The question will verizon give me a sim and will i be able to activate it? Will all features work and will it show up on my verizon ect.?
No Verizon will not give you a sim and activate it because it's not on their system.
However, if you already have an active sim from Verizon, then yes it will work on t-mobile/AT&T.
----------
You can't use an unlocked T Mobile device on Verizon because they are a CDMA network and all T Mobile devices are GSM.
The Verizon version of the iPhone 6 has dual network ability with both CDMA and GSM, that's why they will work on T Mobile and AT&T.
Bottom line is if your on the Verizon network, your going to have to buy a Verizon iPhone 6.
Actually, Verizon network will work on any unlocked AT&T/T-mobile device. I've done it and it works. You have to have an active sim card. I happen to have a verizon ipad mini Retina with an active sim. I've inserted it on my att 6 plus and can confirm that it does work.
It is just that Verizon will not activate the new sim card since it's not registered to their network.
Just an FYI T-mo/ATT/Verizon 6/6 Plus (except Sprint) has the same A1549/A1522 model number.
