Is Red Rice dual sim full active?

Jul 24, 2014
I wan't to buy new phone but it has to have dual sim full active(meaning that if you talk on 1sim and someone is calling on 2sim it is active or if you want to call you can choose from which sim card you want to call, or if you are talking on 1sim and someone send you sms on 2sim you can read it and answer it with no problem being active on 1sim card) I have read that MTK6589 are full active and red rice 1s has MTK6589T but someone wrote that Red Rice 1s is dual sim stand-by. Can you tell me how works dual sim in Xiaomi Red Rice 1s as it is my favourite phone to buy? Thank you in advance for your reply.
