Let me post what I did and hopefully more of you will save yourself the trouble of the SIM card nonsense.
1. Get the box it came in. Don't even bother opening it.
2. log into Verizon account online.
3. Click 'Activate/Add a device' and select the line you want to use.
4. Put in IMEI and SIM card numbers.
5. It will tell you to choose a plan, unlimited is still selected by default.
6. Done.
7. Now open up phone, tuen on, and enjoy![]()
I followed the same process. However, my phone still wanted to show the dummy line number, so I gave Verizon a call. The first lady I spoke to told me that she was going to have to "mail" me a new SIM since the one that came with the phone was locked to the dummy line (not true, I hadn't gone through activation yet). I politely told her I could not wait for a new SIM to come in the mail and would just stop into a VZW store instead (i.e. hang up and call back until I got someone more sensible).
The second rep I got was very knowledgeable and finished the process on their end. He double checked everything on my account, had me eject and re-insert the SIM tray, and made sure my LTE was working. A few minutes later, I was up and running with the iPhone 5 on my usual line, no extra SIM needed.
Did that first rep REALLY think someone who was calling in to activate as the UPS guy was pulling away was going to wait until a new SIM got mailed? Sheesh..
