This phone has a lot of disadvantages first of all you cannot open the back cover of this phone and so the battery.if the battery gets damaged you will be in serious trouble as you will not be able to remove it.how will you replace it, .secondly this phone has a very disadvantage that in it you can either for two sims of one sim and one sd card.it does not gives the feature of dual sim as well as memory slot.the memory slot is same as for the sim.so this is again a great demerit.Along with that if while inserting the sim you bymistakely you put it wrongly then the whole phone will get damaged so I do not recommend anyone to buy this phone.
