Great exercise which will help the entire bitcoin community. You won't find any issues with all your 4 points with these 3 companies. The 3 of us are legit companies and all great choices for Indian bitcoin users.

Hi Zebians

We have just launched Zebpay iPhone version:
https://itunes.apple.com/us/app/zebpay-bitcoin-wallet/id944854686

Zebpay iPhone app now has the buy vouchers feature that was there on Android.
Buy bitcoins feature is coming soon on iPhone.

We look forward to your feedback. Thank you so much.

Hi Singapore

Happy to announce the launch of Zebpay Android / iPhone app, a bitcoin hot wallet.

Zebpay aims to be your daily bitcoin spend wallet, a wallet to keep a few bitcoins and give you options to spend them.

We are looking for partnerships from companies who are aggregators of estore vouchers, mobile airtime and merchant vouchers which we can sell for bitcoins to Zebpay users.

Download Zebpay from dl.zebpay.com and get 100 bits free. I look forward to your feedback.

As mentioned repeatedly in this thread, wallets are not country specific.

If looking for an Indian specific wallet means that you want options to spend bitcoins in India, then check out Zebpay Android / iPhone wallet app. (Disclaimer: I am the co-founder).

Zebpay is targeted to be a very simple mobile wallet. You can store a few bitcoins and use Zebpay to buy Flipkart, Amazon India, Makemytrip vouchers at a 10% discount. We are adding more options to use bitcoins like the ability to top up mobile airtime.   

You can also buy bitcoins at the lowest price in India.
