How to use a Jio 4G SIM in a 3G Android Smartphone

Jio LogoMobile Network Operators in India have always gone head to head as to who has the best technology, and they’re constantly releasing newer and newer ways to enjoy your mobile. As the internet grows and grows, so does the need for faster internet on the go, so the big telecom companies look towards 4G networks over 3G that has been used in the past. But there is one trailblazing company that solely relies on 4G and does not transmit any signal in older bands: Jio-Reliance Communications.

They’ve released the Reliance Jio 4G SIM and the mobile space in India has been abuzz in trying it out. However, not all phones are up to spec when it comes to running 4G, most mobiles in people’s pockets can only transmit and receive in 3G at most. If you have a 3G phone and you insert the 4G Jio SIM card into it, the signal bars will show empty. But don’t fret, there are a couple of workarounds that either trick your 3G Phone into thinking that it can operate with 4G or simply unlock the 4G option if it’s not available. With these tricks, you can still take advantage of the latest network technology, even with a phone that looks like it can’t use a 4G SIM.

We’ll let you know How to use Jio SIM in 3G phone in a short bit but before that, there are some prerequisites that we need to find out about our phone before we proceed. We might need to know what version of Android we have running right now and what kind of chipset (processor) is inside of our 3G Smartphone. To find this information follow these instructions:

  1. Go to your Device Settings (it looks like a gear most of the time)
  2. Scroll down to the bottom and find About Phone
  3. From here, depending on the phone that you have, you might need to click on Software Info
  4. Get a pen and write down the Version and the Processor/Chipset of your Phone.

If above steps don’t show you Processor/Chipset, download CPU-Z app from Google playstore. It shows all the information about your device and should show processor too.

CPU-Z App

Alright! With that piece of information in your hand, you can determine if your phone is MediaTek or Qualcomm. For example, it’s a MediaTek if the Chipset uses the format MTxxxx where the x’s are numbers. Check and follow the steps below based on what kind of device you have.

Here are the different methods on how to use Jio SIM in 3G Phone:

Note: We are not responsible if anything goes wrong. Proceed with caution. 

MediaTek Devices

For this trick to work, you need the following:

  • Android KitKat 4.4 or above
  • MediaTek Chipset
  • MTK Engineering Mode App – this will allow you to enter a special menu called service mode. See the instructions below on where to download this app.

Let’s get onto the steps on how to get into service mode and enable 4G on your phone:

  1. Remove the 4G Jio SIM card from your phone, we’ll let you know when to put it back in
  2. Download and install the MTK Engineering Mode on your 3G Phone by clicking on this link <https://play.google.com/store/apps/details?id=com.themonsterit.EngineerStarter&hl=en>
  3. Open the MTK Engineering Mode App and click on MTK Settings
  4. Select the Preferred Network option to see a list of available network modes to you
  5. From here, just select the 4G LTE/WCDMA/GSM as your network mode
  6. Save your new settings and turn your phone off
  7. While your phone is off, insert the 4G Jio SIM (Make sure that you’ve already activated it), and power your phone on
  8. Wait for a couple of minutes for your phone to scan for the networks
  9. Viola! Network bars should be showing on your phone and you’re now connected to the Jio network
  10. Enjoy!

Note: What we did here is we tricked our phone that it can transmit and receive in 4G but it will still use 3G since it’s not a True 4G phone so you can expect to have 3G speeds.

Qualcomm Devices

This trick is unconfirmed if it works on all Qualcomm Devices but reports say that it works on some. If it’s not working on your device, you can try other methods on this list. Let’s hope it works on your device! You’ll need the following:

  • Android Version 1.6 and up
  • Qualcomm or Qualcomm Snapdragon Chipset
  • Shortcut Master (Lite) App – This app searches your phone for any hidden menus, and it might reveal the Service Mode on your phone to modify your network mode

Here are the steps on how to use Jio SIM in 3G Phone if you have a Qualcomm device:

  1. Remove the 4G Jio SIM card from your phone, we’ll let you know when to put it back in
  2. Download and install the Shortcut Master (Lite) App on your 3G Phone by clicking on this link <https://play.google.com/store/apps/details?id=org.vndnguyen.shortcutmaster.lite&hl=en>
  3. Open the Shortcut Master App and search for either of the keywords, Service Menu or Engineering Mode. You might get better results if you filter by System App.
  4. Once you’ve found Engineering Mode, open it and select Change LTE Bands. Alternatively, if you couldn’t find Engineering Mode, go to your phone’s dialer and dial *#2263# and it should be able to pull up the same thing
  5. Depending on the Phone that you have, it might ask you what SIM Card you want to change the settings on. Just select SIM 1 for now.
  6. On the next menu, look for LTE Band Preference or LTE Band Selection
  7. You’ll get a list of different LTE Bands, but what you need to press is Band 40 or B40. You might need to click on Next Page if you don’t see Band 40
  8. Turn off your Phone, insert the Jio SIM card in SIM 1 then Power it on. It might take a couple of minutes to get the signal bars to appear on your phone.
  9. Viola! Network bars should be showing on your phone and you’re now connected to the Jio network
  10. Enjoy!

Stock Android

This trick takes advantage of Stock Android devices. What is Stock Android? If the mobile phone that you’re using does not have any fancy UI or customized features that were installed by the manufacturer, most likely you’re using a Stock Android phone and this method might work for you!

  2. Open your phone’s Dialer and dial *#*#4636#*#* and once you’ve dialed that number, you don’t need to press anything; it should automatically open the Service Menu. If it doesn’t pull anything up, then unfortunately, this trick will not work on your phone.
  3. The Service Menu should open. Scroll down and look for Phone Information
  4. Select Preferred Network Type
  5. Choose the option that says LTE/WCDMA/GSM or 4G
