1st post so bear with me I have a company issued AT&T 4s that was due for an upgrade back in May. All upgrade requests come via a company website program. Currently the only apple phone available is the 4s through the company website. There was no iphone option for over a year so they are very slow to offer new phones. My regional manager has given me permission to upgrade to a 5s on my own if I can figure out a way to get it activated. I would pay for the phone myself and charge my branch via lunches using my company credit card until I recoup the money paid for the phone. He approves all my lunches etc via my company issued credit card. How do I purchase a 5s and activate it to my current cell # when I do not know what the last 4 digits of SS# the company uses or zip code? We have many branches throughout the US.
