual band phone is able to transmit on both GSM900 and GSM1800, so they lock the phones so you can't use it with any other network simcard. If you find that your phone is locked you can try different software to unlock it. (we havn't found one that works yet), or you can ask your service provider who will gladly exchange the 10 digit code for about £35.

This is how to check the status of the 4 different locks. Aslo don't try entering the wrong number, because after 3 times it will block the phone for good.

 

There are 4 different locks on your Nokia phone.

  • COUNTRY-LOCK
  • NETWORK-LOCK
  • PROVIDER-LOCK
  • SIMCARD-LOCK

The code to read out the sim-lock status of your phone is

 

#PW+(MASTERCODE)+(Y)#

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

The master code is a secret code. The code has 10 digits, To read out the sim-lock status you can enter every combination you want!

"Y" Shows the status of the network-lock. Here you can enter a number from "1" to "4". The "4" is for the sim-card lock.

 

SIM-LOCK CHECKS

  • #PW+1234567890+1# = GIVES PROVIDER-LOCK STATUS
  • #PW+1234567890+2# = GIVES NETWORK-LOCK STATUS
  • #PW+1234567890+3# = GIVES COUNTRY-LOCK STATUS
  • #PW+1234567890+4# = GIVES SIM-CARD-LOCK STATUS.

VODAFONE "PAY AS U TALK"

If you are on the Vodafone pay as you talk service within the UK, you can check the balance of your friends "Pay as you talk" phone without them even knowing.

What you need to do is very simple indeed, just dial "1345" from your phone. You will then be asked to enter your telephone number. Enter the number of your friends phone, and it tells you how much credit they have left and how many days are remaining.

Remember that both phones need to be on the Vodafone "Pay as you talk" service.

 

Phones Serial Number

Press *#06# and your phone will tell you it's serial number.  Interesting but doesn't do alot.
