Hello guys, the same here in Czech Republic. Many users getting dual-sim phones and this trend is even increasing by new companies selling these phones with a very good specs (Samsung Galaxy S IV Mini Duos, Xiaomi Hongmi, Lenovo, HTC, LG, Sony, ZOPO phones etc.) Please consider to support this feature as it may help to many your users. I believe the times have changed since this was a very rare feature of just few phones.
Thanks in advance.
