Huawei G730 is good phone i love the ROM they have.
You did not found Google play because of it rights issue.
Huawei have given There market place with phone, just go there and install all the things which you want... Search goole play in that and install it. I works like a charm.
You can install all the products of google from there app store like Gmail , Google Play , Youtube etc.
I am using this phone since 2 month and its working damm good. I am looking for the Kernel of the phone just to customize for my knowledge.
