The first problem is the "chat" command which misses "-E", so the environment variable addressed inside the script is never used and the script breaks. The second problem is the that you cannot assume an Option card when you did "not discover a Novatel". In my case the script tried to set the mode with the Option AT-command which failed on the Huawei stick. Unfortunaltely I don't have a correct command for that device, so I just want to start the connection without any mode set before thus using the defaults.
