4G IoT HAT not Working

Raspberry Pi Network HATs 3G/4G&LTE Base HAT
1

Greetings! After following instructions for the PPP Installer on RPi HAT, the script reports: “Connect Script Fails” following running pin, after reboot.

The carrier APN is “Xfinity Mobile” (in exactly that case) and the port selected was “ttyS0”.

These settings seem to work sometimes, but mostly, the connection is not stable.

Using sudo pin, the Script chat reads “…-s -v -f /etc/chat scripts/chat-connect -T Xfinity Mobile finished (pud 2472), status = 0x1
Connect script failed.

Would you have any advice please?

Many thanks!
