    Hey Shar,

    Thanks for the question.

    Almost all iPhone models are dual-band, meaning they can operate on both the CDMA and GSM network types. I'd advise following the steps for activation with the SIM card that was sent out to you.

    If you have any issues along the way please check out our SIM card support page!

    I tried following the directions, but:

    -It never asks me to input my sim card number. It goes from step 3 to step 7.
    -When I try to call the number it either doesn't do anything when I press the green call button or it will say, "Starting Service Update," then .01 millisecond later it will say "Service Update Failed."

    I have an IPhone 6.

    Hi Ashley,

    Activating your phone would depend on the SIM card type that you have. I would recommend taking a look at our SIM card activation tutorial videos here. If you aren't sure what type of SIM card you have, please reach out to our chat support team for assistance with that.
