Karbonn isn’t very popular brand in mobile history but some of Karbonn features phone is very popular in local market. I am using Karbonn K9 Jumbo around 2 years approximately and I am very satisfied with this phone.
First of all I like to say about the features of this phone. Karbonn K9 Jambu has a 2.4 inch TFT display, a large battery around 1800 mah, it has all basic features like Bluetooth, calculator, converter, games etc. Also I have to say that it has a very good features for a features phone.
I am using it 2 years approximately. Believe me guys there is no issue in that phone. It’s running so smoothly from the first day. it’s got very good battery life as well as its speaker power. I got around 5 to 7 days battery life in a one full charge. speaker quality is also very nice ( smooth and loud) . It support all type of videos music etc.
At last I am saying that I am very satisfied with this phone and it help me in every panic situation. I recommend to all of you if you want a basic features phone then don’t think just go for it. thank you
