1. Windows Central Question's Avatar
    I have a sim-unlocked AT&T Lumia 1020 (RM-877). I loaded the 10586.29 build of Windows 10, and had to reset the phone using the Device Recovery Tool. After that, the phone was sim locked again. Re-entering the unlock code worked, but has this happened to anyone else?

    (I checked the status using ##7820#)

    My ATT lumia 830 shows it's locked when using ##7820# but it still works with my non ATT sim card.
