I can confirm that the Verizon iPhone 5 is indeed GSM unlocked.
Even though I bought an iPhone 5 from Verizon under contract, I
was able to cut down my AT&T Micro SIM, and use it in my Verizon
iPhone 5 to pick up an AT&T signal. By doing so, I was able to
hop onto AT&T’s HPSA+ network, or “4G” as they so ridiculously
name it. […]
I did reach out to Verizon via phone, and they confirmed to me
that the phone was unlocked, and that I could use it with another
SIM, even though I’m under contract, and just signed on as a
customer today. That’s great news for travelers, and a big win for
customers. Let’s just hope things stay this way.
That’s a nice surprise.
