Reproduced. syslog attached. Steps: 1. Start the phone 2. Check that you have network connectivity 3. Disable WiFi 4. Check that you cannot connect to network although cellular data is ON.
The mobile context was up, cnmi0 was up, phone was attached, but "ip route" showed nothing. Adding a default route for ccmni0 made "ping 8.8.8.8" work. Recent research has shown that rild in krillin sets ups ccmni0, but does nothing with routes, so this points to NM, as it is the one that should add the route. $ system-image-cli -i current build number: 270 device name: krillin channel: ubuntu-touch/ubuntu-rtm/14.09-proposed last update: 2015-04-14 16:00:29 version version: 270 version ubuntu: 20150410.1 version device: 20150408-4f14058 version custom: 20150409-665-29-206 ** Attachment added: "syslog" https://bugs.launchpad.net/ubuntu/+source/ofono/+bug/1378416/+attachment/4376062/+files/syslog ** Changed in: network-manager (Ubuntu) Status: Expired => Confirmed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1378416 Title: [krillin] disable WiFi, Mobile Data not available Status in network-manager package in Ubuntu: Confirmed Status in ofono package in Ubuntu: Invalid Bug description: STEPS: 1.

The debug.txt in comment #3 clearly shows that mobile data is connected via the list-modems output and list-contexts output. This output also agrees with the nmcli output which shows /ril_0 as connected. The smoking gun here looks to be the routing table, which is empty.
