I mailed a package to canada for the first time?

Ok so i had an old iphone 4 and i mailed it to my boyfriend in canada, Quebec to be specific. And i mailed on the 9th of june. The mail dude said it would take 7-10 days and… It passed through customs on the 15 but i haven't been getting updates on the tracker since it passed customs. Could it be it hasn't left the customs facility yet or i'm just not able to track it in usps tracking?

USPS only tracks to the border, when it handed of to Canadian Post. Your boyfriend will need to tel lyou when it arrives now.

Phones with batteries in them are prohibited in International Mail. It may be returned to you.
