I don't know what's zebpay.
Zebpay is simple bitcoin wallet available on Android and iPhone, you can download it from
http://dl.zebpay.comIt allows you to send and receive bitcoins from your phone book contacts just like whatsapp. Also as whatsapp account here your wallet is linked with your mobile number so you do not need to worry about backups etc, you install zebpay, verify mobile number and you will get your account back.
You can buy bitcoins, buy vouchers at 10% discount, send and receive bitcoins quickly.
Thanks and Regards
