I tried to do things the right way by ordering a nano SIM from Verizon. Today I tried to activate my MXP online. When I entered the IMEI, it told me that it was not valid. So, I called Verizon CS, and explained what I was doing. I was told that they would need to submit a form to add my IMEI, and it would take 2-3 days. I have a Verizon store in the next town over, so I figured I would drive over there after work, and get it activated. After I explained what I was trying to do to their greeter, the smug little **** looked at me, and said "Until Verizon approves that phone for our network, we will not be able to activate it". At that point I thought to myself, why did I even bother? I drove back home, trimmed the micro SIM from my G4 into a nano SIM, popped it into my MXP, and now it works just fine.
