can someone please help or tell me how I reach a human?

Humans are here but you will have to be understanding that you are asking about a very specific piece of hardware and not one I have ever heard of so there is a change no one would even have any idea.

Just doing a cursory glace are you sure the APN is set like they talk about in this example: https://how2electronics.com/internet-with-a9g-low-power-gprsgps-module-arduino/

also I can’t read chinese and the only technical document I see is this one: http://wiki.ai-thinker.com/_media/a6_a9_a9g_gprs_user_manual.pdf which is on their wiki: https://ai-thinker-open.github.io/GPRS_C_SDK_DOC/en/hardware/a9.html

Hologram SIMs do not support voice calling, which is why you are receiving the NO CARRIER response.

It would be good to confirm that you have set the APN on your device to “hologram”. You can set it by issuing AT+CGDCONT=1,"IP","hologram"
