I want to buy the Nokia Lumia 521 Windows Phone from Wallmart online, which says "T-Mobile pre-paid Nokia Lumia 521 4G smartphone". Is that the unlocked smartphone or do I have to unlock it to use with theStraight Talk network?
I am still using the old Samsung Galaxy device for the Straight Talk as in my area the T-Mobile network is not good. Should I have to go to the Wallmart store to talk with its salesmen or can I get the answer here? Anyone bought the same handset to use with the Straight Talk?
