Hi guys, new to this discussion but want to share my story. My wife and I both purchased the 6s on launch day from the Apple Store through the iphone upgrade plan. We decided to port our number over to att from t-mobile because of spotty coverage. So we purchased the att model and had no issues with the port. Turns out that my wife gets no signal in her office, so we decided to switch to Verizon. Since the phone is supposed to be unlocked when purchased through the upgrade plan, I assumed I could just take my phone to Verizon, have them pop a verizon SIM card in, and I'd be good to go. Not so much...
When the Verizon guy looked up my IMEI number he said he was unable to set me up with service. I called Apple Support and initially they said that my phone was locked to att. I was irate because the day I bought it I was told by the Apple employee it was unlocked and could be taken to another carrier. It so much as says the phone is unlocked when purchased through the upgrade program right on Apple's website.
So I called att and they confirmed that the device is locked, but I am eligible to have it unlocked, which I am in the process of doing online now. Hopefully it goes through and my device is unlocked and I can switch to Verizon.
Was I wrong in assuming I could take my phone from att to Verizon to begin with? If my phone does get unlocked, will I have issues switching over to Verizon? I suppose I could exchange the devices for Verizon phones at the Apple Store but really would just prefer to keep our existing phones.
