So I found a phone in a store for $40 and it seemed to suit my needs, it says it comes with Boost! mobile services (I dont quite understand how that works either) but I am planning on buying this phone and then using a cellphone provider from overseas. (im currently in the USA and will be moving out soon. So is it possible to just buy this phone and then use it overseas with a local provider? How can i tell if it is locked to one provider?
