I’m thinking of buying from Amazon an unlocked version of the Google Pixel 4a for use on PagePlus.

Will PagePlus activate an unlocked version of this device?

Do carrier-branded versions of this device exist, or is every Pixel 4a sold in the USA unlocked?

I’d prefer not to buy a Tracfone-branded version of the device (if such a thing exists), in case I want to change carriers in the future.
