can my a1586 iphone 6 work on verizon

[adamglobe]

I am desperate for help.

I am American. I live in America. I have a Verizon account. But I work about half the year overseas and always buy a local SIM card when abroad.

So I recently needed a new phone while working in Europe, so I went to the Apple Store in Madrid and asked for an unlocked iphone 6 that I could use all over the world with local SIM cards.  They sold me a a1586 for about $800. It worked great in a few countries, including Switzerland, with local SIM cards.

Then I flew back to USA and I cannot get it to work with my Verizon SIM. I went to three Verizon stores and they insist it will not work.

I read online that I should activate my Verizon SIM on an iphone5 and then slide it into my iphone 6. I did that. It worked in the iphone5, but it still wont work on the iphone 6.

Please help

I think you need the 1549 for US.  Looks like you got the Sprint version.
