Hello, master of data science student at the university of Colorado boulder here… just took 3 courses in networking and would like to improve my privacy and security by moving away from WiFi broadcasting to just Ethernet using cash prepaid sims as a primary source of internet (and Starlink perhaps).

Currently living in Portugal so this gateway will have to support 5G sims from companies such as Vodafone and NOS.

Appreciate any help, tips, advice! As mentioned earlier my primary focus is data science but would love to pivot into networking with a focus on privacy and security. I’m becoming kind of passionate about networking so I would really appreciate some good pointers. Thanks a lot.

So far I’ve been recommended the Teltonika TRB500, link attached.
