CompuServe has local dial-up numbers in some African countries, but not in Nigeria. I assumed that phone lines between Nigeria and the U.S. were better than to neighboring states, and most other countries. This appeared to be the case. If you plan to stay for a longer period in an African country, you may therefore want to check if there is a FidoNet node nearby, or the possibility of using the dialup UUCP links in Lesotho, Botswana, Mozambique, Namibia, Swaziland, Zambia, and Zimbabwe. A directory of Internet access in Africa is regularly posted to the alt.internet.services newsgroup.

Most other African countries, however, still have little to offer, but investments seems to be picking up. The United Nation Information Centre.
