@Pat The suggestion from Alfonso was to fix this via a new page in the first boot wizard which would ask the user which SIM they'd prefer to use for mobile data. This would only be displayed if the phone detected more then one inserted SIM.
The general consensus from design was that this was less than ideal and that we should figure out how to do this automatically. Alfonso and I discussed this today, and it's my belief that we could do this by checking to see which SIM was inserted in the 3g capable slot and only setting the ConnectionManager's 'Powered' attribute to True for this modem. This would require us extending the GPRS interface to allow the ofono core to query the 3g capability of the modem slot, which is a very MTK-specific capability. If we implemented this, we'd need to figure out how to make this more generic. Note, bug #1413672 is related, and has a fix currently in-review. Finally, the fix for this bug cannot be deployed as an OTA update, it would require a factory image update, as this bug only occurs during first boot *if* the user had installed two SIMs before-hand. It also potentially could occur if the user resets the phone, but this scenario hasn't been verified. -- You received this bug notification because you are a member of Ubuntu Phonedations bugs, which is subscribed to ofono in Ubuntu. https://bugs.launchpad.net/bugs/1379412 Title: SIM selection for mobile data is non-deterministic Status in the base for Ubuntu mobile products: Confirmed Status in Ubuntu UX bugs: Triaged Status in ofono package in Ubuntu: Confirmed Status in ubuntu-system-settings package in Ubuntu: Confirmed Status in ubuntu-system-settings package in Ubuntu RTM: Confirmed Bug description: Our current implementation of SIM selection for mobile data is currently ( as of RTM #94 ) non-deterministic. If two SIMs are installed in the phone at first boot ofono will self- power the ConnectionManager interfaces for both modems which results in the 'Powered' property of both being set to 'true'. Only one of the two will attach to the network however, and if both SIMs are unlocked, this is usually the second slot. Note, if the second SIM is locked, then the first SIM is used for mobile data. The cellular system settings uses the 'Powered' property to choose which SIM is selected, so the current behavior is clearly broken. It was suggested that we should change ofono to not self-power it's ConnectionManager interface, and instead add a wizard page that allows the user to choose which SIM to use for mobile data.
