Why my Galaxy Trend duos only has mobogenie but not play store?

[Basit Fahad]

I have bought Samsung Galaxy Trend Duos GT-S7562 from china. But it comes only with Mobogenie in it,not Google play store. I have downloaded Play store apk,but it doesn't help. Whenever I click on play store icon,a blank page appears and then disappears. What is wrong with my phone?
My android version is 4.0.4

Welcome to Android Central! Not all devices are certified for Google Play. It can be due to the manufacturer or the region in which it's sold. For devices like these, installing the Google Play Store apk file doesn't always work either. Sorry!
