I live in us and use a t mobile prepaid sim, can i use this cellphone with that carrier in nj!?

I researched this model phone quite a bit, it will work with T-mobile. Put in your SIM card and enjoy!

Can the seller advise me if this phone will work with Digicel in the Caribbean (Jamaica)?

Yes it will... Bought one recently and it works with both Flow and Digicel
