Hello, @Carfanatic! Unlocked devices require a different SIM card. In order to order the required SIM card, you will need to first determine the device is eligible to activate with us, and if it is you will be provided with the option to order one by clicking on the following link: https://activate.boostmobile.com/bring-your-phone?intnav=BotNav:Shop:BringYourPhone .
I have just received my unlocked by Samsung Note 10+ yesterday, and I can tell you my Note 10+ activated instantly with Boost Mobile without any problems.
