What Downdetector Shows
According to Downdetector data, there are currently no reported widespread outages affecting Jio users—mobile internet, broadband, and total blackout reports are all at typical daily levels, indicating any issues are likely local or isolated (downdetector.in).
Recent Notable Outages
- On June 16 2025, Kerala faced a severe disruption: over 12,000 users experienced mobile data, voice, and fiber outages. Services were restored later that day.
- Around June 19 2025, sporadic service disruptions were reported in cities like Ahmedabad, Mumbai, Bengaluru, Kolkata, Delhi, and Nagpur—though these did not rise to large-scale outage levels.
Why You’re Still Offline
- Localized issue: If Downdetector isn’t showing a spike, your area may be experiencing a transient glitch.
- SIM or phone problem: Since changing phones didn’t help, the issue might be with the SIM itself or account configuration.
Popular Fix: APN Configuration
A common fix involves updating your Access Point Name (APN):
- Go to Mobile Network settings → Access Point Names
- You can reset to default settings or manually set JioNet, which is the standard APN
- Some users have also tried alternate APNs—like
jiodataorloop—with success.
Troubleshooting Checklist

|---|---|---|
| 1. Toggle Airplane Mode | Enable, wait 10 sec, disable | Forces network re-registration |
| 2. Restart your phone | — | Clears software/network interruptions |
| 3. Switch SIM to another phone | — | Identifies phone vs SIM issue |
| 4. Replace SIM | Visit Jio center (~₹25) | Fixes SIM card corruption |
| 5. Reset/change APN | Use JioNet or alternate | Restores data connectivity |
| 6. Contact Jio support | Via app or call 199 | Escalates local network investigation |
If Nothing Works
- Try Wi‑Fi calling or use nearby Wi-Fi.
- Consider porting to another provider (e.g., Airtel or VI) if the issue persists.
- Track at-home outages via Downdetector for region-wide alerts.
- Monitor Jio’s support updates, as issues may be fixed silently on the backend.
Final Thoughts
You’ve already taken excellent steps: reboots, Airplane Mode toggles, and SIM swaps. Since the issue remains unresolved, the problem is likely a local network glitch or a faulty SIM card. Next steps: replace the SIM, refresh your APN, and file a grievance with Jio support. Keep tracking Downdetector—any uptick in reports could indicate a broader issue.
