Moto g4 play is available on Amazon and there are exchange offers on Amazon for selected pin codes I think. You can check if exchange is possible to your pin code. right now I thought I saw some cash back offers. I’m not sure if any other site sells moto g4 play. It is an Amazon exclusive phone. And e3 is a flipkart exclusive one. I have Samsung class 10 memory card. It doesn’t support. I’ve used it in my low end device, but after inserting it in moto g4 play the phone doesn’t detect the memory card.I am not sure if there are other ways. but what I did I will explain -> Click on the phone app(a retro style phone icon). Top right corner you can see the pop down menu symbol. click on it and go to setting. Click on calling accounts and choose sim 1 or sim 2. And then you can choose the call forwarding settings and set your preferences
