Use this code :

PHP код:

new tower = GetClosestTower(playerid);
if(tower == -1) // No Signal
{
    PlayerTextDrawSetString(playerid, Textdraw2, "~w~Phone Signal - ~r~I I I I I");
}
else
{
    new Float:dis = GetPlayerDistanceFromPoint(playerid, tInfo[tower][tower_Pos][0], tInfo[tower][tower_Pos][1], tInfo[tower][tower_Pos][2]);
    if(dis > tInfo[tower][tower_Signal] / 5 ) // Bar One
    {
        PlayerTextDrawSetString(playerid, Textdraw2, "~w~Phone Signal - ~g~I ~r~I I I I");
    }
    else if(dis > tInfo[tower][tower_Signal] / 25 ) // Bar Two
    {
        PlayerTextDrawSetString(playerid, Textdraw2, "~w~Phone Signal - ~g~I I ~r~I I I");
    }
    else if(dis > tInfo[tower][tower_Signal] / 50) // Bar Three
    {
        PlayerTextDrawSetString(playerid, Textdraw2, "~w~Phone Signal - ~g~I I I ~r~I I");
    }
    else if(dis > tInfo[tower][tower_Signal] / 100)
    {
        PlayerTextDrawSetString(playerid, Textdraw2, "~w~Phone Signal - ~g~I I I I ~r~I"); // bar four
    }
    else 
    {
        PlayerTextDrawSetString(playerid, Textdraw2, "~w~Phone Signal - ~g~I I I I I"); // bar five
    }
} 


Your code wouldn't work as expected because if player is in range of tInfo[tower][tower_Signal] then he is also in range of tInfo[tower][tower_Signal] / any_natural_number because
x > x/natural_number.
