This brand have a huge network, But the customer service is too bad.when I had the Y11 model, I went to the customer care, but they did not repair that.whatever, this model have a good design, feels very good, runs on marshmellow and sound quality is not bad.But the things I don’t like about this device is its poor battery life, weak proccessor, Absence of 4g band and the price.you can actually get a 4 times better 4g phone at this price.Even apple 4g iphones are availevel at this price.
