It has been confirmed by iDownloadBlog that the Verizon iPhone 5 is GSM unlocked. They were able to use an AT&T Micro SIM in a Verizon iPhone 5 and picked up an AT&T signal.
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.
iDownloadBlog contacted Verizon for comment and the company confirmed that the Verizon iPhone 5 is GSM unlocked and can be used with another SIM even while under contract. This is great news for anyone traveling overseas.
