does apple contact u about a stolen device by sms

No, it's a scam to try to get your log on information, ignore it.

Hello ~ No….that is usually someone that has possession of the lost or stolen device trying to get you to reveal your Apple ID and passwords. Have you responded or given out your information? If so:

If you think your Apple ID has been compromised - Apple ...

If your iPhone, iPad, or iPod touch is lost or stolen - Apple ...
