Public bug reported: I can't use my cellular data connection any more. The problem occurred after upgrading to OTA 12 but not directly afterwards. I use 2 sim cards (SIM 1 congstar for calls, SIM 2 orange for cellular data). System- settings shows me that only one of them (the one which I don't want to use for cellular data) can be found. This affects only the cellular data section. I can use it for calling and text messages.
I tried to delete several config / cache files and to swap the sim cards. I think this line in /var/log/syslog shows the problem: Aug 8 16:49:36 ubuntu-phablet ofonod[2115]: ril_data_reg_cb: DATA_REGISTRATION_STATE reply failure: GENERIC_FAILURE ** Affects: ofono (Ubuntu) Importance: Undecided Status: New ** Attachment added: "Screenshot of system-settings" https://bugs.launchpad.net/bugs/1612572/+attachment/4719573/+files/screenshot20160812_120453794.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1612572 Title: Cellular data connection fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ofono/+bug/1612572/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
