Hello guys!
I'm happy to be now a member of this list! I read some messages in the archives
and understood that I _should_ subscribe! :)
I have an Huawei E3131 device - it reuses the E398 ID, and similar
disfunctions.
First of all - this hardware version doesn't support LTE, and has been boughton
Italy. the "ati" commands reports:
Manufacturer: huawei
Model: E3131
Revision: 21.157.41.01.1037
+GCAP: +CGSM,+DS,+ES
at^hwver says:
^HWVER:"CH2E303SM"

^VERTIME:Apr 19 2012 15:16:47
So it seems a pretty recent firmware version.
As you know for sure, the device actually has the same ID as the E398, see
attached lsusb; and is handled by the option driver (for the serial ports) and
the cdc_ncm driver (for the wwan interface).
Even in this case, the commands:
at^ndisdup
or
at^ndisconn
returns an "OK" message, but the modem will not ever try to connect to the
network.
ModemManager, in a debug session, ended up using the 2plain ppp connection".
I wanted to inform you all about the fact that:
- I have the device
- I can help in testing
And hoping someone has some ideas about this.
thank you all for your help!
