This is a brand which came in chat among public very strongly which emerged in people very powerfully. Why? Because of its call and Internet plan? All say YES but if we think about the future conditions of its current users. Its very bad .this is same as when somebody offer us cigarette first time without any cost we smoke second time without any cost we smoke and when time pass we have been addicted to this now we must have purchase this from shop, so here is also the same scenario , this company making us addictive of the Internet with 4G speed when its free plan will expire at that time we will get addicted and we have to recharge its plan unwillingly . this is what I think but on other hand this is also a matter of promotion without this free offer this company was not able to make such a customer base. And if we talk about network coverage this was very good in starting but now .everybody knows about this and the quality of call. what do you think about this make me comments . if u liked or hate my review .
