I know how frustrating it can be when your Jio internet suddenly stops working, even though everything seems fine. If your mobile data isn’t connecting, websites aren’t loading, or speeds are painfully slow, chances are your APN settings are not working properly.
APN (Access Point Name) settings are the key to connecting your phone to Jio’s network for mobile data. If they’re misconfigured or reset incorrectly, you’ll experience no internet, frequent disconnections, or speed throttling.
Quick Summary
If your Jio APN settings aren’t working, try these fixes:
- Reset APN to default and re-enter manually.
- Switch to 4G/5G LTE mode (Jio does not support 3G/2G).
- Restart your phone or toggle Airplane Mode.
- Remove and reinsert your SIM card.
- Check your data balance (*333#) and ensure your plan is active.
- Reset network settings (Android/iPhone).
- Try an alternate APN like ‘ims’.
- Check for carrier settings updates.
- Test your SIM in another device to rule out phone issues.
- Check real-time Jio network outages on Downdetector.
Let me walk you through the details and how I fixed mine.
Why Jio APN Settings May Not Work
Before we dive into solutions, let’s break down the most common reasons why Jio’s APN settings stop working:
1. Incorrect APN Configuration
Jio’s APN settings must be set correctly for data to work. If even a single field is incorrect (e.g., APN name, protocol type, or authentication method), you won’t be able to access the internet.
2. Network Issues & Outages
Sometimes, the problem isn’t on your end. Jio’s servers may be down, or network congestion can disrupt APN functionality. Checking Jio Downdetector for real-time status can confirm if it’s a broader issue.
3. SIM Card Problems
A damaged, improperly inserted, or inactive SIM can prevent Jio’s APN settings from being recognized. If your SIM isn’t registered properly, data services won’t work.
4. Device Compatibility
Not all phones support Jio’s LTE-only network. If your phone doesn’t support VoLTE (Voice over LTE), you may experience network connectivity problems.
5. Software Bugs & OS Updates
A recent software update may have reset your APN settings or caused conflicts. Jio’s carrier settings may also require an update to function correctly.
6. Data Plan Activation Issues
If your Jio data plan is expired or hasn’t been activated, APN settings will seem faulty, even if they’re correct. Always check your balance and plan status before troubleshooting further.
How to Fix Jio APN Settings Issues
If you’re facing Jio APN not working, follow these steps to restore your internet connection:
1. Verify & Reset APN Settings
Check Existing APN Settings
- Open Settings → Network & Internet → Mobile Network.
- Tap on Access Point Names (APN).
- Ensure that Jio APN is selected.
Reset to Default APN
- Tap the three-dot menu → Reset to Default.
- This will restore Jio’s original settings and fix minor misconfigurations.
Manually Re-Enter Jio APN
If resetting doesn’t work, manually enter the Jio settings:
| Field | Value |
|---|---|
| Name | Jio |
| APN | jionet |
| Proxy | Not set |
| Port | Not set |
| Username | Not set |
| Password | Not set |
| Server | Not set |
| MMSC | Not set |
| MMS proxy | Not set |
| MMS port | Not set |
| MCC | 405 |
| MNC | 857 / 866 / 874 (varies per region) |
| Authentication type | None |
| APN Type | Default |
| APN Protocol | IPv4/IPv6 |
| Bearer | LTE |
2. Restart Your Phone & Toggle Airplane Mode
- Turn Airplane Mode ON for 30 seconds, then turn it OFF.
- Restart your phone and check if mobile data starts working.
3. Check Network Mode (4G, 5G Only)
Jio does not support 2G/3G, so your phone must be in LTE mode.
- Go to Settings → Mobile Network.
- Select Preferred Network Type → 4G/5G LTE.
- Restart your device.
- If using Jio 5G, select 5G SA mode.
4. Reinsert the SIM Card
- Turn off your phone.
- Remove the Jio SIM and wait 2 minutes.
- Insert the SIM back and turn your phone on.
5. Use Dialer Code to Force LTE
- Dial
*#*#4636#*#*. - Select Phone Information → Set LTE Only Mode.
6. Modify DNS Settings (for better speed)
- Google DNS:
8.8.8.8/8.8.4.4 - Cloudflare DNS:
1.1.1.1/1.0.0.1
7. Test Jio SIM on Another Device
If none of the fixes work, insert your Jio SIM into a different phone. If it works there, your device might be the problem, and you may need a factory reset.

Conclusion
If your Jio APN settings aren’t working, start with the quick fixes like resetting APN, checking network mode, and reinserting your SIM. If that doesn’t work, move to advanced fixes like using an alternate APN or updating carrier settings.
If nothing helps, the problem could be device-specific or a Jio network issue—contact Jio support for further assistance.
