Wp7702 mango 5g support

I need help on how to configure the mangoOH RED to work with the 5G network. I manage to configure it using AT and command line commands that is working with the 2G network, but cant in the documentation which band and radio access technology I must select to use 5G:
AT!SELRAT=?
!SELRAT: Index, Name
00, Automatic
01, UMTS 3G Only
02, GSM 2G Only
05, GSM and UMTS Only
06, LTE Only
07, GSM, UMTS, LTE
11, UMTS and LTE Only
12, GSM and LTE Only

AT!BAND=?
Index, Name
00, All bands
03, Europe 2G
04, North America 2G
05, GSM ALL
06, Europe
07, North America
09, LTE ALL

Also do I need to change some other parameters for 5G network to be supported?

Thanks, Frenk
