You might get more helpful responses if you give a little more detail. For example, which countries in particular.
ATC can be very difficult to understand for a foreigner to these parts, the accents are thick, some Francophone, some Portuguese, some Arabic and some just plain difficult to understand English. In the Non-English speaking parts expect to hear a lot of the local language.
Double check your paperwork before you leave, actually quadruple check it. Carry multiple photocopies of everything including clearances and gen decs.
Some countries here are fairly straightforward, some are so much of a nightmare that unless you need to go, they're not worth the effort. The DRC falls into the latter category, and Uganda falls into the former category, by way of an example.
Nav Aids often don't work, transponders are not a requirement of all areas etc...
Please specify your routing a bit better and people here from the respective countries, with current knowledge will help you better.
Good luck.
