AT&T Mobility

Background
AT&T Mobility LLC, also known as AT&T Wireless and marketed as simply AT&T, is an American telecommunications company. It is a wholly owned subsidiary of AT&T Inc. and provides wireless services in the United States. AT&T Mobility is the third-largest wireless carrier in the United States, with 101.6 million subscribers as of the end of Q1 2022. Originally known as Cingular Wireless (a joint venture between SBC Communications and BellSouth) from 2000 to 2007, the company acquired the old AT&T Wireless in 2004; SBC later acquired the original AT&T and adopted its name. Cingular became wholly owned by AT&T in December 2006 as a result of AT&T's acquisition of BellSouth.

Logo (2006)
Logo:
 * Startup: We see a white background. From the left multiple orange comets with the text "3G" on them form 3D signal bars in blue. The bars spin into the center as another "3G" comet appears moving and changes the bars into the Cingular logo, with the slogan "raising the bar" in blue and signal bars shown next to it.
 * Shutdown: Similar to before, but the Cingular logo is shown at the beginning, and the bars zoom in instead of spinning out. The 3G comet then appears as the text "Good bye" appears at the end.

FX/SFX: 3D computer animation.

Music/Sounds: Availability: Rare; seen on any Cingular-licensed 3G mobile devices from 2006.
 * Startup: Two jet-style whooshing sounds.
 * Shutdown: A different whooshing sound.

Logo (2007-2009)


Logo:
 * Startup: We see a blue bar move horizontally on a black background, bringing up five signal bars. The background then changes into white, as the signal lines expand and curve into the right and then spin out into the forming AT&T logo while the sphere forms around it. "at&t" moves from the left at the bottom.
 * Shutdown: We see the AT&T logo on the white background with the sphere spinning. The five signal bars then spin in quickly at the front as the logo fades out. The background turns black and the bars shrink as a blue turning off effect appears off-center.

FX/SFX: Computer animation.

Music/Sounds: Availability: Uncommon; seen on any AT&T-licensed mobile devices from the period.
 * Startup: A jet-style whooshing sound.
 * Shutdown: Another whooshing sound, this time in the style of a "turning off" effect.

Logo (2007-2010)
Logo: Same as the Cingular 3G startup and shutdown except the Cingular logo is swapped with the AT&T one.

Variant: In some devices the AT&T logo in shrunk (sometimes into an horizontal line) and the text "World Phone" is shown below.

FX/SFX: 3D computer animation.

Music/Sounds: Same as the Cingular 3G startup and shutdown. The single whoosh from the previous logo can be heard in a few devices. Availability: Uncommon; seen on any AT&T-licensed mobile devices from the period.
