SIM Card Info: Signal & Data

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.

■ SIM CARDS
• One card for every SIM and eSIM, styled like the real thing
• Carrier, phone number, country, MCC-MNC (PLMN), carrier ID
• SIM state, slot and port, physical SIM or eSIM
• See which SIM handles mobile data, calls and SMS

■ LIVE SIGNAL
• Signal strength in dBm and ASU, refreshed every 3 seconds
• Live chart of the last minutes — walk around and find the strong spots
• Network type and generation: 2G, 3G, 4G LTE, 5G NR
• Roaming, mobile data state and voice network

■ CELL TOWERS (optional)
• The tower you are connected to: Cell ID, TAC/LAC, PCI
• Frequency channel (EARFCN/NRARFCN), band and bandwidth
• RSRP, RSRQ, SINR, timing advance, plus neighbouring cells
• Uses the location permission only if you switch this section on

■ DATA USAGE (optional)

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.
