Is it possible to enable certain LTE bands on Lumia 640?

[Windows Central Question]

Is there a way to enable an LTE band on Lumia 640?

As far as I know, Lumia 640 supports all LTE bands, but they might differ in certain models (RM-1072 vs RM-1073). It'd be great, if there was a way to enable LTE 3 and 20 bands on RM-1073, like it is possible on Nexus 5 (D920 - D921), using field test.

Can you access Field Test on your phone? If yes, follow this guide (same concept used on UMTS Bands but theory holds for LTE).

If you cannot access Field Test, then you need to cross flash to a compatible ROM from within the same family. See here: http://forums.windowscentral.com/no...after-reset-flash-process-defined-inside.html
