Mobile phones are a must today. The range starts from the bottom to the sky. Then how to buy the best? There are big brand names but they offer good phones at a huge price. So I would say it is good to invest in a not so big company . See, today the many new companies want to enter the mobile market and hence bringing their best cell phones at the lowest rate they can. You must have noticed phones giving extraordinary features at less rate. That is because they want to increase their goodwill in the area.
But for a safer side, always research hard on a product before buying. And look for their consumer care services near you if any complaints persists and then make your smart decision !
