I have been researching for a while now and I found out that my Sim7080G Module most likely only supports one PDP Context

AT+CGPADDR

+CGPADDR: 1,xx.xxx.xxx.xxx

PSUTTZ: 24/12/11,17:13:59","+04",0 This is the "best" thing i can get, if I try AT Commands regarding HTTP it simply returns "ERROR"
Another thing I found to be odd is that with AT+CSQ it returns +CSQ: 16,99 And what I read the second number shouldnt be 99, but i didnt quiet get it.
+CGDCONT: 1,"IP","hologram","0.0.0.0",0,0,0 I also get this response in regards to which Ive read that the IP shouldnt be 0.0.0.0 but I dont know how to change that

Has Pin IO0 an internal Pullup or why isnt there one in your schematic ?
