Trying to use this hat to get internet access on a Pi 2. Followed this tutorial. But, I can't seem to get it to work.

What's weird (to me), is if I'm connected to the LAN through ethernet, I get different results.

If I'm connected to the LAN and run sudo pon fona, I get a ppp0 interface, but the Pi doesn't appear to be using this interface. If I disconnect the ethernet cable, ping adafruit.com gives me ping: unknown host adafruit.com. cat /var/log/syslog | grep pppd shows this.

Using a Cricket BYOP SIM in the U.S.

If I'm not connected to ethernet, and run sudo pon fona, I get no interface, and the Pi recieves a termination request from peer:

The link to the tutorial you posted answers your second question for automating the connection.

Edit the /etc/network/interfaces file by executing: 

sudo nano /etc/network/interfaces

Then add the following lines to the file:

auto fona
iface fona inet ppp
    provider fona

This configuration will tell your device to bring up the FONA PPP peer automatically on boot. The configuration in /etc/ppp/peers/fona will be used to set up the PPP connection.

Thank you for posting this question and the link to the tutorial. It helped me establish internet connection on startup on my Raspberry Pi B+ (running Raspbian Jessie 2016-05-27) in connection with the Itead SIM800 module.

Edit: For powering on the module on startup you need to add the following lines to a startup script (I added it to /etc/rc.local before the line exit 0)

sudo echo 17 > /sys/class/gpio/export
sudo echo out > /sys/class/gpio/gpio17/direction
sudo echo 1 > /sys/class/gpio/gpio17/value

I found this hint here.
