If you are experiencing sluggish data or dropped calls in a fringe coverage area, navigate to your phone’s cellular settings and turn off automatic network selection. Your phone will scan the airwaves and present a list of available local carriers. If your provider has a domestic roaming agreement, you can manually force your phone onto a stronger tower.

Older 2G GSM networks lack mutual authentication, meaning a cell tower can command your phone to connect without your phone verifying the tower's identity. Attackers use cell jammers to block 4G/5G signals, forcing your phone to downgrade to 2G, where they can intercept your traffic. Guard against this by going into your device’s security or cellular settings and toggling off "Allow 2G." Audit Your SIM Security If you are experiencing sluggish data or dropped
Program a strict handover hysteresis value (typically between 3 dB to 5 dB). The target neighbor cell must not just be slightly better than the current cell; it must exceed the current cell's signal strength by the hysteresis margin for a sustained period (usually defined by a timer parameter like TINIT ) before the BSC executes the switch.
