could i track my phone down by the nymber

See the following from If your iPhone, iPad, or iPod touch is lost or stolen - Apple Support

Find My [device] is the only way that you can track or locate a lost or missing device. If Find My [device] isn't enabled on your device before it goes missing, there's no other Apple service that can find, track, or flag your device for you.

Have you tried contacting your carrier to see if they have a tracking service you could use?
