Infibeam service was quick and accurate. A21 is good phone, priced at 6.7K with all the features that can one can get in this price range. Best part is its 1.2GHz processor its compensates for the 512Mb RAM. works smoothly for multitasking and for all current and favorite games.

It is best phone in the market at the best price... Beside saying one thing, it doesn't support 3G video calling through sim but only through skype ... You will be having almost all required features a android smart phone must be having... Every apps you install runs as smooth as you would have thought... Gaming experience is unbelievable... Temple run runs great,may it be anyone... But sometimes very slight sloppy with very high resolution games like pitfall... But nevertheless you must buy Samsung or Nokia or any other at the price rate above Rs.15,000 to get everything out of it... It would really be a silly to expense only Rs.7000 and not only hope but also demand for Rs.15000 experience... I would rather say, well done Karbonn for such a good phone at such a reasonable price...
