Found following solution working on OTA-12:
Within Terminal:
/usr/share/ofono/scripts
./test-network-registration /ril_0 default
Switches back to hsdpa if available without disconnection from the
network.
Testing with
ping 8.8.8.8
If there is no reply the network manager service hangs, then
sometimes it happens to me, it loses the connection (in the top bar icons
appear like connected), but if I try to access to network (webbrowser, ping
etc) I haven't any access.
What do you need to track the bug?
In my case the phone is bq 4.5 ubuntu edition with OTA 11.

I'm noticing that this bug is a few months old, however since the OTA-8
update it has become significantly worse for me. I'm using a BQ phone
E5HD model and I'm in an area with generally patchy coverage. I get
reasonable coverage at my house and very good coverage at my place of
work, however

Same issue here with meizu mx4 and ota6.
In the train and while driving.
When issue happens, icons for data and signal hang on last connexion

Switching plane mode on/off fix the issue.

@costales
One other thing to check... did you have more than one SIM installed in
the phone? We've been working on a bug where the mobile-data SIM
selection can switch to the wrong SIM after a reboot or operator switch
/re-registration ( such as what can happen when signal is lost ).
See bug
@Tony, no, just 1 SIM card ;)

@costales
Was it only data that didn't recover? Or was voice and SMS also
affected?
Also, do you recall whether or not your phone displayed an icon for
mobile data ( eg. '3g' or 'H' ), or did it just display the icon that
looks like an empty WiFi icon?
Finally, if you do hit this problem
@Tony, yes it's complicate to replicate, but I travelled 2 times in
train without mobile cover, and the mobile can't recovery the 3G
connection after that.
The terminal it's a BQ Ubuntu 14.10 (r20), last updated 3/19/15.
Best regards!
