Useless – Opensignal Internet Speed Test Review

I just wanted to see cell network signal strength at my location on T-Mobile. Then I wanted to compare it to other cell networks. It let me see T-Mobile's coverage one time only. Once I chose to see all carriers at once on the map, it did not let me go back and see only T-Mobile again or select to see just any other single carrier's signal strength by itself either. Waste of time.
