I just got my Hologram Nova modem yesterday. Model is:
Hologram Nova US 4G LTE Cat-M1 Cellular USB Modem (R410)
I registered my Hologram SIM last night and set up my account. My dashboard looks good, State says “Live”.
I’m using it with a Raspberry Pi 3+. Install was uneventful and most of the hologram commands return data. Exceptions include “operator” which I assume is a reflection of not being able to connect. I can also connect and issue AT commands and get valid responses. I have a solid blue LED but the red LED never turns on.
From other posts the “Signal strength 99,99” is an indicator of no signal. I used a long extension cord and went out into the street in front of my house and still get the “Signal strength 99,99” message.
What should I try next? I’ve read through the posts and tried the solutions there. Should I try a different antennae? Maybe a different SIM card? Could where I am not have coverage (I’m in suburban San Diego and know people use their cell phones here - my AT&T cellphone works, different network).
