I connect fine but always get disconnected exactly after 120 seconds

[Hector Lopez]

Thanks a lot for the information. What should I do after this command:

AT+CGDCONT=1,"IP","fast.t-mobile.com","0.0.0.0",0,0

I deleted all the other PDP contexts but it always add the following
context automatically:

16,"IPV4V6","fast.t-mobile.com","0.0.0.0",0,0


Thomas, I get both IPv4 and IPv6 addresses (dual stack).

Thanks
