    That's correct, without a supported SIM card you can't set up the phone.

    If your carrier supports unlocking, you can use any SIM after your phone has been unlocked by the provider:

    iPhone: About unlocking

    Follow the instructions in this article to unlock your iPhone for use with different carriers.

     

    Follow these instructions to initiate the unlocking process for your iPhone:

    1. Check if your carrier offers unlocking. Only your carrier can unlock your iPhone.
    2. Contact your carrier and request an unlock.
      • You may need to meet certain requirements to qualify for unlocking. After your carrier submits the unlocking request, it may take up to seven days.
    3. Once you receive confirmation from your carrier that your iPhone unlock has been processed, proceed to the next section.
    If you have a SIM card from a carrier that is different from your current carrier, and you've received confirmation from your current carrier that your iPhone is unlocked, follow these steps:
    1. Eject your SIM card and insert the new SIM card.
    2. Complete the setup process.
    If you do not currently have another SIM card you can use, follow these steps to complete the process:
    1. Back up your iPhone.
    2. Erase your iPhone.
    3. Complete the setup assistant and restore your backup.

    1. Restore your iPhone.
    2. Contact your carrier to verify that the unlock was applied in your carrier's system.
