Notes:
2.3 Use 3rd party APP to locate the tower(s)
1) Now open “Opensignal”, use it to detect the approximate position of the nearby cell
tower.
2) Insert your detail address in “Search city” box. (following figure 1)
3) Enter signal dashboard, and click “CELL TOWERS”. Then zoom in map to find best one, it
will show a blue line with your place which means your cellphone connected one.
(following figure 2&3)
4) When you find such location, check the strength, test voice and data speed. A good
signal shall not only be strong, but also be clear in voice and fast in data speed.
Just remember that strength and quality are two separate issues. A poor quality “strong”
signal can be next to useless, but a clean signal of two bars might be all your device needs.
