The given below Nokia codes might not work on some Nokia Mobile Phones but the codes are universal codes. As it is told that, the codes activate not only Half Rate Codec but activate Enhanced Full Rate Codec as well. The codes are all about numbers, hash and asterisk. When you give the *3370#, then your phone will gives the best sound quality then before but reduces the talk time by approximately 5% and the same code will deactivate the above told function. *#4720# Activate Half Rate Codec i.e. this code gives you a lower quality sound but you are supposed to yield approximately 30% more talk time and deactivate the function by same code. *#0000# displays the version of your Nokia set, first software version and after that the released date of the software and lastly it shows the compression type. *#9999# is used instead of *#0000#, in case if the code *#0000# doesn’t work. *#06# is used to check the International Mobile Equipment Identity (IMEI) Number. Simultaneously, for Provider Lock Status, Network Lock Status, Country Lock Status and SIM Card Lock Status, the code #pw+1234567890+1/2/3 and 4# is used respectively and in order to get the ‘p,w,’ and ‘+’ symbol, use the button ‘*’. *#21# lets you check the number that “all calls” are diverted to. In case of Vodafone, *#147# this code allows you see who called you last and *#147# displays the last call.
These are some of the useful codes that we didn’t know earlier. And, amazingly, there are many other codes for Nokia, which may take a day for me to upload here. So, if you are interested to know your query about the other codes, then we can talk about it through the comment button.
