    Hi everyone,

    I have a BlackBerry Q5 running OS 10.3.1.1779. Everything worked fine in France with my French sim card until I moved to the US. I bought a T-Mobile sim card, made sure the phone was unlocked, and inserted the sim card in, but it says "Sim card not detected". In "Settings", though, it says the phone is unlocked. I called my carrier (SFR) which also assured me that my phone was unlocked. I don't know what to do.
    Please help! Thanks!

    Well, a good place to start would be by updating the old OS to something newer.

    I know, but I can't manage to do it. It stops right before the end of the installation process every time. I've tried and tried again so many times, I've deleted all apps, etc. Nothing worked, so I've given up on updating the OS...

    Did you try by connecting the phone to BlackBerry link in a laptop?
