So I picked up my new 6+ today from UPS will call at 8:30. Looked over the phone and everything looked good. I decided I would use my old sim card just because and swapped the old one for the new one. I then powered up the new 6+ and went through the setup process to include the activation. I then downloaded the MyVerizon app and checked my status. It still showed my line with unlimited data. So I then checked to see if it updated my device which it did show the new phone. So I then checked my upgrade date on my phone which showed it had been updated to reflect the 2 yr upgrade. Logged in once I got home tonight and it still shows me having unlimited data. Needless to say I am a happy camper! I ordered the phone from Apple and not Verizon directly so I am not sure if this had something to do with it or not. I am waiting for my wife to get home so I can do her phone the same way and see what happens. Her phone was ordered directly from Verizon so I am interested to see if her line maintains the unlimited data or not. I will be sure to update this once she gets home to the findings.
