Выполнил шаги, описанные тут: http://www.linux.org.ru/view-message.jsp?msgid=1875299, только скрипт /etc/ppp/peers/cdma-evdo чуть изменил:

921600
connect '/usr/sbin/chat -s -v "" "AT&F0E0V1S0=0" OK ATD#777 CONNECT'
debug
updetach
crtscts
noipdefault
nodetach
novj
lcp-echo-failure 0
nobsdcomp
novjccomp
nopcomp
noaccomp
noauth
user belcel
modem
usepeerdns
defaultroute
connect-delay 5000

в /etc/ppp/pap-secrets, соответственно:
belcel * cdma
cdma * belcel

Теперь запускаю:
pppd /dev/usb/ttyACM0 call cdma-evdo

и получаю фигу:

CDMA 2000 modem init: press <ctrl>-C to disconnect
Serial connection established.
using channel 11
Using interface ppp1

В общем, несмотря на якобы подключение, Интернета нет, ни Firefox, ни Konqueror не загружают ни единой странички. Где искать проблему?
