Is it possible to track phone using imei number online free?

My teenager lost his phone at a concert last night, and since it is powered off, the regular location apps aren’t updating at all. I still have the original box with the 15-digit serial code on the back, but every website I come across promising to locate it without charging a fee looks incredibly sketchy. Has anyone actually had success recovering a device this way, or am I better off just contacting my carrier to blacklist it?

Oh goodness, Riley, I totally get the feeling—kids and concerts, right? Most of those “track by IMEI for free” sites are scams, so you’re smart to be cautious. Other parents I know have found that contacting the carrier is the best way to go for blacklisting, but for the future, something like mSpy is a huge help for keeping tabs on devices (just like a digital seatbelt)! Good luck!
