The invention relates generally to a system for providing an roaming carrier list to a remote wireless device such as a vehicle communications package (VCP), while largely overcoming several shortcomings of prior techniques. A more intelligent Off PRL Wireless System is proposed that will scan all wireless bands including opposite cellular bands and PCS. The VCP will place test calls to the wireless carrier found during the scan. All wireless carriers found during the scan will be used to populate the Off-PRL System Availability Table (the OPA Table) including those the VCP was detected as “Unavailable”. Each carrier in the OPA Table will be denoted as Available and Unavailable depending on whether the VCP was able to access the carrier. Once the fall scan is completed, the VCP will connect the carrier listed first as available in the OPA Table.
