If it's Kendari, that's fine. Basically, you have all the daily necessities. It's best to bring your favorite China food, packets or seasonings, and other basic things!
If you stay in Indonesia for a long time, you can get an Indonesian card, which is very cheap! But also can often call back to China, these problems are not big!
I have been to Kendari several times. Although backward, the seafood is not bad! There is a shopping mall! Don't worry!
