My friend has Z2 plus and he faces the same issue.. it might be Nokia issue or might be Jio issue.. but if you are able to call someone ..it can not be a software or volte issue.. its the carrier issue then which has forced disabled your short calls... or Jio does not support Nokia 7 plus fully... if jio to jio mobile has an issue... try resetting the phone after backing up the data...
I am facing the same issue on my Nokia 8. When I call Jio customer care from my phone the call gets disconnected. I am able to make calls to all other numbers. If I put my sim in some other phone, then I can call Jio customer care. I also got it flashed from a near by Nokia care center still the same issue is there. Talked to Jio they say tried to trace the problem and found that my handset is not allowing the call to be placed. Please help
Not for me. Just tried it again. I am using Nokia 8. Looks like they just fixed it for Nokia 7 plus
i called the numbers from my jio sim and they are working
