The lyf phones comes with the jio sim its the only advantage.If you want to use it as your primary phone then this is not for you.It can support 4g the only pro of this phone .The build quality is good compared to its rivals on this price range .This phone comes with 512mb of ram which is very less for heavy use.The main con is it does not support play store.If you want a jio sim easily then this is good you can use it as a portable hotspot and secondary phone.Overall buy it as a hotspot.
