    • By HARPAL SINGH September 5, 2016

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

    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.

    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.
