[phone]: phone network doesn't work

[Josué]

I saw that this happens in OS ubuntu for phones: ubuntu 14.10 r21 and I actually see this in ubuntu 15.04 beta r.223 (bq aquaris ubuntu edition)

When the battery of phone down tu critical value phone network doesn't works. Icon status of the top panel shows the network working. If you charge the phone (without restarting) the problem persists.
If you try to call in the phone app the top notification area shows you as "without service"
Wifi works fine all this time.

I think that the OS must notify you that the phone network will get closed for the critical battery and recover the network when you put the movil to charge. Maybe you must see this also in the icon of the notification top area.
