NONE! straight talk currently will not allow LTE phone in their system yet. only 3G & older phones are allowed and no verizon prepaid phones either. and flashed phones and esn cloned phones will not stay active on straight talk for very long. if you want an LTE phone on straight talk you would either have to buy the st AT&T/tmobile sim or buy the straight talk
samsung galaxy S3 which is on sprint prepaid non roaming network. and now straight talk
is letting customers bring your sprint phones to ST and i think you get LTE too.
