Have some queried about Jio sim. Some of these may be noobish or already posted, but its becoming difficult to browse so many threads.
The Sim is from the new all handset offer
1) Once the Sim has been inserted into one mobile, can it be used on a second device i.e. will the unlimited data stay
2) Can it be used on 3g device, in 3g mode
3) If phone does not have VoLTE, we have to use JioJoin to make calls??
If yes, do these calls require data to be on which means we cant make calls when offline
