Nexus 5 LTE Band 40 missing

So the carriers in India has only LTE Band 40 in my state. And my Nexus 5 seems to be missing the band 4 that is 2300MHz.
On the other hand LG G2 has the same Snapdragon 800 and has the band 40. Any way in which we can modify the modem to include the band 40 in it?
I have a LTE connection yet i can't use it. Duh. :(
Any help is appreciated...
