Nokia 5130 Secret Codes

Unlock your Nokia
To unlock your Nokia phone you will need some of the following:
1. Data Cable
2. Unlock Software
3. Extra Help + help Guides

*#06#   for checking the IMEI of the phone
*#0000#    shows the software version. Latest known version:  V. 5.24 NSE-1

*#746025625#   - [*#sim0clock#]
Checks if the sim clock can be stopped. Sim clock stop is a kind of stand-by mode which will save battery time. This code doesn't work with software version 4.59.

*#92702689   - [*#war0anty#]
Warranty code. You don't need the warranty code any more like you did with some earlier phones - instead, now you can scroll through the information like in any other menu. It has the same data as 8100- and 3100-series phones with "Edit" button for purchase date, and "User data transfer".

Menu:

1. Displays the serial number of the phone

2. Displays the month and year of manufacture (e.g. 0997)

3. Displays (if set) the date when the phone was purchased (format: MMYY). You can set the purchasing date here, but be careful what you write - you can do it only once.

4. Displays (if set) the date of the last repair

5. Transfers all phone numbers, pictures and sounds from one phone to another (e.g. if the phone is broken). With 6110 you can transfer all data via the infra-red port.

*3370#   activates the Enchanced Full Rate, after the phone has been turned off. EFR produces better voice quality but also consumes more power.
#3370#   deactivates the EFR, after the phone has been turned off.

*4720#   Activates the Half Rate Codec, after the phone has been turned off. HRC produces poorer voice quality but gives your battery better stand-by times.
#4720#   Deactivates the Half Rate Codec, after the phone has been turned off.

Enhanced Full Rate will give you much better sound quality when you enable it. The new EFR codec uses the ACELP 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. 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 poorer voice 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.
