A:AnswerYes. Make sure you have the phone unlocked at the store and tested with a SIM card, even with a US SIM, just for the sake of getting reception.
I was in Brazil for business and just swap my US SIM for a TIM pre-paid and worked fine.
A:AnswerIf you are talking about buying an unlocked version of the phone and financing it via the carrier of your choice, you would have to contact the carrier. Most of the monthly prices you see advertised assume you are adding a new plan or tacking it on to an existing plan. I hope this helps answer your question.
A:AnswerIf iPhone is unlocked and sim free it can be used. Also remember this has a dual sim and can have 2 different numbers from 2 different carriers in this phone
A:AnswerI didn’t pay for my SIM card when I purchased my phone. All phones come with a sim because you have to choose a provider in order to use the phone.
