    SIM Card - have you tried using that SIM card in a different phone, it's possible that it already needs to be replaced

    PC Slow Charging - the USB ports in most PCs deliver only sufficient current/power to read whatever device is connected through it; this amount of power is not the same as the power delivered by official chargers; hence, charging through PC USB ports will always be "slower".

    Volume reset - I can't comment (I'm running 10581, but on a different phone).

    Right.

    Have you tried performing a soft reset then? a hard reset? It has been noted elsewhere that resetting a Windows Phone under Technical Preview should resolve the SIM detection issues the owner of that phone is experiencing.

    Soft reset = press and hold power button and volume down button until your phone reboots.

    Hard reset = go to your phone settings > about > reset your phone.

    These are generic potential solutions that usually resolve software-related issues in most digital devices.
