I have been using this sim from 4 months, and this sim is working fine in other phones.

I have swapped with other jio sim, They too are not working. But Airtel 4G is working.Jio sims work only in the LTE mode but need the VoLTE option turned on, which is somewhere in side the dual sim or mobile networks settings of the mobile phone to make calls. Without VoLTE turned on for the sim, the Jio will only connect to the internet but won't make voice calls. Airtel sims work in both the LTE and GSM modes so when VoLTE is turned off, they make calls via the GSM/3G network. So if a recent bad OTA update on yr phone or some internal siftware issue has permanently turned off the VoLTE support on yr device, you can still download the Jio calls app for the non-VoLTE phones from the Playstore and make use of that for yr Jio sim, until you can figure out a way to enable the VoLTE support on yr mobile device.
I have the exact same problem on my Nokia 7.1, for the past few days. However i have found that my Wi-Fi calls are unhindered. I can't even send or receive sms neither calls ita pretty big pain in the **** though 😒😏
WASTE Service by Nokia. Nokia Disappointing People. Nokia don't have shame at all. Such a waste Service.
Do you get the VoLTE icon in your notifications area? Jio can only offer calls and texting services when VoLTE works. Also, check that Enhanced 4G LTE mode is enabled in Network Settings.
Same thing happened to me , i swapped my jio sim to SIM2 and it started working , i was able to see VOLTE Symbol and everything working fine , i tried again swapping sim to SIM 1 and now i do not have any issue. Everything working fine.
