Hi Tomato, thanks for your reply. Here are the output for the commands you like me to run. These are run on the Sierra eval kit with a EM7455 module and a Verizon SIM. The problem I am having is that the module cannot connect to the network.
The same module works perfectly with a Tmobile and AT&T SIM card.
