If you rushed to the settlement site to claim the $25 check that Apple must pay to iPhone 6, 7, and SE owners after a class-action lawsuit over performance slowdowns, you might have been left feeling frustrated and disappointed. It’s not the amount, it’s the search tool.

The site says you may be able to locate your old phone’s serial number by entering the Apple ID and device type along with the name and address last associated with the iPhone in question. We weren’t able to find an iPhone 6s that we still have in our possession using the tool, and we’ve heard from readers who say the same. We’re not sure if it’s the result of a bug or strict search parameters, but it’s certainly frustrating.

But even if you can’t find your old phone or it won’t turn on, you might still be able to find your serial number and claim your cash. Here are five ways to track it down.

Very helpful for those of you who want to take part in the settlement but no longer have the eligible iPhone.
