Altitude Tech 3G HAT wvdial.conf file settings


Struggling through getting hologram setup on an Altitude Tech 3G HAT for raspberry pi 3. I’ve got the board fully installed/ recognized, etc using the instructions/ script it

However, now I’m receiving the dreaded “Bad Init String with wvdial”

Here’s my wvdial.conf

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,“IP”,“hologram”
Phone = 99**1#
Modem Type = Analog Modem
Stupid Mode = 1
Baud = 9600
New PPPD = yes
Dial Attempts = 0
Modem = /dev/ttyUSB3
ISDN = 0
Auto Reconnect = yes
; Password =
; Username =

lsusb output (altitude tech is the QualComm device):
Bus 001 Device 004: ID 05c6:9000 Qualcomm, Inc. SIMCom SIM5218 modem
