Hi there, @joseguardado47! Thank you for contacting us. Definitely want to help you with this. Are you using the SIM card that came with the phone?
Hello Spkatph. Unfortunately, it is not possible to activate an unlocked phone on an existing account. You won't be able to swap into the new unlocked iPhone. The Bring Your Own iPhone program is only available for new activations. You can find details here.
I'm using the same SIM card which is on my IPhone 5s. Switching it over to my New IPhone XR. I tried purchasing from your website but it says sold out for over the last 3 months. How can I get my IPhone to work? Can I get a new SIM card?
