Bug Description


1. Have a Sim card with data in a Nexus 4
2. Be in your office connected to wifi
3. Send some texts to confirm that you are receiving signals
4. Leave your office to go meet someone
5. After leaving, get a bit lost and activate the web browser to look up a map

You are now lost because there is no 3g data, though you can text and call

The phone switches to data for you

Note that sometimes it does switch to 3g data

Just tried this and found that I had no trouble switching wifi/3g and sending receiving sms.

I am now seeing this consistently. I haven't been able to connect to 3g since yesterday.

I just confirmed that JB4.3 on a Galaxy Nexus handles this flawlessly. Connected to my home Wi-Fi network, then left and went to the lobby downstairs without first de-activating Wi-Fi. By the time I'd gotten to the end of the hallway ( ~100 meters ), the Wi-Fi connection had dropped and the phone switched over to the mobile network. Almost no gap in being able to browse the web.

I will try and confirm this on Touch later today.


Not connecting to 3G at all ( especially if Wi-Fi is disabled ) is a separate bug. There's a new version of NM in -proposed that fixes what we believe to be the remaining issues with initial mobile data connection setup.

This bug was fixed in the package network-manager -

network-manager ( saucy; urgency=low

  * debian/patches/provisioning_wait_ofono_properties.patch: rework when we
    get the IP config from oFono as to get the values prior to transitioning
    to stage 3 (IP Configuration), so that we don't risk missing some of the
    settings. (LP: #1226071, #1225393)

I can confirm that the fix works with this package.

I have a similar bug to this although does not involve WiFi. If i am driving/travelling through an area that does not have reception from my mobile network. 3G/data does not come back when the phone has reception again. I can text and make calls but cannot use data. I have to power my N4 off and back on again to resolve this. Toggling the Data switch in the cellular settings does nothing. I would love to file a bug for this but wouldn't have a clue where to do so...
