Can you please enable WIP debug logs and check what is the problem if seen in logs.
+wipping:1,0,0 shows that timeout occurs before connection.
There could be many reasons for failure like congestion between the host and target etc.
You can try with increasing the timeout period and see if response is received or not.
Sometimes even when you establish gprs connection, you can not open a socket or create connection to a remote server because the gprs connection is not ready. In this case, you need to wait a few seconds just after gprs connection completed.
Rarely I encounter with this case. You can have a try.
I have the same problem with WS6318 (L30.1_00gg.WS6318 140312), AT+WIPPING command do not work.

As you can see WIPPING command to respond ping-fail while TCP connection (WIPCREATE) work fine at the same time. Possible we need to ask for WS6318 price discount…
