The NET light is flashing every 800ms which means that the network could not be found. Do I need to set up the APN with hologram in order to use the botletics board?
This is the output I'm getting

Make sure you have a LiPo battery connected, with proper polarity (red wire on the left side of the connector, marked with a "+" on the board).

I had a LiPo battery connected when I tried it. Is there anything else I can try?

Please check that the solder joints are solidly making connection on pins 10 and 11. You said the blue network status LED is flashing, which means the module is powered on, so it seems to be a connection issue.

If the board is powered on without being connected to the Arduino, can the blue (NET) light flash every 3 sec rather than 800ms, showing that a network has been found, or does it have to be connected to the Arduino.

I tried putting the Hologram SIM into my iPhone 13 and after some time, a Bell network was recognized, but I was not able to make phone calls or use the data so I am wondering if the SIM card is not set up correctly.

Yes, the board can be powered on without being connected to an Arduino, but always make sure you have the LiPo battery connected.
Sounds like you're maybe in Canada using Bell's LTE CAT-M network? LTE CAT-M won't work normally on a normal phone. With the LTE_Demo sketch you can check the network details with 'n' and '1' commands.

Okay thank you for the clarification. I had to LiPo battery connected all throughout my testing. Before the code is pushed to the board, and the hologram SIM is placed inside of the SIM7000A, will the SIM7000A connect to the network (the NET light flashes every 3 sec rather than 800ms)?
I am trying to figure out if the board does not recognize the SIM card, or if there is some other problem
Thanks!

It may connect temporarily on its own even before the code is pushed, but it probably won't stay connected, because some of the code sets the configuration parameters for network connection (like APN, etc.)

Okay makes sense. Usually when I set it up, I turn it on and the board is on and the NET light is flashing every 800ms, and when I try to push the code, that is when I get this output.

Yea only thing that could be wrong is the physical solder or header pin connections between the shield and Arduino. Check pins 6, 10, 11, GND, and 5V specifically.

I have finally gotten it working! Thank you for your help. I have another question as to the format of how to send messages to another mobile device.
This is the output I am getting:
] Enable NTP time sync (SIM800/808/70X0)
[t] Get network time
[G] Enable cellular data
[g] Disable cellular data
[l] Query GSMLOC (2G)
[w] Read webpage
[W] Post to website
[2] Post to dweet.io - 2G / LTE CAT-M / NB-IoT
[3] Post to dweet.io - 3G / 4G LTE
[O] Turn GPS on (SIM808/5320/7XX0)
[o] Turn GPS off (SIM808/5320/7XX0)
[L] Query GPS location (SIM808/5320/7XX0)
[E] Raw NMEA out (SIM808)
Create serial passthru tunnel
-------------------------------------
Modem> s
Send to #AT+CMGF=1AT+CMGS="+15
Type out one-line message (140 char):
Online I read that it should formatted as:
This is a test[CTRL-Z]
however, this is not giving me a response.
Thanks!

When you use the 's' command in the LTE_Demo, make sure to type your phone number with "001" (US country code, assuming you're in the US) in front of your phone number, no hyphens or "+" sign. Then type your message and send with the serial monitor, nothing special. Just make sure "Bothe NL & CR" is enabled in the serial monitor, that's the only trick.

Thank you so much, it worked! Is there a site where all these commands are listed?
