The "TW", in "TW@", stands for "Totally Wireless", as can be seen outside some TW@ Internet Cafés. This phrase is a take on "Totally where it's at."
"TW@" is a reference to twat, which is a British slang term for "vagina", often also used in offensive manner to imply someone is an "idiot".
In GTA III, the TW@ café (in Torrington/Newport) has no doors and is only accessible by breaking any of the windows. However, this rendition is filled with random pedestrians that will walk around aimlessly, bumping into the windows trying to get out due to the lack of doors. Two monitors inside the café show screenshots from Grand Theft Auto 1 and Grand Theft Auto 2. A stunt jump can be completed inside the café through the staircase.
In GTA Liberty City Stories, due to the earlier setting than GTA III, the TW@ café is only just being constructed. Its posters state - "Come and see the grand opening of TW@", yet another obscene reference to the British meaning of the word twat.
In GTA IV, the TW@ Internet Cafés have gained notable popularity and at least one can be found on every major island. TW@ cafés can be used to browse the in-game websites and are accessible from the start of the game. The internet is introduced to the player in the mission Logging On where the player has to set up an Eyefind e-mail account. It costs $1 to use the computer. The stores can be robbed by simply opening the cash register and taking from $9 to $199, but doing so will usually result in a one star wanted level. But this can be avoided, if the player crouches behind the counter of the Snack Shop, out of sight and then opens the cash register, no one will notice and will act as if nothing has happened.
In Episodes From Liberty City, the computers have new wallpapers: in The Ballad of Gay Tony, a dark background with a silhouette of the Liberty City skyline and the phrase "I ♥ LC," which is a reference to the first mission in the game. In The Lost and the Damned, the Lost MC safehouse computer has a wallpaper resembling one of the default Windows backgrounds. The radio station playing inside the internet cafés in Grand Theft Auto IV is The Journey. In Episodes from Liberty City, this is changed to Self-Actualization FM.
In GTA V, there are no accessible TW@s as internet can be accessed from a phone or at one of the main character's houses, but does still appear as random establishments on the streets of Los Santos, primarily in Little Seoul. The limited appearance in GTA V reflects the decline in this type of business that came with the prevalence of mobile device internet access by 2013.
Grand Theft Auto III
Grand Theft Auto: Liberty City Stories
The same place as in GTA III. The store is under construction.
Grand Theft Auto IV
There is an internet café on each of the three main islands.
Grand Theft Auto V
Wan Ka Internet Cafe
One of the locations on Vespucci Boulevard was seen in a promotional screenshot with the name Wan Ka Internet Café (왕카인터넷) in Grand Theft Auto V. This name was replaced with Totally Wireless (Tw@) once the game was released.
The words Wan Ka is a reference to the British term 'wanker'; a person who enjoys constant masturbation, or is considered an idiot. Wan Ka does not exist in the Korean language, and is instead the Mandarin Chinese term for an internet café.
- TW@ internet cafés do not appear in Grand Theft Auto: Vice City, Grand Theft Auto: Vice City Stories or Grand Theft Auto: San Andreas, reflecting the fact that Internet cafés did not exist in the 1980s/early 1990s time frames of those games. Although, in San Andreas, a pedestrian can be heard saying; "This internet is crap, it'll never take off." He can be heard saying this when bumped into; "Go to TW@." Pronouncing it like 'T.W.A.'. This may indicate also that TW@ Internet Cafe was founded in or around 1992.
- At all TW@ internet cafés in GTA IV, the photocopier behind the cashier's desk is a Kakagawa Power Ultra 3000 Pro. The screen of the photocopier also has an easter egg as the screen reads: ERROR Unleash ninja guru lol.
- TW@ computers and all of the other computers in the game, have the same cursor used in Microsoft Windows, from Windows 3.1 to Windows XP, which may indicate that the operating system used in the game is a Windows operating system. There is more proof of this, as the Lost MC Clubhouse has a computer with a wallpaper resembling a default windows background.
- Originally, TW@ was able to sell food and had a larger selection of staff.
