Whit AT commands and minicom it possible you can read about it here (http://ec.hobbykompetenz.de/index.php/2017/06/22/orange-pi-2g-iot-at-befehle/) use google translate, about Gammu cannot say  but it possible. 

Orange pi 2G-IOT still very unstable, I think it is not good Idea use it in any project , easy use Orange pi One and SIM800(https://www.aliexpress.com/item/1-pc-SIM800C-Development-Board-GSM-GPRS-Module-Support-Message-Bluetooth-TTS-DTMF-Quad-band-Alternative/32798586003.html). it will work more stable. 

We are already a few users of this board. We believe that it already has enough potential for support. I myself have managed to install armbian W.I.P, community on the 512mb of NAND of this card and works well.
Thanks

Already it is possible to see and write in NAND memory from linux, I have left a small guide (in Spanish,  use google translate) to be able to experiment with its use:

At the moment it has not been able to make linux boot from nand but mount it. Everything has been made possible thanks to the work of the gitub aib user (https://github.com/aib)

Has anyone tested if Wiring-OPI works with this board? Thanks!

Try LibreElec boot first with toothpick method.
https://forum.libreelec.tv/thread-2347.html
 
And then boot balbes150's image with toothpick method.
 
It will work.

What program do You record ? View this topic.

Here is the final image with activation multibootboot.
 
https://yadi.sk/d/FcNyXwmhurN2D

1. update u-boot with balbes150's aml_autoscript.zip( 0.6 version)
2. boot with sdcard which was installed latest debian img.
 
H/W acceleration isn't working properly.
balbes is working on it.

Oops. Sorry, wrong. If the chip s905x don't see problems using armbian. Recorded the image. Launched Android. Chose "Update&Backup" indicated "aml_autoscript.zip" from the media. Updated (this update enables multi-boot). Then - as described in this thread. To perform the initial configuration and can be used.

So far we find out that three different versions / revisions of Beelink X2 exists. All three are confirmed to work, the one I have, work.

Just give some moments, the screen does not come up strait since boot loader that we use, does not have video driver.

I have network issues with horrible low upload speed (one day per GB) ... so need to wait until those issues are resolved. I'll put on blog when images are changed.

confirm. working ))), but have error, maybe script.bin is not correct configurated

after some restarts get only one error 

Edit: after some restarts get only one error and stopped fast blinking led red blue

now I can see dram )))
