Requirements
This doc is tested on Alpine-2.1.3.
You will need a HSDPA USB-modem.
Use 'dmesg | less' to figure out which /dev/ttyUSB? it uses (you'll need to edit the configuration shown below to reflect the correct port number).
Install packages
Install the required packages
apk add ppp
Load modules
Now let's load the driver (using the values you just discovered) and configure Alpine to load it automatically at boot-up.
modprobe ppp_generic echo "ppp_generic" >> /etc/modules-load.d/ppp.conf
Config files
/etc/ppp/peers/E220
(The filename 'E220' can be changed, but you will need to remember it when running pon/poff command)
debug /dev/ttyUSB0 460800 crtscts modem noauth usepeerdns defaultroute noipdefault noccp nobsdcomp novj connect '/usr/sbin/chat -v -f /etc/ppp/chat-E220-pin || /usr/sbin/chat -f /etc/ppp/chat-E220-nopin'
/etc/ppp/chat-E220-pin
(The filename 'chat-E220-pin' can be changed, but you will need modify the config file shown above to reflect your decision)

OK "AT+IPR=115200"
OK "ATE1"
TIMEOUT "60"
"" "ATD*99***1#"
CONNECT \c
Routes
Create a default gw route to your 'ppp0' device.
ip route add default dev ppp0
DNS
Figure out what DNS-servers your provider has.
egrep -i 'pppd.*dns' /var/log/messages
This might give you some useful information.
Search for a IP-address that might be your providers DNS-server and add this IP-address into '/etc/resolv.conf'.
echo "nameserver {DNS-server-IP-address}" > /etc/resolv.conf
Start/Stop
Start connection
pon E220
Stop connection
poff E220
If something goes wrong...
Check if process is running
pidof pppd
Logfile might give you a clue on what went wrong
egrep "pppd|chat" /var/log/messages
Check nic information
ifconfig ppp0
pppd has a statusinformation function that could come in handy
pppstats
