I am 30 plus years into my career and have made a few job changes - I have acquired a number of contacts along the way. Many are subcontractors or former coworkers who I consult with. The two phones worked for awhile but had to re-create the contact when I turned in my last company phone. On the next job I moved to a single personal phone to keep the contacts. I have been independent for the last 4 years and although the last company closed my email access, they did not purge the phone.
