If you are using an iPhone to track your iTrack or iTrack2 and you are not receiving text messages for the coordinates then there might be an application on your iPhone might be blocking the text message.
By default, iPhone has no application that can block unwanted calls or SMS (text) messages but there are applications that you can install on iPhone that can do this function. For one, check if you have Blacklist apps installed on your iPhone. If you have it installed make sure to create exceptions for your iTrack or iTrack2. Second, if you have a jailbroken iPhone there is an application within Cydia that is available that can block calls and SMS messages. Make sure that you are not using this application.
If you do not have this apps installed on your iPhone and you are still having problems with your iTrack or iTrack2 feel free to contact our Technical Department for further assistance.
