Loaded airtime on a device and the new airtime does not reflect on the system after 3 hours.
If you call the device and it goes directly to voicemail, please contact your installer to check if there is power on the device.
Other issues that may cause your device not to update is poor signal strength.
Our minimum recommended signal strength is 14.
If it is below this ensure that the antenna is not mounted inside a metal enclosure or against any metal and mounted vertically.
The antenna must be at least 2cm from any metal.
