I m using relince jio but its service is not like that showed in advertisment , frist problem is that it not get covrage automatically as soon as we reach in its covrage area , if we want to get network covrage than we have to restart our mobile .i am not saying that this type problem is in all mobile but I am sharing my view and exprince , when it get network covrage then its speed is not like a 4g sim .some time net will stop and some time start .maximum speed is as I show 120 to 130 kbps.i think this speed is not like 4g speed , I have seen better speed in my airtel 3g sim , so it need to improve.
