MobileNetworkConnectionInfo (Function)
In french: RéseauMobileInfoConnexion
Returns information regarding the current connection to data on the mobile network.
Remark: This function cannot be used in the simulator and it will return 0 in this case.
// Activate the Wi-Fi if the signal intensity is strong enough to access the data
// via the mobile network
IF Val(MobileNetworkConnectionInfo(networkGSMSignal)) <= 20 _AND_ WiFiStatus() <> wifiEnabled THEN
IF YesNo("The intensity of the GSM signal is not sufficient. Enable the Wi-Fi?") THEN
<Result> = MobileNetworkConnectionInfo(<Type of information>)
<Result>: Character string or Integer constant
  • Requested information.
  • If several types of information are requested, each type of information is separated by a CR character (Carriage Return).
  • The order in which the information is returned (if requested) is as follows:
    1. <Type of network>
    2. <Operator>
    3. <GSM signal>
    4. <Roaming>
    5. <Plane mode>
<Type of information>: Integer constant
Requested information:
networkAirPlaneModeManagement of plane mode.
If this information is requested, <Result> is set to:
  • "1" if the device is in airplane mode.
  • "0" otherwise.
Universal Windows 10 AppiPhone/iPad This constant is not available.
networkGSMSignalGSM signal strength between "0" (no signal) and "100" (optimal signal).
iPhone/iPad This constant is not available.
networkOperatorName of the network operator used.
Depending on the type of network or if the plane mode is enabled, this information may not be specified.
If no SIM card is found, this information may correspond to an operator name if the phone is "Sim-locked".
iPhone/iPad This constant is not available.
networkRoamingData roaming mode.
If this information is requested, <Result> is set to:
  • "1" if the current connection uses data roaming
  • "0" otherwise.
iPhone/iPad This constant is not available.
networkTypeType of network used to access the data on the mobile network.

If this information is requested, <Result> will be an integer:
  • network2G: 2G network
  • networkEdge: Edge network
  • network3G: 3G network
  • network4G: 4G network
  • network5G: 5G network
  • networkUnknown: Unknown network (or SIM card not found).

WiFi connection information

To get information about the WiFi connection, use WiFiConnectionInfo.
Android Required permissions
This function changes the permissions required by the application.
The ACCESS_COARSE_LOCATION permission is added: this permission allows an application to access an undefined location (Cell-ID, WiFi).
Android 11 specific case: This function requires the ACCESS_BACKGROUND_LOCATION permission to access the device's location.
This permission allows using the function when the application is in the background.
If the application needs to use background location:
  • Manually add the "ACCESS_BACKGROUND_LOCATION" permission in the Android application generation wizard.
  • Explicitly request background location permission with PermissionRequest. For example:
    PermissionRequest(permBackgroundLocation, Callback)
    INTERNAL PROCEDURE Callback(p is Permission)
    IF p.Granted THEN
    // Functions that require background location access can be used
A window allows users to:
  • allow access to the device location while the application is in the background,
  • allow access to the location only while the application is in use,
  • deny access to the location. The user can also change these permissions at any time in the Android settings.

  • Follow Google's guidelines for applications that require background location access. For more details, see If these conditions are not met (especially user information requirements), applications may not be accepted for publication on Google Play.
  • The background location permission should only be requested if the location permission has been granted. Otherwise, PermissionRequest will fail.
  • If the option chosen by the user for the background location access request is more restrictive than the option chosen for the location access request, the application will be automatically restarted.
  • On devices running Android 10 or earlier, if location permission has been granted to the application, the background location permission will be granted without displaying a window.
