Opensignal has looked at the mobile experience of our smartphone users that changed their mobile operator in Brazil. In this analysis, we found that those Leavers that switched operators, or churned, generally had a significantly worse mobile experience before they switched, compared with the average experience of all users on their original mobile operator’s network. For example, on Opensignal data, on all four operators — Claro, Oi, TIM and Vivo — Leavers saw lower 4G Availability and a greater amount of time with no signal before switching.

When it comes to LTE reach, TIM Brasil has its competitors beat on two counts. It not only provided our users with 4G signals the most often but also in the most places. TIM rated highest in OpenSignal's 4G coverage experience metric, as our testers were able to find an LTE connection in 74.4% of the places they frequented in a recent three-month test period. That score was more than 7 percentage points higher than TIM's nearest rival Vivo.
