Hey there, Akira! No. You would need to contact Apple to do that. With Apple's, and your friend's help, you can restore it. You can find Apple's support page about the subject here.
I'm sorry, but if it was at a Boost Mobile store, you will need to go back to the place of purchase to see if they can provide you with that information. We do not handle that information from this side of the company.
Hey there, @IsmaelT1205! Thanks for contacting us. You can use the email that was sent to you as a confirmation of the purchase. That is why our customers are asked for a valid address every time they purchase a phone. Please check your Inbox or your SPAM/JUNK folder. It should be there!
Hi there, Kevincent! Let us help you with this. Have you tried checking your email spam/junk/promotions folders? If you still can't find the order confirmation email, please send us a private message with the name and address used to place the order so we can try to locate your order.
