These settings work for the vast majority of Android phones, including Samsung Galaxy phones.
Go to the online configurator here and choose your phone on the list, and follow the instructions to set up your internet. You can also try download the configurator app over wi-fi here.
If the online configurator doesn’t work for you, you can try input the settings manually.
