    I am planning on buying a sim-free unlocked iPhone XR, to upgrade from my iPhone 8 Plus. But will the SIM card that is in my iPhone 8 Plus work with the iPhone XR? Do they have different technologies that make them not work with each other?

    Also, just as a hypothetical, could you use a SIM card from an iPhone 6 Plus in an iPhone XR?

    The SIM cards are all interchangeable all the way back to the iPhone 5

    But wouldn’t an older SIM card limit data speeds since the iPhone XR has different cellular bands compared to the iPhone 8 Plus?

    Let's just say as a hypothetical. There are some rumors suggesting that Apple will have 5G in the 2020 iPhones. If that is true, and I buy an unlocked iPhone at that time, then would a SIM card from an iPhone 8 Plus work in a phone that has 5G networking?

    Hard to say. Who knows. It might not be know until a year from now when 5t rolls out and people may or may not need to change sims.

    In most cases the SIM card is just account information. Whether 3G/4G/5G

    It will not have any issues.

    Yes. Pull it out of your 6S and put it in your new phone and save the activation fee!

    I have done this with my last three phones.
