how can I switch a straight talk phone from at&t to Verizon

[examish Al]

I recently purchased a phone straight from straight talk and didnt realize it ran off at&t towers. Its a Samsung galaxy s4 with a sim card. Is there anyway I can switch it to Verizon towers??? Thanx

No, AT&T and Verizon use different technology in the phones.
