move Home Internet SIM to personal router with external antenna

For anyone who might be reading this 9 months later…. the white router has 4 external small form factor coax antennae ports (assuming 2 for wireless and 2 for wifi).

I haven't used them, but I noticed them and, unfortunately, also noticed the mickey mouse UI. Would be nice to be able to change the internal network ip cidr, disable wireless completely and use passwords with spaces, among other things. Seems like a feature across T-Mobile's UX to not understand that spaces actually increase entropy (it's 2023, not 1998). I worked around this by just hooking up my previous router.

Other than those personal gripes, so far so good relative to cable (surprised at how well it handles gaming and heavy file xfers). I'm still in the trial period so hopefully it's not all downhill from here!
