Collecting and keeping this data isn't something any police department is capable or permitted to do. Network operators don't just pass along their complete cell tower logs to the authorities. At least not where I live.

They do under a judge's order, a lot of murder cases or other heavy crime cases are solved that way.

It's possible that Israel is being more aggressive in using these measures but the ability to do this is trivial and I'm pretty sure the data is there in most countries. I don't know how much other countries use these ability though for Covid purposes though, it could be that they hold privacy as a higher value than tracking infected covid people.
