doing a simple search on the web you find that your tablet only works with voip. Sim card is only for data. You can not call or receive a call.

    Do you have an official source for it? Or maybe a qualified post on xda Feb 25, 2019 at 15:35
  • I found it on a thread of stackexchange. As I am connected to Internet with my phone, I can not copy paste the subject of the thread. It mention this link : Source:huaweidevice.com/worldwide/… Feb 25, 2019 at 15:49

By looking around, it is possible.. However you need to make system modifications and literally build your system with a Modem & Call App... The best way I've seen is to actually try porting a firmware from a different tablet with the same chip set, that does have Call abilities..
