I am using Reliance jio over more than 15 months. In starting it is free but now a day it charges money but still Jio plan is quite cheaper than other any telecom plan.
The bigest problem with this is that its network fail to zero when I set data on other sim.
For using jio sim we must have to set our data mode on jio sim otherwise its network do not support. This makes me very upset and disapointed.
It also have a too much network problem due to which internet speed is decreases and call is also fail many time.
If your area is under jio network then it is best option for you to use this sim than any other sim because it is cheaper than other.
If you are looking for very high speed data then it is not good . It is only good for personal use not for commercial.
