Pelephone 3G modem and NetowrkManager

[Tzafrir Cohen]

Hi

I tried to use my mobile phone as a gsm modem.
I had strange error at the PPP connection time. Basically along the
lines of:


PAP authentication succeeded
** Message: nm-ppp-plugin: (nm_phasechange): status 8 / phase 'network'
sent [CCP ConfReq id=0x1 <deflate 15> <deflate(old#) 15> <bsd v1 15>]

LCP terminated by peer (PDP context activation failed, no network protocol running)
** Message: nm-ppp-plugin: (nm_phasechange): status 5 / phase 'establish'

Modem hangup

(This is from running NM_PPP_DEBUG=1 NetworkManager --no-daemon )


After some debugging and consulting the #nm IRC channel, it eventually
turned out that the problem is in the APN value I used. It contained an
extra space in the end.

The source for that extra space is:

$ grep -A8 Pelephone /usr/share/mobile-broadband-provider-info/serviceproviders.xml
                <name>Pelephone</name>
                <gsm>
                        <network-id mcc="425" mnc="03"/>
                        <apn value="internet.pelephone.net.il ">
                                <name>3G</name>
                                <username>pcl at 3g</username>
                                <password>pcl</password>
                        </apn>
                </gsm>

Note the 'value' attribute of the <apn> tag.

So if you want to connect there, make sure you don't have a trailing
space for the 'apn' value.


BTW: wvdial turned out to be generally simpler and with more chances of
working. But you have to tell it which TTY to use, which is annoying.

My current wvdial.conf: (I used 'wvdial Samsung pelephone')
