Fix Jio SIM for “No Service, Emergency Calls Only” (Not Working)

Tips to fix if a Jio SIM card is not working or showing No service, Emergency calls only and not showing any network or signal 4G phone.

Reliance Industries came up with a bang in the telecom sector giving a sheer setback to its peers. The offers, plans and freebies offered by the Jio can make anyone have goosebumps. After its so-called Beta testing phase and preview phase, the Jio is now in stores as commercial launch.

It offers Voice over LTE (VoLTE), high-speed data and other quality services. But with such a wide scale launch there will always be issues with calls, call quality, call drop and network stability.

Reliance Jio Infocomm is said to be world’s biggest startup with over Rs. 1.5 Lakh Crore invested in this mega project. The company has acquired rights for 4G services in all circles of the country.

Of course, it is too early to talk about the success of the project but for sure Jio has created ripples across the telecom sector of this country.

If you have bought a Jio SIM and if it is not working or you are facing any technical glitch like no network signal, internet not working then here are some tips to fix the problem.

Fix All the Network/Signal Issues on Jio SIM

Issue 1. SIM Recognised but No Network

If your Jio SIM is recognised but you cannot see any network signal then following steps will fix the problem.

Set Jio SIM as Default for Mobile Data

If your Jio SIM is not showing any signals then you need to first set Jio Digital as your default SIM for internet mobile data.

To do so simply goto;

Settings → SIM Cards/SIM Management/Edit SIM → Mobile data/Internet → Select Jio Network → Set Network as LTE/4G (Read Below)

⇒ Set Network as LTE/4G

Once the Jio SIM is selected you need to set Jio as LTE or 4G. To do so –

Step 1. Open Android Settings

Step 2. Under Wireless and Network, tap on More

Step 3. Select Mobile Networks/Cellular Networks

Step 4. Select your SIM card. ( For dual SIM devices)

Step 5. Then check for the option called Network Mode or Preferred network type and click it.

Step 6. You will find three options called GSM only, WCDMA only and 4G/LTE.

Step 7. Now select option of LTE or 4G

Step 8. Restart your Phone.

You will see your SIM working with Data.

Step 3. Click on Phone Info

Step 4. Tap on Run Ping Test

Step 5. Scroll down and under Set Preferred Network Type as LTE/GSM auto (PRL)

Step 6. Now Turn OFF Radio & then Turn ON

Step 6. Reboot the phone. Done!

Set APN for Jio SIM

If APN is not automatically set then manually change the setting and set a Jio APN. Settings > Mobile Networks > Access Point Names.


Watch Video for more information on APN settings

You can also manually select the network operator by going to Settings > Mobile Networks > Network Operators.

Issue 2. If SIM Recognised & Network Available but No Data

Using MyJio App

If Jio SIM is recognised and the network is also available but data is not working then;

Just simply open the MyJio App and click on first option i.e manage Jio Account and simply click skip sign-in. You can access the unlimited data.

Enter flight mode

Flight mode is the best choice when you wish to have a mini SIM switch off.

When you turn ON the flight mode, the device performs a mini switch OFF cutting the SIM cards from power and then after few seconds when you turn OFF the flight mode, the device will recognise the SIM networks eliminating any signal instability. The internet data will work fine.

Issue 3. If SIM is Not Recognised

Check for Activation

Make sure your SIM is activated. After you have bought the SIM, you will first receive the SMS of document verification on your alternative number followed by another SMS regarding Tela-Verification within a  couple of hours or days.

Ones its done you can insert the SIM in your mobile and enjoy the services. You can contact the Jio on their customer support.

You can call Jio – 1800-88-99999 (Other Operators)

For Jio SIM users – 199 (From Jio SIM)

Reliance Digital – 1800-103-1044

Enable Accessibility Permission

This solution can also fix the issue if you do not see any network;

Download Jio Security from Google Play.

Open the App and grant all the permissions prompted. Scan the phone and change all the apps to trusted if it shows risk with some Apps.

  • Turn ON your Location
  • Settings –> Accessibility–> Jio Security –> ON

Check the Device Compatibility

Make sure the device is 4G enabled and supports Band 40 (For some states Band 3 and Band 5) for which Jio offers its internet.

If your device doesn’t support the Band owned by Reliance in your state then 4G will not work on your device. Also, remember to use SIM Slot 1 for Jio SIM to catch the network.

Issue 4. If SIM is Working but Calls Not Working

Make sure your devices support voice over LTE. If it does then just download the JioJoin App from Google Play Store, log in with your Id and password and make calls over voice. This will surely fix the problem.

Here is also a video guide with some extra tips –

Other Miscellaneous Fix:

Flight mode is the best choice when you wish to have a mini switch off. When flight mode is ON it is like a mini switch OFF  it will disable the SIM cards from power and then after few seconds on turning OFF the flight mode. The device will recognise the SIM networks and hence will show the network.

This if you are facing any unstable network can help you fix the issues on Jio SIM.

Conclusion: With the above methods you can fix all the SIM networks issues on Jio. Check the SIM card for other devices. If after doing everything it doesn’t work for your smartphone then there are some software or hardware incompatibility on your phone.
