I am trying to send data from a PI using hologram, I can get sms and everything else works, but after:

ATH
ATZ
ATQ0
AT+CGDCONT=1,"IP","hologram"
ATDT*99***1#

And running pppd as show here I get an error in the log:

Script /usr/sbin/chat -V -f /etc/ppp/umts.chat finished (pid 1346), status = 0x3
Connect script failed
Script /usr/sbin/chat -V -f /etc/ppp/umts.chat finished (pid 1354), status = 0x3
Connect script failed
Script /usr/sbin/chat -V -f /etc/ppp/umts.chat finished (pid 1361), status = 0x3

Connect script failed
Script /usr/sbin/chat -V -f /etc/ppp/umts.chat finished (pid 1365), status = 0x3
Connect script failed

I am doing something wrong? Do I need to change the “chat” file?

Thanks
