First of all thank to ambhani for this type of services and offers in this SIM.
Friends I think someone are voried about the voice calling, all 4g phones are not supported to voice call because you're handset does not have 4g Volte service broadband it is inbuilt. Which is coming from the handset manufacturer
and those handset does not have Volte service that type of handset also capable to make voice call simply by just downloading the Jio 4gVoice application it will help to make voice call
According to my opinion jio is the best network, data plane, and net speed. it is better than airtel 4g. And also jio did not have any separate network tower it just submerged with the other networks
