Some of the quirky codes to type into the dialler on mobile phones (smart and non-smart) that I’ve found or had vendors tell me about. I first started using these with Nokia phones.
*#06# Display IMEI
*#100# Show Phone Number
*#67# Show call forwarding
*43# and #43# to activate or deactivate call waiting
*#0000# Firmware version (or try *#51×0# or *#9999#)
*#92772689# View Serial No., Date Made, Programming Date, Repaired
*#06# IMEI (International Mobile Equipment Identity) Code:
*3370# to activate Enhanced Full Rate (EFR). Makes calls sound better, but decreases battery life by about 5%.
3370# to deactivate EFR
*4720# to activate Half Rate Mode (HFR). Decreases call quality but increases battery life by about 30%.
4270# to deactivate HFR.
Default Security Code: 12345
#92702689# [#war0anty#] Warranty Code asks warranty code. You can then type a number of codes…
6232 – Display date of manufacture
7332 – Display date of last repair
7832 – Display purchasing date
9268 – Display serial number
37832 – Set purchasing date to MMYY
87267 – Confirm Transfer, Related to firmware upgrades
746025625# says SIM CLOCK STOP ALLOWED or similar, depending on your SIM card. Newer SIMs have a feature called ‘clock stopping’ that allows the phone to save energy – it is a kind of sleep mode for SIM cards. Not all versions of software support this. You cannot turn the SIM clock on and off, the phone will do it automatically if the SIM supports clock stopping. For more information read this archive from the Nokia Nerds mailing list.
