It is the average networking system I see. Its mobile network quality is so good . Where I go network is ok. But its call chargers promo charges is so costly. And its customer service is bad because vpn services are activeted automatically and charges to be cut the account. And when you call the customer care then the said - you activate this service by send a message or any phone call.
So please fix this problem.
And its 4g network is not good , and 4g speed is not good in bengal. Mobile network is not found fully.
