Michael, Can you confirm if you are using the power supply that came with the shield? That 5V supply outputs 2.4A which is needed to ensure consistent TX/RX performance with the cellular network. If the unit is just drawing from the RPi or a regular 1.0A tyope of output there will be enough power for it to operate but not enough for it to perform correctly. The troubleshooting you have done indicates the unit is operational and the service is provisioned correctly. The power supply would be the first thing I would check.

Has there been any resolution to this problem? I am experiencing the same sympotms with a shield connected directly to a terminal and AT commands issues manually. The shield is connected to the provided power supply.

Sadly no. I was contacted by support staff but after a couple emails back and forth I was not able to get access to any support people that could help so I basically scrapped the device and decided to go with a different approach. I would prefer to have this shield working though :(
