Dear SteveWAD,
For all questions related to the setup and operation of the tracker, we recommend that you contact the seller or manufacturer directly, they will have the most complete expertise on this issue.
As far as we can see in the instructions on the Internet (for example, https://manualzz.com/doc/7363938/primeat-plt-user-manual) for this device, it needs to have Internet access in order to working properly.
Please contact your local mobile provider for a suitable SIM card (to make sure the GPRS service is available) with the appropriate data plan. You can also check with your mobile provider for APN settings.
More information about SIM cards can be found in our blog –https://gps-trace.com/en/blog/about-sim-cards-for-gps-trackers.
if you have additional questions, please let us know, we will try to help you.
