[xenial] cellular data switch is inactive and cellular-data-usage cannot be switched between sim-cards

luksus42 commented 6 years ago

Device: FP2
Channel: 16.04/RC
Build: 16.04 (2018-W28)

Steps to reproduce

Slide down the connection-settings-panel and try to switch the cellular-data switch. or
Go to settings/network (cellular settings) and try to switch the cellular-data switch and watch the setting-options.

Expected behavior

The cellular data switch can be turned off. In cellular settings, one could decide between first and second sim-card to be used for cellular-data.

Actual behavior

The switch is turned on and greyed out/inactive. In cellular settings beneath the switch, for each sim-card-slot a message says: "No simcard found [...]".

But the simcards are there and I can use them. I also can decide which simcard should be used for phone and messaging. But not which simcard should be used for data.

Logfiles and additional information

https://docs.ubports.com/ gives me a cloudflare error 1014 "CNAME Cross-User Banned".

Not confirmed on hammerhead (Nexus 5). All fine here.

One or two simcards? I can confirm that it's working fine with one simcard only.

While testing for one simcard I also found a fix:

remove second simcard
reboot
(shut down)
add second simcard
(re-)boot

Now everything works like exspected.

I can confirm smth is fishy here, but not with the cellular data switch, which works fine for me:

As other phones the FP2 can only have one radio in 3G/4G mode. So, switching the speeds from EDGE to a higher speed means the other radio needs to switch back to EDGE. This works on the E5 for example smoothless, whn you change the speed the list entry for the second one will follow after a brief waiting time. On the FP2, wehn mobile data is on, changes to the speeds are ignored completly. YI need to switch mobile data off. Changing the primary SIM card for data seems first to work, but then no data can be sent/received. Also here, disabling/enabling mobile data helps. So summary: I did not have to remove any cards, but I had to try/error a few combinations to remedy my data connection. However, once set, the settings remain stable, even after reboot.

Workaround for me for switching SIM cards:

Disable mobile data
Switch cards
Enable mobile data

Workaround for me for switching speeds:

Disable mobile data
Set both cards to 2G
Enable mobile data
Set new speed on one SIM to 3G or 4G

Sorry that I cannot provide an ofono or logcat log ATM, I am on the run, maybe tomorrow ;)

Mobile data switch stuck "On"

I was able to reproduce this bug in both 15.04 and 16.04. To do so:

Insert at least one SIM into your Fairphone 2 and boot it
Enter flight mode
Leave flight mode

After doing this, the Cellular Data switch will be disabled in the "On" position and mobile data will not function. Sometimes it'll take a try or two to actually reproduce the issue.

This is possibly related to #382. However, because it is also found in 15.04 it is NOT a regression and can be removed from this milestone.

Unable to switch mobile data between SIMs

I was also able to reproduce this, but I'm not sure if it's just my American mobile network being weird with having the same phone contact it using two radios. Specifically, I have to do as Florian mentioned to switch data between cards. However, I am able to reproduce this in both 15.04 and 16.04 so we'll be removing this issue from the backlog and re-targeting it along with bug fixes for other devices in later releases.

Hi, have you picked one of your SIM-cards to be used for mobile data? Today I did a clean install of 16.04 stable (using ubports installer, device: BQ E5 vegetahd). After that I thought I had the same problem. But I found that I had to tap on one of the SIM-cards to be used for mobile data [settings/network (cellular settings), just underneath the switch for mobile data]. Then I could switch mobile data on and off as usual.

Unable to switch mobile data between SIMs

This has been fixed by https://github.com/ubports/ofono/pull/5. The cellular data switch becoming inactive is still an issue.
