here are a few commands that did work.

You do not need to run any command manually.
What LTE band(s) are you going to use?

Yes make sure that the modem you have will cover at least one of the bands that T-Mobile uses. These modems were typically built in regional versions with different band sets. The logs look like no signal at all has been received from a tower yet.

Also, although I don't think it has reached this stage of connecting yet, T-Mobile requires setting the modem IP type to IPv6. They don't make native IPv4 connections.

Edit: DW5814E appears to also be known as Telit LN930-AP which is definitely not going to work with T-Mobile USA. This modem was intended for use in Japan.

have you tried sending AT commands to the modem? That's how I usually set up my EP06-E.

I had it working once before with either a Visible or MINT mobile chip. Plus it recognises the Tmobile tower and even gets the phone number.

this is the modem
https://amzn.to/3xipbXN

most say its a EM7455 by sierra

i was under the impression the modem would choose the best one

now in all of this, even putting modem in an old dell to install firmware, I've yet to figure out how to do that...

opkg update
opkg install socat
socat - /dev/ttyUSB2,crnl

if ttyUSB2 does not work, try 0,1,3...
then follow AT commands manual for your module

how far up the number list do I go?

Configuring socat.
root@bpir3jmyntrncom:~# socat - /dev/ttyUSB2,crnl
root@bpir3jmyntrncom:~# socat - /dev/ttyUSB0,crnl
root@bpir3jmyntrncom:~# socat - /dev/ttyUSB1,crnl
root@bpir3jmyntrncom:~# socat - /dev/ttyUSB3,crnl
root@bpir3jmyntrncom:~# socat - /dev/ttyUSB4,crnl
root@bpir3jmyntrncom:~# socat - /dev/ttyUSB5,crnl
root@bpir3jmyntrncom:~#

It has nothing to do with Sierra.
DW5814e is Telit LN930-AP where AP stands for Asia Pacific.
So, what LTE band(s) are you going to use?
