Airplane mode acts as a reset for cellular signal. Rather than completely powering off your iPhone, you can switch Airplane mode on and off to see if signal improves. Turn Airplane Mode on and wait five seconds. Then, tap the Airplane Mode button again to reestablish that cellular connection. In some cases, a quick reboot is all you need to connect to a stronger nearby signal.
