Free charge is far better then Pay TM. I’ve downloaded pay TM before in my android phone but later onward I’ve started facing some problems like my Recharge is done after 2, 3 hours, bill is in waiting & money is been debited from my account. So later on I’ve downloaded free charge and it is just perfect I’ve got my phone recharged within seconds. I am very happy with the service. so its my recommendation to use free charge then pay TM.
