Is OpenSignal reliable?

Founded in 2010, OpenSignal has built a solid reputation for its flagship Android and iPhone app, which passively monitors the speed, coverage, and reliability of mobile networks on users’ phones .

5G has dramatically enhanced the reliable download speed of Opensignal users . In every one of the 20 markets we analyzed, mobile users enjoyed a reliable download speed over 10 Mbps when connected to 5G and in two — South Korea and Taiwan — the reliable download speed was over 100 Mbps.

Open signal, to my knowledge, isn’t white listed, so it’ll reflect your real life speed more accurately . Speed test with Tmobile servers, Comcast servers, or level 3 servers 🙂 they give the most accurate results. More servers closer to the user equals more accurate results.
