*#746025625# - [*#sim0clock#]
Looks 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.

*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.

You don't need the warranty-codes any more - you can just scroll through the information like in any other menu. It has the the same data as 81xx and 31xx phones (with "Edit" button for purchase date, and "User data transfer").

Menu:
1: Displays Serial Number.
2: Displays the Month and Year of Manufacture (0997)
3: Displays (if there) the date where the phone was purchased (MMYY) you can here set the Purchasing Date (Warning: You can only do this once - so be careful what you write...)
4: Displays the date of the last repairment - if found (0000)
6: The option is for transferring ALL the telephone data (from the memory) to a "box" so that the technician can fiddle with the phone without worrying about the data stored on it. Stuff stored on the SIM is not transferred, but who delivers their phone with the SIM?

Change Alpha Tag
The alpha tag is the message that is displayed on your phone when in digital coverage. This is normally transmitted by the network, but can be overidden to display a different tag. This is done by creating a tag for a personal/residential zone in the phone, and setting this zone to have the same settings as your normal carrier. So when the phone identifies the network system it believes it is in the personal/residential zone and displays the tag you have programmed.
1) Enter programming mode of the phone by keying *3001#12345#
2) Find out the ID of your operator by entering the NAM1 menu. Note the Home System ID setting. (16387 on Rogers AT&T in Calgary)
3) Scroll to and enter PSID/RSID lists (menu 7)
4) Select P/RSID 1
5) Scroll to PSID/RSID and change the setting to 1
6) Scroll to Connected system ID and change the setting to the ID of your system (eg 16387)
7) Scroll to Alpha Tag and enter the message you would like displayed.
8) Scroll to Operator code (SOC) and enter coed for your provider such as 2050 for Rogers or 2049 for AT&T
9) Scroll to Country code and enter 302 for Rogers or 310 for AT&T
10) Power cycle your phone and hopefully your message will be displayed
Note: This has only been tested in Calgary on the Rogers AT&T network so may not work on other networks.
