I am very old customer reliance gsm from purchasing to till date network has been demolish day by day If you 10 km away from cant get tower or very weak tower, 2nd problem which are coming me regularly call drop while talking sudden call disonnect and some times balance deduct without you any subcibtion of any sevice that service subcribe automatically so If you are planning new new sim don’t pusrchase it. If yiu want purchase jio so you may get with lots of service but at present realince gsm service has been very poor.
