# You can't spot switchers with a questionnaire. > Sign-ups, cancellations, provider switches: we see them in real transaction emails and bills. And we interview people right after they switched, while the decision is fresh. ## Why our data wins here - **Telco emails** Bills and contract confirmations from the inbox. - **Subscriptions** Streaming, software, mobile: sign-ups and cancellations over time. - **Apps** Installed provider apps and their usage as a leading indicator. ## A question you could ask tomorrow - Who cancels after the price increase, and where do they switch to? - Which bundles actually retain customers, and which are just dragged along? ## Where this matters most - [Churn & Win-Back](https://www.datapods.app/en/use-cases/churn-win-back.md): Who leaves, where to, and who comes back. - [Competitive Intelligence](https://www.datapods.app/en/use-cases/competitive-intelligence.md): Who you compete with, and where you win. - [Audiences & Segmentation](https://www.datapods.app/en/use-cases/segmentation.md): Segments from real behavior. And researchable. --- Source: https://www.datapods.app/en/industries/telco-subscriptions
