How to Switch / Change 2G to 3G 4G LTE only Network mode in Android Phone

Android phones nowadays come with great connectivity options, like 3G and 4G LTE. The 3G and 4G LTE network offers faster internet data speeds than the 2G, GPRS or EDGE. If you subscribed to 4G LTE or 3G internet Data plan it is very vital and beneficial to use it in LTE, HSPA+ or WCDMA only as Preferred Network Internet speeds. In some cases to avoid heavy data charges you might prefer to go with 2G GPRS network mode only. If you have 4G phone below methods will help you to switch between different network modes. But if you have 3G smartphone and want to use 4G LTE SIM card on 3G phone you can check last two methods / tricks but it is not possible to use 4G LTE only network operator SIM on 3G or 2G phone. You can buy JIOFI and can make HD calls and use 4G data speed on any 3G or 2G supported phone over Wi-Fi. Otherwise you need to upgrade to LTE / VOLTE capable phone.

Change 2G to 3G 4G LTE only network Preferred mode in Android Phone

Android operating system offers the variety of options to choose the best Preferred network  according to your comfort. We found that in some Dual SIM smartphones users faces difficulty in selecting their desired preferred network mode. Below are two solutions, with which you can Toogle Switch or Change from 2G to 3G or force 4G LTE only mode or vice-versa. Many are trying to switch to 4G LTE so that they can enjoy Reliance JIO 4G VOLTE free calling and unlimited data offer on mobile phones. Now Airtel 4G, Vodafone, Idea, BSNL unlimited plan (3G without usage restriction) and many other operators has also launched low price data plans, but mostly with Data cap / speed restriction.

  8. Choose the best Suited Option for according to you preferences

You can also select Combination of 2G + 3G ( Will automatically choose 2G network when 3G is not available). Many users found that after selecting 4G LTE or 2G Network the status bar shows no network signal. This could be due to several reasons, diagnose it in following ways:

  • Make sure 3G or 4G LTE network signal are available in your area
  • Go to Network Operators (you will find it in Above solution at Step 5)
  • And Touch on “Select Automatically” or “Search Network” to select Network Manually

If the Internet on the phone is not working make sure you have configured correct APN Internet Settings. Solution 2:

    i am not getting signals on my jio4g sim, yesterday when i insert the sim it was showing but now it is showing no service.

    • By HARPAL SINGH September 5, 2016

      It might be due to SIM not activated yet or due to low signal strength.

    • By HARPAL SINGH September 20, 2016

      No. as it doesn’t have the required hardware for 4g lte.

  8. By JanOve September 25, 2016

    plz help me in this regard

    • By HARPAL SINGH October 17, 2016

      You can try App install Method, mentioned in the post. That will allow you to switch to only one network.

  11. By Raveesh October 23, 2016

    hi sir, mine is mmx a117. I want to use jio sim in this phone. I have installed mtk eng.mode app. in mtk settings it shows GSM/WCDMA/LTE in the preferred network selection. But when it select it and return to revious menu it rolls back to wcdma mode only. There is no provision for saving the settings. Please guide me

    • By HARPAL SINGH October 23, 2016

      The reason is because the phone doesn’t have 4G LTE Hardware.

      • By kiran December 9, 2016

        Actually in ussd code method it is said to open “key input” and enter “0000” so in this context what is “key input”? is it in dialer itself or anything else.
        And in another method of shortcut lite app , in engineering mode my phone(lenovo A6000 plus) does not have any options to change bands.
        So do u have any solutions to this.

  12. By Anshu December 14, 2016

    I have tried both WCDMA And LTE but it is not showing network bars
    What can i do

    • By HARPAL SINGH December 14, 2016

      It could be due to two reasons either the SIM is not 3G / 4G Lte enabled or the supported SIM bands are not compatible with your phone. OR may be due to low network signal.

    How to convert vivo y11 in to 4g(lte)

    • By HARPAL SINGH December 15, 2016

      It has 3G hardware so 4G VOLTE SIM can not run on this. As this is more related to hardware so there is no way to convert it to 4G without changing its hardware components.

    status bar shows no network when I choose 3G/4G network what procedure should I use. And my fone ux samsung galaxy note 2 T- mobile fone.

    • By HARPAL SINGH December 21, 2016

      Either the SIM is not 3G/ 4G compatible or the SIM bands are not compatible with your phone.

  15. By Jack Roberts January 6, 2017

    I recently bought a Samsung Galaxy J7(2016)Dual Sim phone. The reason I did it was so I could use only one phone for my business line and one for my personal line. The problem I have is that AT&T recently discontinued the use of GSM and my phone says “two sim cards cannot use the same 4G or 3G at the same time. The other card will be changed to use 2G”, when tried to switch the second line over to 3G or 4G. I read your article and am wondering if this would be a fix for my phone, specifically by using the USSD Code, or if there’s any other workaround.

    • By HARPAL SINGH January 7, 2017

      That setting is set default by the OEM (Samsung), so it cannot be altered without software updates.

      • By Jack Roberts January 8, 2017

        Thank you for the response. Does Samsung offer such updates? I did a search and didn’t find one. I’m not convinced they would offer it, since it might dissuade a customer from purchasing a newer model phone. I was wondering whether one sim card could be set up to use 4g only and one set to 3g only by using the USSD Code method. My phone seems to lump those networks together. If each could be set up as dedicated to one network only I’m wondering if perhaps that would solve my problem. That way the sim cards would not share a network if one was one was on 3g and the other on 4g.

    I’m using samsung galaxy note 3 neo MODEL N7505 version 4.4.2 please help me jio 4G sim support

    • By HARPAL SINGH February 6, 2017

      Only the SM-N7505 model will support 4G sim. The SM-N750 is not 4G SIM compatible.

  17. By jahid April 4, 2017

    I brought oppo f1 from Bangladesh. Now i am staying in india.I haven’t 4G option in my phone.But when i entered into jio sim in my phone,then Enhance 4G(LTE) mode has shown.but no network signal shows.I tried this tricks but there any way to use 4G in my phone?

    • By HARPAL SINGH April 4, 2017

      The phone is compatible with JIO sim. Make sure the SIM is activated and there is enough signal strength in the area you are using it. Try to check the SIM in other 4G phone, see it shows LTE signals.

  18. By Muwanga Nasif April 7, 2017

    Hi sir, i have an Huawei but the prefered network mode is disabled . i have tried the other options but all failed. the phone can support 4G network but its only using 2G! what can i do?

    • By HARPAL SINGH April 7, 2017

      Hi Nasif,
      See, if you Select 4G / 3G Preferred mode it means that the Phone will be in 4G /3G mode if respective signals will be there. Otherwise if there is no 3G / 4G signals are there then it will automatically choose the 2G / 3G vica versa mode.

    Dear Harpal Singh Jee

    I have Le 2 phone. Am working in SIgapore for 6 months. And have SIM1 as 4G Starhub SIm card. And SIM2 from Airtel India. It was working fine till 31-March. Singapore has shutdown the 2G network from 31-March. I understand that the Le2 dual sim phone only works on 4G & 2G networks. If one SIM is alreday 4G, the other becomes 2G automatically. Is there any solution (patch, engineering mode) to make SIM1 as 4G & SIM2 as 3G. Pls suggest, this will solve my problem. As I dont want to buy another phone because of 6 months time period.

    Rgds. Tuteja

    • By HARPAL SINGH April 22, 2017

      This configuration is easy and less battery draining so most of the OEM apply this to their firmware. It is not possible without tweaking the firmware and might require additional hardware (tx – rx). Sorry but currently we don’t have any patch to make use of 4G on both SIM simultaneously or 4G + 3G at the same time on dual SIM phone.

    • By HARPAL SINGH April 28, 2017

      the reason is behind this is because there would be less 3G / 4g signals

    • By HARPAL SINGH May 6, 2017

      This is due to low 3G signals, wherever there is not enough 3G signals phone will automatically switch to 2G or the network mode with good signals.

    • By HARPAL SINGH June 9, 2017

      If you have selected 3G as preferred network but still getting 2G signal, that is usually due to low 3G signals. Whenever phone don’t get enough 3G / 4G signal it switches to 2G.
