Both English and French are official languages, although French is by far the most understood language (more than 80%). German, the language of the original colonisers, has long since been displaced by French and English. Cameroonian Pidgin English is the lingua franca in the formerly British-administered territories. A mixture of English, French, and Pidgin called FrancAnglais has been gaining popularity in urban centres since the mid-1970s. The government encourages bilingualism in English and French, and as such, official government documents are written in both languages. As part of the initiative to encourage bilingualism in Cameroon, six of the eight universities in the country are entirely bilingual.
In addition to the colonial languages, there are approximately 250 other languages spoken by nearly 20 million Cameroonians. It is because of this that Cameroon is considered one of the most linguistically diverse countries in the world.
To make local and international calls you need to buy a pre-paid SIM card. Check if your cell phone has a compatible GSM standard (Africa/Europe) - if not, in addition to a SIM card you probably need to buy a new phone. "MTN" and "Orange" are two major telephone companies in Cameroon.

It is disrespectful to shake hands with your left hand. Use only your right. If you have something in your right hand or your right hand is dirty or wet, it is polite to extend your wrist for the person to shake with his right hand. Should both of your right hands be occupied, it is polite to touch wrists.
