@delete, thanks. I see the error: AT+CGACT=1,1 +CME ERROR: 149
Looking at 3gpp 27.007, that is "PDP authentication failure". We are not using authentication as there is no user/password, so this is a bit strange. I have attached an "ofonod" binary that forces authentication, could you give it a try? To use it: * Deactivate cellular data in the device * Download the binary $ adb push ofonod /tmp/ $ adb shell $ chmod a+x /tmp/ofonod $ sudo su # stop ofono # OFONO_RIL_DEVICE=mtk /tmp/ofonod -nd -P stktest,provision,sap,udev,dun,smart,hfp &> /tmp/ofono.txt& Then do /usr/share/ofono/scripts/activate-context 1 and see the output. Also, please attach "ifconfig" output and ofono.txt. ** Attachment added: "ofonod" https://bugs.launchpad.net/ubuntu/+source/ofono/+bug/1504992/+attachment/4501641/+files/ofonod -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1504992 Title: Cannot connect to Simple Mobile APN To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ofono/+bug/1504992/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
