To Become a Professional Esports player

I am Soumen Sadhukhan. I am 22 years old from Kolkata, India. I want to start my Esports career as a Esports player. I practice a lot in day and night. But my mobile is not good enough to play in competetative level. So, my dream is like to be fade away. Please help to buy a device. I don't have enough money to buy a good device. I promise everyone of you , I will be a professional player and touch my dream to represent India in global level as a Esports player. Thanks a lot, for your love and support.
