Raspberry Pi Cellular IoT HAT – not connecting to Verizon wireless

I am unable to connect to internet using Verizon wireless Nano SIM with RPi Cellular IoT HAT. Maybe I am doing something incorrectly and needs some help.

Current status
Installed PPP with the following values
Cellular IoT HAT, CATM1, vzwinternet, n, ttyS0, Y in the order requested

Also I do not see an indicators / lights ON for the Cellular HAT. Also there is no other HAT or sensors attached to the GPIOs

The following are the error msg from running “sudo pon”

Hi Jag,

It should be a micro sim. Please, use the right size of SIM.

Here are the instruction to get started

Thanks for the suggestion, my bad.

          Currently I have micro SIM card inserted and worked with Verizon in getting activated (they say the card is activated).  The following were the steps followed
  1. Using getting started guide - did the software setup cmds
  2. uninstall & installed the PPP with ttyS0 and again using ttyUSB3 - I am still unable to connect to internet.

*** with ttyS0
warning: alarm synchronization problem
Script chat -s -v -f /etc/chatscripts/chat-connect -T vzwinternet finished (pid 1602), status = 0x3
Connect script failed

*** with ttyUSB3
/usr/sbin/pppd: In file /etc/ppp/peers/provider: unrecognized option ‘/dev/ttyUSB3’

Settings used
Cellular IoT HAT, CATM1, vzwinternet, n, ttyS0, Y in the order requested
Cellular IoT HAT, CATM1, vzwinternet, n, ttyUSB3, Y in the order requested

Also I have connected USB -Kybd/mouse) to one of the USB to the RPi.

Please let me know, what am I missing.


Seems the module is not powered up.

What is the behavior of the LEDs?
