I was using jio sim which was a postpaid sim and it was working fine in Jio4GVoice App, i was able to make call from my handset which is LTE. But on 16th March 2017 i converted jio sim from postpaid to prepaid. After 4 or 5 hours i got a message from jio for tele-verification. then i call to 1800-890-1977 from other vendor sim, and i successfully activate the data service in my jio sim and i can access the internet from jio prepaid sim which was i converted.
Then i tried to call 1977 for voice service activation from Jio4GVoice App but it was showing Provisioning Configuration update required alert and Jio4GVoice app always in offline mode. I have updated my handset also but it was not working. i have uninstalled Jio4GVoice app and installed again but it is showing same error. I have switched off my mobile and switched on again but it is showing same problem. So can you please help me out from this ? Handset Details Lenovo vibe k5 plus – 4G LTE
