Today I Am Share My Personal Experience With JioFi 4 Wifi Router To Everyone. Recently I Have Purchased This Product, But I Am Not Happy With Us, Because They Are Give Me Very Slow Internet Speed. This Hotspot Launched By Reliance Jio, They Company Promised To Me This Hotspot Speed Is 150 Mbps, But These Hotspot Speed Is Only 1-5 Mbps. They Are Cheat Me, And This Product Battery BackUp Also Are Cheap. Then I’m Complain Jio Customer Care, They Are Say Me Sometimes Network Problem, But Internet Speed Is Fix Problem Always And Don’t Resolved Customer Support Care. Thank You
