Specification updated.
<https://wiki.ubuntu.com/Networking?action=diff&rev2=250&rev1=249>
** Changed in: ubuntu-ux
Status: In Progress => Fix Committed
** Changed in: ubuntu-system-settings (Ubuntu)
Status: Confirmed => Triaged
** Description changed:
Build r95 krillin
Steps to reproduce
1. go to System Settings > Cellular
2. under CELLULAR DATA there are three options: OFF, SIM1 and SIM2
3. tap on SIM1, you will have the option to select between 2G ONLY (saves
battery) and 2G/3G (faster)
Actual behaviour: tap on SIM2 and the only option available is 2G ONLY
(saves battery)
Expected behaviour: SIM2 should have exactly the same options available as
for SIM1, meaning that the 2G/3G option is missing. However, 3G connection can
not be enabled for both SIMs at the same time. So if SIM1 is set to 2G/3G, SIM2
will be automatically set to 2G ONLY. If SIM2 is set to 2G/3G, SIM1 is set
automatically to 2G only.
This switch would not require a reboot of the whole device and can be done
while the phone is switched on. The switch can take 10-15 sec (at least on
Android) and we will probably have to show some sort of spinner, to signal to
the user that switching is in progress.
This depends on ofono changes, bug 1373388.

+ <https://wiki.ubuntu.com/Networking#cellular-connection>: "As with any
+ radio list, if changing the connection type is taking more than one
+ second, the radio mark for the new value should be replaced by a spinner
+ until the change is complete, whereupon it should revert to a radio
+ mark. If choosing a different connection type for one SIM (for example,
+ from 2G to 2G/3G) forces a change in the connection type of the other
+ SIM (for example, from 2G/3G to 2G), that change should be shown
+ immediately."
