Everything about your SIM cards, network and signal — in one clean, fast app.
SIM Card Info reads the details Android hides behind menus and shows them in one place: which carrier each SIM uses, how strong your signal really is, what network you are on, and how much data you have used.

PRIVACY
Everything is read directly from Android on your device. The app has no accounts and uploads nothing anywhere.
Note: Android does not allow apps to show data usage per individual SIM, and phone numbers appear only when the carrier stores them on the SIM.
