I am very interested in the samsung finesse. I went to the straight talk website and typed in my area code and it brought up 4 phones. the finesse was one of them. At my local walmart they don't have this phone displayed. would the finesse phone work if i bought it because it come up for my zip code?how long has straight talk been at your walmart? do you have the finesse there? if so how much does it cost there? also I have a verizon plan right now can i bring my phone number with me? thank you = )
