I hv bought Galaxy M51 fm outside of India, and it is made in Vietnam. NFC and Payment option is enabled in this set which is missing in Indian variants. Since after i hv bought this set i hv been operating in area where 4G+ network is not available, so i hv not seen 4G+ in my handset but its specs clearly shows -Data Speed: LTE-A(2CA) Cat6 400/50 Mbps; which r missing in specs of Samsung India sets. I hope CA is also enabled in this handset. Rest it will be clear when i go to some area with 4G+ network.
