I would believe it to be some other vendor than broadcom.

It probably would be supported by the mbm plugin.
The reason you get errors on atz is because it uses at&f instead (an 
alias sort of to atz)
Also, the modem comes up with cfun=4 (rf disabled) and an cfun=1 makes 
rf enabled.
Doing a cfun=0, which modemmanager currently does as close down, will 
power off
the modem...

My apologies, you are quite correct, it is a Dell Device: 
Bus 008 Device 004: ID 413c:8147 Dell Computer Corp. 
Device Descriptor:
  bLength                18
  bDescriptorType         1
  bcdUSB               2.00
  bDeviceClass            2 Communications
  bDeviceSubClass         0 
  bDeviceProtocol         0 
  bMaxPacketSize0        64
  idVendor           0x413c Dell Computer Corp.
  idProduct          0x8147 
  bcdDevice            0.00
  iManufacturer           1 Dell
  iProduct                2 Dell Wireless 5530 HSPA Mobile Broadband Minicard Device

The modem defaults to cfun=4 on startup, so one needs to issue a cfun=1 before using it to connect. You are also correct about AT&F working.

What is the mbm plugin?
