Phone doesn't establish cellular data connection

[Jean-Baptiste Lallement]

I switched several times between operators and 2g/3g settings in system-settings without any Wifi connection, and at some point the phone stopped connecting to a cellular data network (no network in the indicator)

@Jean-Baptiste

This sounds similar to bug #1425987.

A few questions...

What was the SIM configuration you used? Was either SIM locked?

You also mention that you switched several times between operators? How? Did you use the System Settings::Cellular::Carriers page? How many operators were visible?

Can you still reproduce reliably? The key us being able to fix is first being able to reproduce your scenario. I can't really do this from the information provided so far...

Finally, we recently landed a fix for MTK-based modems which should fix some of the problems that occurred when switching between WiFi and mobile-data.

Also, I added a ofono (Ubuntu-RTM) task as you reported this against an RTM image, not vivid.
