Who is SIM Toolkit & Network info for? Use it when you need your phone's model or software build, want to inspect available SIM details, or are comparing the information shown for two SIM cards on a supported dual-SIM phone. What does SIM Toolkit & Network info do? 📶 Show SIM and network details View available country, operator, and carrier information. SIM serial numbers and subscriber identifiers are shown only where Android and the device allow access. On supported dual-SIM devices, inspect the separate SIM entries and their readiness information. 📱 Identify your device Find manufacturer, brand, model, software version, and build details.

How does SIM Toolkit & Network info work? • Open the app and choose the information section you need. • Use the SIM, Device, or Battery tabs to inspect the relevant fields. • On a supported dual-SIM phone, check the entries for each SIM separately. • Use the available details when identifying your device or describing an issue to support. Some fields may be unavailable or show an unknown value. The app cannot display information that Android or your device does not make accessible. Compatibility and requirements The app is for Android and contains ads and in-app purchases. Available fields depend on your device, SIM configuration, Android version, and access permissions. Android restricts access to identifiers such as SIM serial numbers and subscriber IDs, particularly on newer versions. Not every identifier is available on every phone. Offline viewing covers locally available information. SIM Toolkit & Network info keeps available SIM, device, and battery information together for clearer everyday reference.
