A:Answer The Samsung Luna Pro does come in both GSM and CDMA style, but it does not come on the one SAME phone. It Tracfone model and Total wireless model are CDMA models, they use Verizon network. The Simple Mobil Luna Pro Model: SMSAS337TG3P5P is a GSM model it use T-Mobile network, also there is model for Verizon, ATT and/or T-Mobil also. If you buy a unlocked GSM phone then u can use it on any network that use GSM band wave(ATT and T-Mobile) but not on the CDMA band wave(which are Verizon and Sprint), like AM radio don't work FM, and FM radio don't work AM.
