I recently procured a Huawei e1550 3G dongle, and subscribed to DiGi's mobile broadband services. At RM80 for the dongle, and RM70/month for the broadband service - the offer seemed to be a steal.

The dongle works perfectly in Fedora 13, and NetworkManager picked it up correctly. Here are configuration options for those planning to use DiGI mobile broadband on Fedora:

Number: *99#

Username: digi

Password: 9999

APN: 3gdgnet

Authentication methods: MSCHAP, MSCHAPv2

Compression: Allow BSD data compression, Allow Deflate data compression, Use TCP header compression

I had to fiddle with the settings till I reached the configuration above (usage of APN of diginet did not work correctly - you'll see successful authentication, and subsequent hangup).

Interestingly, when borrowing a colleague's Maxis dongle - it worked just out of the box, indicating a minor fix required with DiGi's default configuration settings in NetworkManager.
