A:AnswerIt has to be opened. But if you already have a sim just activate it yourself. It’s as easy as putting the sim in and following on screen directions.
A:AnswerI just did this actually. You would need to get a new sims card from boost. But when I did mine a lot of other people were getting them at boost so they were sold out, so we got them from Best Buy, they were only $5 to buy them. Then you call customer service through boost and tell them you bought an unlocked phone and need to switch the new sims over to the new phone....
A:AnswerYes! I opened a best buy credit card and i’m able to
make payments monthly towards the phone. I also have 24 months to do so with no interest if paid in full by then.
