When Reliance Jio first conceptualized and rolled out Jio 4G Preview Offer, nobody thought the demand would exceed supply by such staggering numbers.

We understand how annoying it can get when you so badly wish to use the SIM but haven’t been able to do so because you simply cannot get the network signal!

How To Fix Reliance Jio 4G SIM ‘No Network Signal’ Issue

Before we head to the solutions that address this problem, we need to be absolutely sure that you are aware of the most common reasons why you are facing this issue –

1. Number one on the list is simple yet profound – your number hasn’t yet been tele-verified. Sounds silly? Yes, it does. But without tele-verification, you simply cannot expect to get network signal. Be absolutely sure that you have completed the tele-verification process by dialing 1800-8901-977 and checking the current status. If your number hasn’t gone past the tele-verification stage, you will hear a message that says your number isn’t ready for tele-verification and that you will receive a tele-verification message when ready.

2. The next most important reason is that your phone probably doesn’t support 4G. If your phone is 4G compatible, make sure it supports Reliance Jio Signal bands – 800MHz, 1800MHz and 2300 MHz. Just head to any of the websites that display your phone specifications and ensure that these bands are supported by your 4G device.

3. The third reason could be that your LTE settings are incorrect. Ensure that you have the right settings to receive 4G network signal. Head to Settings -> Mobile Networks -> Preferred Network Type. Choose LTE. 

4. And last but not the least, make sure that you have the 4G SIM inserted into the SIM slot that actually supports 4G. Remember that most Dual SIM phones come with two slots – one that supports 4G and the other that supports 3G/2G.

Once you are absolutely sure that you have taken care of all the above common reasons that can result in “No Network Signal” issue, read on to try other solutions that address this problem.

Solution 0: Try the tried-and-tested solution – “Restart”

There’s a reason that we have named this “Solution 0”. And the reason is that a simple restart fixes most electronics problems most of the times! And mobile networks aren’t any different. Just make sure you have the SIM inserted and restart your device. Now check to see if your phone can detect the signal.

If this solution didn’t help, continue to read on.

Solution 1: Ping-ON Test

One of the methods to ensure that your network signal is up and running is the Ping-On Test. This must be done carefully, so follow these steps with caution –

  • Enter code *#*#4636#*# using Dial pad
  • You will see ‘Phone Info‘ option. Click on this.
  • Then tap on Run Ping Test. Make sure Radio option is ‘ON’.
  • Reboot Device.

Rebooting the device after the ping on test will most probably fix the issue. If not, head to solution 2.

Solution 2: Ensure the SIM is in right slot

As we have already mentioned, SIM being placed in the incorrect location can cause this issue. So just be sure you have placed the SIM in the right slot – by right slot we mean the slot which actually supports 4G – switch off your device, remove the SIM and place it again with due care in the right slot. Restart the device and check to see if the problem persists.

Solution 3: Time for Manual Intervention

Sometimes, the problem can be fixed by manually setting up your network. To do this, head to Settings -> More Networks -> Mobile Networks. Ensure that your SIM is on ‘WCDMA‘ (common mode for 3G and 4G).

Solution 4: Fix for “Emergency Calls Only” Issue

This isn’t something that’s specific to Reliance Jio SIM alone. Phones with other network SIMs also face the similar issue when not registered on the network. Basically, when you try to dial a number, all you see on the screen is the annoying message “Not Registered on Network”. Or said another way, you can only place emergency calls. To fix this issue, follow these steps –

  • First thing to do is to turn off mobile data.
  • Head to Settings -> Mobile Networks -> Jio 4G -> Cellular Networks.
  • If you have already turned off mobile data, the phone searches for available cellular networks and shows you the list of cellular networks to choose from.
  • Select Jio 4G.

You should now see a notification that says “Registered on Network“. Once registered on the network you can continue to use the SIM without any issues!

Most of the times, one of the solutions posted above definitely fixes the problem. If you still have issues, it could be that the problem is specific to your device. Let us know the nature of the problem in the comments section and we will do our best to help you fix it!
