I bought an iPhone Xr from boostmobile.com.
I activated online using the IMEI. It shows up now in my device info under my account.
When I try to call someone, however, it tells me my phone isn't activated and in the About section of my phone (in Settings), it says for carrier and network: Sprint.
Hey there, @mas51! We're deeply sorry to hear that. Please provide us with your nearest cross street address and zip code, that way we can see if there are any outages affecting your service.
Nevermind, I turned my phone off, tried calling to activated, it kept saying the MEID was incorrect, when I hung up I turned my phone back on and it said it was activating.
