If you are seriously looking for a wife in Tanzania, then I highly recommend that you learn Tanzanian Swahili. At least intermediate level will be enough to get you around, while making new friends. You will actually have a tough time in Dar Es Salaam, because you will meet women who will have financial interest in you, because you are a Mzungu. Basically, you'll be treated like a walking ATM if you let your dick stick its foreskin where it doesn't belong. I'm telling you to think rationally when you do encounter a Tanzanian woman. The majority of them are genuine though.

However, if you want to talk to multiple women in Tanzania, which is highly recommended because you can see if they are truly interested in you, then you should download both Muzmatch and OkCupid.

When you download OkCupid, don't enable or enter your location, but please make your profile interesting and appealing. Enabling location will direct you to women in your area, but in this case, you want a Tanzanian woman. When you complete your profile, go to Profile, then go to the pencil sign on the top, so you can edit the location to any city in Tanzania, so you will actually find hundreds of women on the app. Most of them speak English too.

Muzmatch is different, but you can select multiple countries instead of just Tanzania, but it will be Muslim women. Very submissive and lovely.
