Enhanced Full Rate Codec (EFR) :

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 (Algebraic Code Excitation Linear Prediction) compression technology. This technology allows for much greater 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). Also this improves call quality but decreases battery life by about 5%.

*3370#
EFR will be activated after a reboot of the phone (consumes more power).

#3370#
EFR will be switched off after a reboot of the phone.

Half Rate Codec (HR):

Half Rate will give you bad sound quality, which gives the service provider 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).

*4720#
Half Rate coded will be activated after a reboot of the phone (better standby time).

#4720#
Half Rate coded will be de-activated after a reboot of the phone.

Clock Stopping:

*#746025625#

To check if the Sim -Clock can be Stopped. This option is dependant on your service provider network. (Sim -clock-stop is a kind of standby mode which will save battery time).

CHECK SIM-LOCK:

Note - If you bought your Nokia on UK Vodafone or UK Cell net 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 transmit 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 or you can ask your service provider who will gladly exchange the 10 digit code for a price.

This is how to check the status of the 4 different locks. Also 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)#

MASTERCODE = 1234567890
Y = NUMBER 1 TO 4

The master code is a secret code. The code has 10 digits. It must be computed with a program e.g. SmartDCT4Calc and/or DCT 4 code Calculator from IMEI etc.

"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

Reset Wallet Code:

*#7370925538#

This will factory reset the wallet, and you will have to give it another code. Please type the code in while on the stand by screen. Note that you will lose all previously saved data in your wallet.

Restore Factory Settings:

*#7780#
Your default lock code is 12345

Soft Format:

*#7370#
Your default lock code is 12345
Also make sure your battery is at least 75% full.
