reject it with

AT^SISC

.

command or the

AT^SISO

read command. Among other details, the response

indicates the IP address of the remote client (parameter

). This

may be helpful to decide whether to accept or reject the request.

2

Incoming Socket service client connection has failed. The client request was

rejected automatically because no free Internet service profile was available.
