Mobile Cell Check is a free Android app developed by MEFWS. It allows users to check the signal strength of their smartphones using RSRP (Reference Signal Received Power) and RSRQ (Reference Signal Received Quality). Additionally, the app provides specialized information such as Earfcn, Cell ID, and Timing Advance.

The app supports multiple communication standards including 5G (NR) with experimental support, LTE, W-CDMA, and CDMA (operation not confirmed). It displays various items depending on the network, including PCI/SC, RSRP/RSCP for LTE and W-CDMA. For LTE networks, it also shows Carrier Name, Band, Earfcn/Uarfcn, Central Frequency, RSRQ, RSSNR, Timing Advance, and Cell ID.

Please note that a valid SIM card is required to use the app, and it may not work properly on Android 11 or lower. Some access rights, such as location information and phone permissions, are required for the app to function correctly. It is important to note that the app does not guarantee proper functionality if certain access rights are denied.

Mobile Cell Check is a useful tool for anyone who wants to monitor and analyze their smartphone's signal strength. With its comprehensive features and easy-to-use interface, users can gain valuable insights into their network connectivity.
