Hey there, @smc2109! Sim cards are not transferable between phones. If your iPhone XR is an unlocked phone (directly form the manufacturer) you will need to visit this link to check its eligibility: https://activate.boostmobile.com/bring-your-phone?intnav=TopNav:Phones:BringYourPhone If eligible, you will need to purchase a SIM Card for unlocked phone at your nearest Boost Store. Here's our store locator, if needed: https://www.boostmobile.com/stores.html
