Any tracking would have to be done by you or your sevice provider, if you linked your phone to your account, then simply typing "Find My Phone" in a google search will bring up it's location if it can be reached. To find out your phone number, again, contact your service provider. If you lost it 2 months ago, it's either used by someone else with another SIM or is dead and not reachable. You need to start looking for the phone the hour you lose it.
