[3] This earned him a transfer to French club Le Havre AC but he was unable to break into the first team, and remained a reserve for the duration of his spell, also being loaned to AS Saint-Étienne and also failing to gain any playing time there.

Kameni almost joined Premier League's Wolverhampton Wanderers on a season-long loan for the 2003–04 season, but the deal collapsed after he was not granted a United Kingdom work permit.

[5] 20-year-old Kameni signed with Spanish side RCD Espanyol in July 2004 for US$600,000,[6] and became first choice in his second year, winning the Copa del Rey as backup to Gorka Iraizoz, who started in La Liga.

[12] On 13 January 2012 he moved to Málaga CF,[13] making his league debut on 25 March after replacing injured Willy Caballero during the first half of a 2–1 away win against his former team, and keeping a clean sheet during his time on the pitch.

[15] The following matchday, he became the first club goalkeeper to provide an assist in the Spanish top flight, as Charles scored the second of his three goals in the 3–1 home victory over Real Sociedad.

However, he ended up on the bench as coach Paul Le Guen preferred Souleymanou Hamidou over him, and the national side was the first team to be eliminated from the tournament after losing all three group matches.

[31][32] On 27 October 2015, more than two years after being left out of consideration for selection for "trying to orchestrate disorder", Kameni was called by new manager Volker Finke for a game against Niger for the 2018 World Cup qualifiers.
