3G modem works with wvdial but not with NetworkManager

Hello,

I'm experiencing a bug/strange behaviour using the Ericsson UMTS chip in my Thinkpad X230.

If I set up the mobile connection via wvdial and manually run wvdial in a shell, I get a working internet connection. Actually, I'm posting this via 3G right now.

If I set up the mobile connection via NetworkManager using the very same parameters, NetworkManager tells me that a working network has been created, but it does not work (everything just times out).

I've collected logs of wvdial, NetworkManager and ModemManager together with the generated routing tables and anything else I could think of. The paste is available here:

Does anyone have an idea where the issue could come from?

Best regards,
Raphael

Re: 3G modem works with wvdial but not with NetworkManager

I have the some problem with my Huawei E226...
wdial config:

[Dialer hsdpa]
Phone = *99#
Username = wap
Password = wap
Stupid Mode = 1
Dial Command = ATDT
Modem = /dev/ttyUSB0
Baud = 460800
Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
ISDN = 0
Modem Type = Analog Modem

With NetworkManager I can't connect to any mobile broadband, even when I created the profile:

[connection]
id=Movistar Default 1
uuid=0ed17510-3881-445e-bc5d-7ce555cc0e33
type=gsm
autoconnect=false
permissions=
secondaries=

[gsm]
apn=internet.gprs.unifon.com.ar
number=*99#
password=wap
username=wap

[ipv4]
dns-search=
method=auto

[ipv6]
dns-search=
ip6-privacy=0
method=auto

Have you got modemmanager installed? NetworkManager lists it in Optional Deps:

modemmanager: cellular network support

Yes, I followed https://wiki.archlinux.org/index.php/USB_3G_Modem and https://wiki.archlinux.org/index.php/Huawei_E220 articles.
