This trigger will fire when it detects that a particular cell tower or group of cell towers is in/out of range. This is a low-accuracy location method useful for identifying presence in a general area such as a town or city, as cell tower coverage typically spans many kilometers.
Options
- Enter Cell Area - The trigger fires when at least one cell tower from the selected group becomes detectable, confirming you are within the group's coverage zone.
- Leave Cell Area - The trigger fires when no cell towers from the selected group are detected, confirming you have moved outside the coverage area.
After selecting enter/leave, you will be taken to the Cell Tower List screen where you can:
- Create a new cell tower group by scanning visible towers at your current location
- Select an existing cell tower group
Cell Tower Groups
Cell tower groups are collections of cell tower IDs that define a geographic area. To create a group: 1. Go to the location you want to define 2. Add a new cell tower group and scan the visible towers 3. Give the group a meaningful name
The trigger compares currently visible cell towers against the saved group to determine whether you are within or outside the coverage area.
Examples
Example 1: Turn on WiFi when arriving at home area
Triggers Cell Tower Change [Enter Cell Area: Home]
Actions WiFi On
Example 2: Silent mode when leaving home city
Triggers Cell Tower Change [Leave Cell Area: Home City]
Actions Set Ringer Mode: Silent
Notes
- Cell tower-based location is less accurate than GPS but uses significantly less battery power.
- The trigger polls cell tower information at regular intervals. You can configure the update rate in MacroDroid Settings.
- Setting the update interval to 0 uses a 30-second interval.
- The trigger listens for real-time cell location changes when the device is awake.
- On Android 8.1+, location services must be enabled for this trigger to work.
- The trigger requires the SCHEDULE_EXACT_ALARM permission on Android 12+ for reliable timing.
Permissions Required
- ACCESS_FINE_LOCATION
- ACCESS_COARSE_LOCATION
- READ_PHONE_STATE
