GPS Verifier requires push notifications to be enabled. To enable notification services:
- Tap the Settings icon.
- Tap Notifications (for versions prior to iOS 8, tap Notification Center).
- Select the GPS Verifier icon and set all available notification switches to ON. You can also choose to allow Banners or Alerts, according to your alert style preference.
GPS Verifier requires either a WiFi connection or mobile data to be enabled. Enabling mobile data should happen when you install GPS Verifier (it's a permission that is required to install the app), but it can be turned off afterwards, which will keep you from getting a GPS Verifier code. Enabling mobile data is different for different Android versions -- for 4.x Android devices:
- Open Settings.
- Click Data Usage.
- Make sure that Mobile data is enabled (checked).
