Im getting the unlocked lilac s9+ from Samsung, and they ask who your carrier is , of course u have to put sprint , but same as boost mobile. And I'll will have sometime next week , and they say it can be activated soon as I get it, I no it better !!!!
I got the s9+ unlocked in the mail yesterday (yay) now im just waiting for tomorrow to activate it with that new sim card. When it asks you for a carrier, select UNLOCKED. Gotta make sure it is the unlocked version
