NO CARRIER

1. Why this NO CARRIER is comming?

eg, viewtopic.php?f=37&t=3986&p=15720#p15717

It’s not “garbage” - it is PPP data.
The module has been asked to create an IP connection, so it expects the external device to respond with IP packets in PPP format.
Because it doesn’t get any PPP/IP packets, it drops the call - hence giving NO CARRIER.

The modem is working correctly!
