I thought someone will be interested with using two SIM's in lumia 1520.
Here is the sim adapter i bought
Brand New Dual Sim Card Adapter Converter for Apple iPhone 5 5th 5c 5S | eBay
I used two SIM's which worked fine (One is postpaid SIM from ATT and another is prepaid IPAD unlimited data sim). Switch between them is not smooth. Once I switched between SIM's using SIM application found in cellular network settings (only visible if you insert dual SIM adapter), I had to restart phone for the second network to be picked up. Since I need to switch to the second network only in emergencies it might work fine for me.
LTE worked for me from both the SIM's
