For ppp configuration, I have two files, that I called both `motorola': one in
/etc/ppp/peers:

hide-password 
noauth 
connect "/usr/sbin/chat -v -s -f /etc/chatscripts/motorola" 
debug 
-crtscts 
/dev/ttyUSB0
460800
defaultroute 
noipdefault 
remotename motorola 
ipparam motorola 
nodetach

, and another in /etc/chatscripts:

ABORT BUSY 
ABORT 'NO CARRIER' 
ABORT VOICE 
ABORT 'NO DIALTONE' 
ABORT 'NO DIAL TONE' 
ABORT 'NO ANSWER' 
ABORT DELAYED 
'' ATZ 
OK-AT-OK AT+CGDCONT=1,"IP","internet.wind"
OK-AT-OK AT+CGQREQ=1,2,4,3,6,31 
OK-AT-OK AT+CGQMIN=1,2,4,3,6,31 
OK-AT-OK AT+CGATT=1 OK-AT-OK ATD*99# 
CONNECT ''

.  Moreover, in /etc, I have resolv.conf:

nameserver 193.70.152.25
nameserver 193.70.192.25

.  According to what you suggest, how should I edit those files?

.  But I use the sim card that's inside the device only to naviate in internet,
not also for voice calls.

Thanks indeed,

Rodolfo
