Sammy Adjei was transferred from Accra-based Ghanaian club Hearts of Oak to Club Africain for a reported $150,000 on 15 September 2005. On 29 November 2008, he returned to Accra Hearts of Oak SC for a second spell with the club. He agreed to return to Accra Hearts Of Oak SC on a one-year contract in order to convince then national team coach Milovan Rajevac to include him in the national side.
Adjei was the first-choice goalkeeper for the national side until 2006, when Richard Kingson rose to prominence. Adjei was named in Ghana's squad for the 2006 African Cup of Nations in Egypt and 2006 World Cup squad on 13 May 2006. Adjei made one appearance on the tournament, as a substitute, when the first choice goalkeeper Richard Kingson was taken off with an injury.
On 24 March 2007, Adjei manned the post for Ghana against Austria in a FIFA International friendly in Graz. He was however injured in a collision with an Austrian striker in the first half and was taken to the hospital. Richard Kingson was brought on to replace him. Adjei was again called up to join the Ghanaian national team in the 2008 Africa Cup of Nations as the second choice goal keeper, after which he retired from international football. However he received a recall for Ghana's Africa Cup of Nations qualifying match against Congo.
