Hello Dmitri,
Remember me from this thread? https://forum.sierrawireless.com/t/mc7354-on-verizon-network/8821/1
Heh. It’s been a long time, no?
I’m still on the MC7354, so may not apply to you, but what I discovered was that the “IPV4V6” contexts don’t reliably work with our IPV4 stack. What I’ve found to work is change context 1 to “IP”, then enable context 10 & 11 – on the MC7354 those are already type “IP”. YMMV. Good luck. Let me know how it goes.
AT+CGDCONT?
+CGDCONT: 1,"IP","vzwims","0.0.0.0",0,0 <-- by default this will be "IPV4V6"
+CGDCONT: 2,"IPV4V6","vzwadmin","0.0.0.0",0,0
+CGDCONT: 3,"IPV4V6","VZWINTERNET","0.0.0.0",0,0
+CGDCONT: 4,"IPV4V6","vzwapp","0.0.0.0",0,0
+CGDCONT: 5,"IPV4V6","vzw800","0.0.0.0",0,0
+CGDCONT: 6,"IPV4V6","vzwadmin","0.0.0.0",0,0
+CGDCONT: 9,"IPV6","vzwims","0.0.0.0",0,0
+CGDCONT: 10,"IP","vzwadmin","0.0.0.0",0,0
+CGDCONT: 11,"IP","VZWINTERNET","0.0.0.0",0,0
+CGDCONT: 12,"IPV4V6","vzwapp","0.0.0.0",0,0
+CGDCONT: 13,"IP","","0.0.0.0",0,0
OK
