After Orange GPRS with Nokia 6630 and SFR GPRS with Nokia E65, I use now mainly Huawei 3G+ USB key with SFR (french mobile phone provider).
lsusb info about this Huawei 3G+ USB key:
Bus 003 Device 003: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem / E270 HSDPA/HSUPA Modem
And dmesg info:

For connecting, I tried an infamous GUI distributed by Vodafone in Debian package. Too buggy, too complex. The best solution is using a PPP chatscript.
Then, plug USB key, sleep 20 and unlock it:
echo 'at+cpin="1234"' > /dev/ttyUSB3
Note: 1234 is PIN code (or not) and /dev/ttyUSB3 is modem device.
Create these 2 files:
/etc/ppp/peers/gprs:
noauth debug nodetach connect "/usr/sbin/chat -v -f /etc/ppp/peers/huawei-e220.chat" /dev/ttyUSB3 230400 crtscts defaultroute noipdefault user ignored remotename whatever ipparam whatever usepeerdns
/etc/ppp/peers/huawei-e220.chat:

Finally you can:
pppd call gprs
