Bought JioFi yesterday(4Aug’16 @5PM) and got activation msg today(5thAug) @2:30PM.
Activation was easy just call 18008901977 from any mobile and answer the queries.
HP device was NOT billed on my name still I got Jio SIM, so its a non issue.
Device is good very small and light. Wifi Range is ok for medium house. Signal strength is good in my place.
Device supports all 3 bands of 4G: 3,5, and 40.
Homepage:192.168.1.1 or 192.168.225.1
You can change SSID, password and other details after login.
Pressing power+WPS buttons simultaneously for 5 secs will reset the device to factory defaults.
You can make calls also from VoLTE mobile handset connected to Jiofi device. I have not tried yet.
Speed is quite good I am getting above 10mbps for downloads, reaching max of 25mbps.
Tried with torrents and got 20+mbps stable. Strangely speed test websites show only 3-4 mbps in their results.
Most probably this SIM may work on any mobile with VoLTE(as per retailer) will update once checked.
