  3. Hello,
    I have a modem Huawei E3531s-2 branding by Swisscom (swiss provider).
    Firmware version: 21.318.35.00.103
    IMEI: 867424022826873

    The modem is locked with Swisscom SIM card, I try to change the firmware, but it’s not possible.
    It’s also unpossible to unlock with a code, for use the modem with an other provider.

    Is someone has a solution please ?

    Thanks
