still has same problem, its connected but no internet in karmic.
i tried it in jaunty and its working but it is not detected so you have to do this first.
e1550 in jaunty jackalope
sudo apt-get update && sudo apt-get install udev-extras
echo 'SUBSYSTEM=="usb", SYSFS{idProduct}=="1446", SYSFS{idVendor}=="12d1", RUN+="/lib/udev/modem-modeswitch --vendor 0x12d1 --product 0x1446 --type option-zerocd"' | sudo tee /etc/udev/rules.d/45-huawei1550.rules
and you can firefox in jaunty. but not on karmic.
then send mo na sa 2225. Use a cellphone in that. Then text Balance after a minute of sending that messege to 2225, then move that sim to that E1550 and plug it in the Ubuntu. Nalaman ko kasi na magiging connected ka pa rin on the network manager kahit wala kang load, wag mo nga lang asahan na may internet ka.
yes, its actually an activation issue, you have to balance inquiry so it will be activated at first time use. i also use wammu software to access the usb like a phone so i can balance in the laptop without removing the sim, it can make your sim faulty by repetitively removing and inserting it.
