Sorta like a computer- Cellphone questionFollow

Since I moved I get almost no signal at home. If I call out or send a text my phone will switch networks and I’ll jump to max signal, then after a few minutes it’ll switch back. This of course does nothing for incoming calls and maybe 1/5 actually get through to me instead of insta voicemail. My phone will not actually tell me what network I’m on. Just what I’m assuming is the FCC carrier ID.

Does anyone know how to find out what carrier = what FCC ID? I’ve spent quite a bit of time trying to phrase a search properly in Google and poking around the FCC website, I’ve come up with nothing.

Crappy 0 – 1 bar if I’m lucky = Sys ID 5269

Full signal I’d love to give money to if I knew who they were = Sys ID 2024

Or maybe I’m looking in the wrong spot. Just viewing settings > network > current network. Phone is a V3 Razr.

Any ideas/suggestions?
