Lost iphone

If you are asking about an insurance claim, these often take 30-45 days to complete.

If a request on Find My is "pending", this means that the battery has run down or the phone does not have an Internet connection where it is located.

Keep checking to see if the status has changed.

See this support article→If your iPhone, iPad, or iPod touch is lost or stolen - Apple Support. If you put the phone in Lost mode that prevents the phone from being used. But you can’t find it unless it has an internet connection (Wi-Fi or mobile data), is powered on and has energy in the battery, and Find My was enabled on it before it was lost. The fact that it says “pending” means that the last condition is satisfied. But without power or an internet connection there is no way to track it.
