Thanks.
I think anyone in USA using Hologram on T-Mobile would benefit from this. I just worry I break something else.

I’ve been fighting a problem for the past few months with registration getting denied on T-Mobile in USA using Hologram and our new 4G SIM7600G modem. Without cellular connectivity at home, it hasn’t been easy to recreate this, but I found a solution: I've been seeing intermittent netreg errors lately; I've booted this version on a couple of my modules...
