Don't know but it's not supporting any Redami mobile in my area
Then some Xiaomi handsets have some peculiar 4G problems. My other Redmi 2 Prime also has a peculiar problem. It connects to Vodafone 4G with no issue but I don't get any call during the time phone connected to 4G. Normally when any incoming call arrive phone automatically switch to 3g network but that phone doesn't and it stays on 4G as a result no incoming calls. I hv two Redmi 2 devices but this issue happens with only one. With other one I hv no issue.
I think this is the side effects of launching products without proper testing to save cost.
