Lightweight phone (in weight and robustness) but quite in line with expectations for a low-end product and cheap. Clear menus, nice music (you can assign a different ringtone for SIM: Ideal to recognize immediately which line it is called) and "dual-sim" works perfectly, what was the purpose of my purchase. It is therefore a dual standby both lines are active pending call. Of course, when one receives a call, the other is disabled temporarily. In summary, a simple product but a priori reliable and well designed. Perfect for the price!
