GTIP was a premium-rate SMS question and answer service dedicated to providing computer game-related information. The service was based in the UK, and originally launched in December 2002 alongside the Game Guru television program. The service was run by AlienPants Ltd. Using GTIP and its licensed implementations, mobile phone users could text GTIP with any computer or console game question or cheat request and receive an answer within a few minutes.
GTIP was available for UK mobile phone users using a number of different UK shortcode and keyword combinations in the UK, and in the Republic of Ireland using a shortcode. AlienPants once launched two access keywords in Germany, providing the same computer game cheats service to German customers.
Since the commercial launch of GTIP in January 2003, a number of similar services have launched, including AskMeNow in the US, and 82ASK, Text a Vet and Any Question Answered in the UK.
