A:Answer The specifications say it is a 3G phone, so no it will not work with a 4G network.
Someone asked, 2 years ago, if it works with Verizon and the answer was "yes". Having said that, I think Verizon has, since that time, started blocking phones that they don't sell themselves (which IMHO, ought to be illegal). If you look at unlocked phones on Amazon and you see a lot of user comments about phones that the vendor claimed worked with Verizon, however, someone bought it and found out it didn't work (often times the seller asks them to contact them so they can walk them through how to make it work, so I suspect they are doing something to masquerade as a supported phone). Unfortunately Best Buy themselves does not monitor these Q&A things and do the research for you and give you an answer - you'll only get answers from other users, and frankly, this particular question can only be answered by someone who actually has one. I'm shopping for a new phone myself, so I can't answer you.
Sorry, I could only answer the 4G part..
