Connecting with a Samsung Note 4

Is there any information or suggestions on connecting to the network with a Samsung Galaxy Note 4. Just plugging it in did not work. What do I try now?

Thanks

Is it unlocked?

You need to go into the settings and change the APN and enable roaming. I’m not personally familiar with the Note, but here’s some generic instructions: https://content.konekt.io/how-to/connect-hardware/any-device/
