This is so slim and fashionable in design. And for the sim card and memory slot any phone that you can buy sharing the two slot for sim like vivo and oppo. I have 4G sim and I launch an application for just a second! I have problem in my SD card and my camera so laggy. asus zenfone 3 Max ZC5TL is not volt support. It has not long life battery, Clearity in camera and sound is also not good.
I think you are expecting to get a high end phone for that price but please bare in mind this phone is not too expensive and standard. This mobile is Not so reliable and easy in use.
