My question is can I add LTE band 3 to my OP3 A3000?

Mine currently supports:
North America model(A3000)
FDD-LTE: Bands 1/2/4/5/7/12/17/30

The other models support:

Europe / Asia model
FDD-LTE: Bands 1/3/5/7/8/20
TDD-LTE: Bands 38/40

China model
FDD-LTE : Bands 1/3/7
TDD-LTE: Bands 38/39/40/41

If anyone has done this or attempted to do this please let me know
