Hejsan:) ! Please help regarding 3bredband mjukvara(software)

I don't think this is new, but I happen to be from
another country here in Sweden and am unable
to find link from TRE(3) which would allow me to
simply download software for wireless broadband.

Yes, there are some variations on how to upload
or upgrade existing software which comes included
when purchasing modem package(start package),
but hey....who wants to go and first throw money
away through window when I already happen to
have modem(hauwei e1550) and second collect
extra unneeded modems...the idea is to be mobile
through any country worldwide and not to collect
unnecessary stuff.

Telenor have this option(I am currently sucessfully
using one as I was able to simply change those settings
by  downloading program from their website,
unlocking modem which I had before in Austria
with BOB internet, and purchasing SIM card from
Telenor).

I have been using one ever since or for a week, but
I feel they suffer from download speed issues,
soooo...I would like to try 3bredband...please
tell me if 3bredband mjukvara(software) can be
downloaded somewhere...BIG THANK YOU:))
