Verizon and Sprint phones are on the CDMA network and don't use SIM cards. Just turn it on and activate it. Only GSM phones (AT&T, Virgin, StraightTalk, TMobile) use SIM cards.
I can't activate until I get off work I just wanna make sure because the packing slip states sim was included and for activation instructions it says has 4g sim and customer receipt handy for 4G avtubation process
