Android phones nowadays come with great connectivity options, like 3G and 4G LTE. The 3G and 4G LTE network mode offers faster internet data speeds than the 2G, GPRS or EDGE. If you subscribed to 4G LTE or 3G Internet Data plan from BSNL, JIO, Airtel, Idea, or Vodafone it is very vital and beneficial to use it in 4G LTE only, HSPA+ or WCDMA 3G only as Preferred Network Type mode for faster Internet data speeds. In some cases to avoid heavy data charges, you might prefer to go with 2G GSM GPRS network priority mode only.

- How to change 2G to 3G only, Edge to 4G only network mode:
- Set preferred network type or Switch Change 2G to 3G 4G LTE only mode in Android Phone:
- To Change 2G to 3G to 4G LTE only network mode in Android Phone via USSD code, take the following steps:
- How to change 3G to 4G on android phones within Qualcomm Chipset Processor:
- Switch between 2G / 3G / 4G LTE on android mobile phones with Mediatek Chipset Processor
- How to Dual LTE mode or Enable dual SIM Card 4G
If you have 4G phone below methods will help you to switch between different network modes or force 3G / 4G only mode on Android. But if you have a 3G smartphone and want to use 4G LTE SIM card on the 3G phone you can check the 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.
How to change 2G to 3G only, Edge to 4G only network mode:
To change from 2G to 3G only, Edge to 3G only, 2G to 4G LTE only or Edge to 4G simply go to Android Settings >> Wireless & Networks >> Mobile Networks >> Select The SIM card >> Network Mode. As shown in the image below from Network Mode you can select the network that you want to choose. All the possible option will appear. If 4G LTE is not showing then that mean your phone is not compatible for 4G SIM or 4G signals so is with the 3G.
The android operating system offers a variety of options to choose the best Preferred network according to your comfort. We found that in some Dual SIM smartphone users face difficulty in selecting their desired preferred network mode. Below are two solutions, with which you can Toggle 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, JIO, Idea, BSNL unlimited plan (3G without usage restriction), and many other operators have also launched low price data plans, but mostly with Data cap/speed restriction. The below image illustrate how to convert 3G 4G only network mode in an android phone.
Set preferred network type or Switch Change 2G to 3G 4G LTE only mode in Android Phone:
- First Go to Settings
- Select Wireless and Networks and TAP on MORE
- Scroll Down and Touch on Mobile Network
- Tap on Dual SIM / SIM Settings
- Select “Network Mode” or “Preferred network Type ”
- Some option Will Pop in the Screen
- WCDMA (Means 3G) , GSM (2G ) , LTE (4G)
- Choose the best Suited Option for according to your preferences
While doing the Switching between networks make sure your SIM card is compatible with the Network type you chose. WCDMA means 3G or 3.5G, GSM Means 2G (GPRS or EDGE) while LTE or VOLTE means 4G network. If 3G or 4G LTE option is not showing, it means your phone is not compatible with 3G/4G sim cards (Airtel, BSNL, Idea, Vodafone, Tata Docomo, Reliance JIO)respectively.
*NOTE: 1# Always choose 4G for higher Internet Speeds. 2# If you have chosen 4G LTE only it means that SIM will only work if 4G signals are available so always choose preferred instead on the ONLY mode so that if the 4G signal is low the phone can run on 3G signals as a backup. 3# There could little change in the of Settings option depending on different android versions.
You can also select a 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 the 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:
If your mobile phone is not showing the required Network or Preferred 4G / 2G / 3G Mode, you can have more options in Advance Internet Settings method to force specific network mode.
To Change 2G to 3G to 4G LTE only network mode in Android Phone via USSD code, take the following steps:
- Dial *#*#4636#*#* OR ##626* OR ##786# (3g to 4g code) in your phone (android network setting code)
- Select Phone Information
- If you have Dual SIM Select the Slot (SIM) you want to change settings for
- Scroll Down and select the Option Under “Set preferred network type”
- From here Select the Network Mode you wish to use (CDMA / GSM / GSM auto (PRL) / LTE / WCDMA)
How to change 3G to 4G on android phones within Qualcomm Chipset Processor:
- For open Engineering mode in Qualcomm chipset processor phone download and install “Shortcut Master Lite app”.
- Open it and click on Menu.
- Search for “Service Menu” Or “Engineering Mode” and select it.
- Now you can change the preferred network.
- OR Dial *#2263# then Select Menu and Click Back again then Select Menu.
- Now go to Key Input and Enter “0000”, Select UE Setting from Popup.
- Select the desired band by going: Configure Protocol>NAS>Network Control>Band Selection>LTE Band>
Switch between 2G / 3G / 4G LTE on android mobile phones with Mediatek Chipset Processor
If your device is used mediatek chipset processor then follow below steps to use 4g sim in 3g android mobile phones.
-
- Download and install Mtk Engineering Mode app from play store.
- Open it and click on “Mtk Settings”.
- Under Telephony scroll down , to “Network selecting/Preferred Network” Option.
- Now select the desired network from the list.
These above two methods are good for those who want to use particular Frequency BAND like 2300MHz band 40 provides faster speed than the 1800Mhz band 3 and 850 Mhz Band 5. If you have inserted 4G sim card on a 3G phone
The above Preferred network Settings should work in Allview, Amoi, Reliance JIO, LYF, Archos, AT&T, BenQ, Bird, BLU, Casio, Celkon, Dell, Ericsson, Fujitsu, Siemens, Gigabyte, Haier, HTC, i-mate, Icemobile, iNQ, HP, BlackBerry, Bosch, Cat, OBI, LETV, Elephone, Pepsi, iBerry Auxus, Acer, Alcatel, MChea, Emporia, Eten, Garmin-Asus, Gionee, T-Mobile, Telit, Toshiba, Vertu, vivo, Vodafone, WND, Xiaomi, Yezz, YU yureka ,Chinese phones Nokia, Huawei, i-mobile, Innostream, Jolla, Kyocera, Lenovo, Maxon, Myphone, BQ, Star mobile, Cherry Mobile, TCL, THL, Meizu, Microsoft, Mitsubishi, Motorola, NEC, NIU, Nvidia, OnePlus, Orange, Panasonic, Parla, Plum, Prestigio, Sagem, Sendo, Posh, Qtek, Samsung, Sewon, Siemens, Sony, Spice, Tel.Me., Thuraya, Unnecto, verykool, VK, Mobile, Wiko, XCute, XOLO, Yota, ZTE, Alcatel , Sharp, Sonim, Sony Ericsson,Karbonn, Lava, LG, Maxwest, Micromax, Mitac, Modu, MWg, Neonode, Nokia, O2, Oppo, Palm, Pantech, Philips, Amazon, Apple, Asus, Benefon, BenQ-Siemens, and other android mobile phones.
How to Dual LTE mode or Enable dual SIM Card 4G
- First go to the Settings
- Tap on Network and Internet
- Choose SIM Cards
- On this Screen you will Find Toggle to enable Dual Cards 4G to enable 4G on both the cards
co
We also found that sometimes, when you insert Single/One SIM card in mobile phone 4G LTE/VOLTE works perfectly. But if you insert 2 SIM cards such as (one JIO sim and another SIM of 3G BSNL, Idea, Airtel, Vodafone) the 4G LTE Cellular internet data connectivity on the first sim stop working. This problem occurs due to the dual SIM card, so to fix this issue you need to enable DUAL LTE mode so that you can enjoy 4G / 3G on both the sim cards. Note: not all mobile phones support DUAL SIM 4G functionality.

How can I convert my sony Xperia C DUAL sim into 4G enable phone?
It is not possible, as it is not an Software upgrade but a hardware one.
Intex Aqua Young update
My HTC 626G+ is nit actually 4G enabled but 4G LTE option is shown by USSD code method.Will it enable 4G on my phone or what?
No. as it doesn't have the required hardware for 4g lte.
The menu is not enabled on samsung models. On Huawei the option is also disabled.
You can go with the 3 methods, they should work.
I didn't get the tower I seems emergency calls only what can I do and I search in my settings for 4G it seems Enhanced 4G LTE Mode in my karbonn titanium s204
Sir I am using gionee m2 8gb model in engineering mode it showing 4g/LTE option but if I select it its automatically going back to WCDMA mode unable to change band to LTE/4G using plz help me in this regard
You can try App install Method, mentioned in the post. That will allow you to switch to only one network.
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
The reason is because the phone doesn't have 4G LTE Hardware.
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.
I have tried both WCDMA And LTE but it is not showing network bars What can i do
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)
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.
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.
That setting is set default by the OEM (Samsung), so it cannot be altered without software updates.
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
Only the SM-N7505 model will support 4G sim. The SM-N750 is not 4G SIM compatible.
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 failed.is there any way to use 4G in my phone?
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.
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?
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
Hi, 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.
Thanks Bhai for your response ! Appreciated ! rgds

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.
