Googles getting more information than your carrier. Your carrier or any carrier knows about your cell phone and it's registration and hand off between towers. It doesn't know the network you are seeing. It doesn't know what competitor telcos are seeing. But your cell phone knows all that without a sim no matter what your carrier is. Law enforcement doesn't have access to this data at all.
