First of all, excuse me if this is not the correct site to ask this question or if it seems too stupid, but I have been struggling with that for some hours and I couldn't solve it yet.
The point is that I want to insert a SIM card to a MyWigo City (http://www.mywigo.com/smartphones-mywigo/mywigo-city.html) but I don't know how to do it. It's a dual-SIM phone, but I can only see one slot for SIM cards. In the pictogram next to it, it says that I have to insert the SIM cards horizontally and one overlapping the other? It doesn't make any sense for me.
I tried all possible ways I could imagine and none of them worked.
