The apn setting is taken from the settings I used with an earlier Huawei modem (E392) that did work on this computer.
I have indeed tried the present modem on a windows machine to verify that it worked at all. I just tested again, and managed to get a 4G network connection using online.telia.se. I also removed the PIN, but could not find any settings to restrict the connection to any particular type of network on the windows network manager that Huawei supplies. Retesting earlier suggestions after that test on windows brings up somewhat different responses from the script and a steady blue light (not blinking) from the modem, but no working internet connection, and no wwan0 interfae visible as far as I can see: $ ./huawei-4g-linux.pl Huawei 4g modem (E3276 and possibly others) script by Janhouse (Janis Jansons).
