SM-2GE-SFP-CU is not supported on 1900 routers and you can only install ONE EHWIC-1GE-SFP-CU.  You can't install more than one EHWIC-1GE-SFP-CU on a 1900 router. 


If you really want two routeable ports then you'll have to settle with a HWIC-2FE instead.  


Besides, a 1900 router will never be able to push anything close to 1 Gbps per interface.  Save your money and get the HWIC-2FE instead.

Cisco recommends the 1921 for up to 15 Mbps WAN circuits, so it's not really a suitable router for LANs using FE or better.  You might want to consider obtaining a L3 switch.
