A:AnswerIt is best to buy the phone unlocked then you can use whatever carrier your device is compatible with whenever you like. If you buy it locked then the carrier you chose will have to unlock it. You will have to meet your carrier's criteria before they will unlock it. As an example, some carriers require that you have active service for a set amount of time before they will unlock your device. If you are uncomfortable attempting to unlock your device then I would find a walk in store for your carrier and ask them to assist you with the unlock.
A:AnswerYes, and no..
When I bought it it said Verizon. But after I put the SIM card in my service was not happening. So I was in the phone with Verizon for hour or maybe 2. Officially it's not listed on their end as a serviceable phone through them. However, after going through 3 engineers at Verizon, they finally figured it out. It was something to do with the fact its a VO LTE, 4G.
Idk the difference between LTE and VO LTE. BUT..they got it going. So maybe now they know how to get it cell service. Otherwise it's a good little phone. Good luck
A:AnswerMint uses T-mobile which has GSM raradios. This phone has nano SIMs and should easily work with Mint. I recommend getting a Tudia case for it as well.
A:AnswerI'm sorry, I don't know anything about your carrier. I have Cricket and it works fine with it. All I needed to do was remove my sim card from my old phone (which was a ZTE BladeX Max) and put it in the Nokia 7.2.
