I have one reliance sim.reliance tower is very bad except when you are outside you will not get a single tower.when I am in my house my reliance does not work.i also have internet on my sim but their is also very slow.their service is also very bad.after being on line for 15min they pick up the phone. I will never use reliance sim again as it do not work at home so it is useless for me.but the charges of reliance are less than other companies.
