What is the response of at!gstatus? Have you entered correct APN in at+cgdcont? Other user can make it work under australian network: > [@RC7620-1 problem registering to the network](https://forum.sierrawireless.com/t/rc7620-1-problem-registering-to-the-network/28095/5): > > Yes, setting APN before waiting for connection works. Thanks for that information. BTW, have you tried the latest FW?
