Dual Sim Active Dual LTE enabled Mobile Phone- Suggestions Needed

Kindly suggest me a Dual Sim (Both Sim active, not dual stand by rather dual acttive) mobile phone in range of 15000-20000 which has the following features

1. Screen 5 to 5.5 inches

2. RAM 2GB

3.Both sim active and both must support 4G as I am planning to use Warid and Zong sims simultaneously.

Thanks and regards

While I understand that you are looking for a dual-SIM active (also called dual-SIM, dual active) LTE mobile phone, please check this recent thread which was implicitly about dual-SIM stand-by LTE phones:

As you already know that a majority of the dual-SIM LTE mobile phones have only one LTE radio/modem -- to save cost, as well as to reduce SAR (specific absorption rate), and to decrease strain on battery -- I suspect that you will have to search a lot for your desired phone.

Any idea, even if its an expensive brand.... which one to buy

A quick search for LTE and "dual call" on gmsarena.com using google led to these phones (in addition to the Honor 6 Plus):
