Hello everyone, I’m planning on getting a pixel 9 to put GrapheneOS on. When it comes to the right phone to buy, you need a pixel that is “unlocked,” correct? Does unlocked refer to both root and carrier, or is there more than one meaning? Is there anything else I should keep in mind when buying a Pixel?

I was going to go with a refurbished one, would that be fine for security as well?

Thank you all

    An unlocked phone has nothing to do with an unlocked bootloader.

    An unlocked phone is a phone, on which you can change the carrier, by installing any sim card of any other carrier of your choice.

    Phones that have been on a monthly contarct are generally locked because the carrier locks you into their network and wants your money. However, at the end of the contract, some carriers will unlock the phone for you so you can sell it. or change to another carrier, without it being locked.

    sim free phones are unlocked so you can install any sim card of choice.

    You can still unlock the bootloader of a locked phone but it will still be locked to the carrier.

    buying an unlocked phone is the way to go.

    you can check the phone when you buy it. just put your current sim card into the phone to see if it connects to your network, and you can call and make text messages.

    It means Carrier unlocked. If it’s carrier locked (depends on where you’re from, what carrier it came from, and/or if it came from a plan upgrade), you may not be able to install GrapheneOS on it unless you get it unlocked first.

    If you get a second hand one, make sure the person you’re buying it from is willing to help you unlock it.

    First question in their FAQ: https://grapheneos.org/faq#supported-devices

    Devices sold in partnership with specific carriers may be locked by the carrier, which will prevent installing GrapheneOS. This is primarily an issue with US carriers and isn't common elsewhere in the world. To avoid this, either don't buy a carrier device, or make sure it can be unlocked. It's the same hardware/firmware/software either way but carriers dislike having devices able to bypass their paywall for tethering, etc., so they disable it for the devices they sell as part of contracts.

    You could also take a look at e/os or lineage which can be installed on like up to 14 year old phones and support more than just pixel
    But it might be not what you want so better inform yourself before deciding

    when people talk about unlocked phones, they mostly refer to the bootloader being unlocked. in that state the bootloader allows “flashing” (overwriting) the phone’s partitions, and that’s what you need for replacing its operating system.

    as I know almost all phones usually come with locked bootloaders, which is not bad because it provides security at least while it is on the way. but normally they can be unlocked. some manufacturers require custom account login and a working sim card for that, samsung started taking that away recently even retroactively for older phones.

    the carrier lock is a different thing, but if your phone is carrier locked, or it is a carrier variant, usually you won’t be able to unlock it (by yourself)
