Zanzibar - Do not buy sim card at the airport. They will charge you 25 USD for 4.8GB of data on the Yas network. This data is worth 10000TZS (4 USD). On top of that they won't register the simcard in your name. The simcard is on some anonymous persons name. When u want to recharge, you need their PIN and it's a long story.

Rather buy a simcard from the street vendors. They have the price list with them. They won't rob you. Any forex place also sells. In Nungwe beach there is a simcard and exchange vendor right next to Che bar and Makofi restaurant. Go there instead, they open till late.
