I talked to NTT staff about having a box at home that looks like it would be for Hikari internet, but they checked and it seems like construction would be necessary and they don't know why this box exists. https://imgur.com/a/a3M8dUZ
We will be living here for only about 8-12 months so we don't really wanna go through the hassle of Installing something new.
Do you guys have any idea what this box might be? Also do any of you have experience with SIM card WiFi routers? Are they suitable for work and some gaming?
