Who uses +237
+237 is the country code for Cameroon, listed on this page as the single country it serves. The country's official name is the Republic of Cameroon and its ISO code is CM. Anyone with a Cameroonian mobile or fixed number is reached through this code, and the demonym for the people who use it is Cameroonian.
Where Cameroon is and how it runs
Cameroon sits in Africa, within the Middle Africa subregion. Its capital is Yaoundé. English and French are the languages of the country, and the currency is the Central African CFA franc. Local time follows the Africa/Lagos time zone at UTC+01:00.
Cameroon mobile numbers appear in the international format +237 6 71 23 45 67. This is the example format to follow when a number is written or stored with its country code. The +237 prefix replaces the local dialling form when a number is used from outside the country or shared in writing.
Calling and messaging over the internet
A +237 number can be called or messaged over the internet using a data connection. The call or message travels over the data link rather than the mobile voice network, so a working connection is the requirement on the sender's side. This approach keeps the cost of reaching a Cameroonian number low compared with conventional international routes, and it works from any location where data is available.
Slashtel sends prepaid mobile top-ups to two Cameroon operators: MTN and Orange. You can top up a Cameroon number for either operator. Top-ups add prepaid credit to the recipient's mobile account, which supports calls and messages on that number.
