Performance comparison between Operators in same Country/City

Hi Experts.

In open signal website, there are report performance comparison between operators in same country.

Is there any link, app to compare operators in same city?

Try this Viettel Mobile (Viet Nam) Cell Tower Map

Thanks dear, but sorry, I don’t see operator benchmark…

It is jus crowdsourcing. Very few data for Vietnam.

For Germany there is lot of data.

I am looking for a website with benchmarking between operators.
