Xiaomi Redmi 4A it is really a good phone under Rs 5999. And also it has very good features with nice processor chip set, I must say that I brought this phone from amazon for a exclucive price of 5000, let specified you about this :
It has 3120 mhz enough battry life.
2Gb of ram which really good for this price of phone.
Processor is may be 1.5 octo core.
And 16Gb of internal storage.
A micro sim card tray with Dual sim slots.
13mp rear and 8mp front camera.
But let me tell you one thing eigther you incert 2sims or only one sim and one sd card allow you.
Other wise this phone is really good and satified phone.
