If you intended to use the ZF2 as a dual sim phone, you should return now while you still can. Your second sim on 2G will be completely useless. As someone who has this phone, I'm already looking at other companies with enough LTE bands in addition to waiting to see what the ZF3 is going to actually offer. Don't get too excited about getting any OS updates either, Asus couldn't get its act together to go from 5.0 to 5.0 let alone 6.0. Asus own rep states with the Laser they are committed to giving the best experience on Lollipop 5.0 when asked if the Laser was going to get an update. LOL, there is no such thing with 5.0. Many other issues such as battery and dual sim handling could be solved by updating to 5.1 but they have not.
