RC7620-1 AT command AT+CGCONTRDP < gw_addr> blank


I use RC7620-1, send AT command AT+CGCONTRDP, the gateway address is blank.
Is this normal? Other APN, local address and DNS address are displayed.
Could anyone help me with this problem?

didn’t it already show something in AT+CGCONTRDP

But the gateway address is not shown.
We need to know the gateway address.

on my side, I saw the following where it can show gateway address for profile 2 (APN: ims), maybe this is network dependent:

+CGCONTRDP: 1,5,hkcsl,,,,
+CGCONTRDP: 2,6,ims,,,,,,,,,
