A reliable cellular signal is vital for your Samsung Galaxy A15 5G to make calls, send texts, and stay connected online. If your phone frequently loses signal, it can be immensely frustrating.

• Software Glitches: Outdated software or corrupt system files sometimes disrupt cellular connectivity.
• Conflicting Apps: Rarely, a specific app can interfere with your phone’s ability to connect to a cellular network.
