Do you keep being returned to the packages page?
If you are then this will be the reason why your payment was not completed by your bank or financial institution, so although you have an account with us you do not have an active subscription. All you need to do to get up and running is select a package, make the payment and then the device you've added should begin tracking. You'll be able to access all the features available on Device Tracker Plus.
Alternatively, it could be that your card has expired, or your payment has failed. If you'd like us to check for you, please get in touch HERE and one of our friendly customer advocates will be happy to help you get back up and running.
