help needed to use 4g only Sim in 3g phone(devs help) - Android General

Hi guys recently reliance jio in india launched new 4g service with 4 GB daily free usage for 4 months and unlimited calls for free. they only provide service to 4g lte phones.I know that I will get only 3g speed but that's not a problem. Is there any tricks to use 4g sim on 3g phone. I tried dialing *#*#4636#*#* and selected lte but the menu comes back to wcdma . is it possible to do system changes to trick the phone that it's network is 4g.I use cm 12.1 rooted. If any one can help it will be awesome.

In no way you can change the frequencies if phone's modem doesn't allow you. It's not just faking the icon on status bar.

It just just unlocks available bands
If your modem does not have LTE band then its useless
It unlocks all bands which the modem supports nothing more

Idk... maybe the hardware supports it but needs some software changes ... like driver ...
My device (lenovo a3000h) apparently doesn't support 4g but there is "LTE" option in network type in "tablet information "...

I don't think that you can do that.

If the network only uses LTE bands, there's no way you can get '3G speeds' or use your SIM card in a phone that doesn't support LTE.

I tried to find what's the difference between 3g and 4g devices but couldn't find what i wanted ...
maybe both have the same hardware but 4g needs different software and stronger processor ...and they locked it in weak phones to prevent crashes...

how can i unlock my Sprint AQT80 to work on any LTE/CDMA newtork?
plz help and thanks in advanced

Probably bevause when it was released, 4G was prevalent in India.
I know, it has 3 bands of 4G, none currently used in India, so no way to use 4G in India.
should we not sue HTC India for selling a device with false pretense? When I called HTC, they said their devices are country specific. If so, why is HTC advertising it as a 4G device if it cannot be used even in India?

Thought so too, but their website clearly says 4G only available while roaming. So we'll have no ground. And the clearly mention which bands too. I don't remember where they advertised it as a 4G device too.

I have a 4g enabled Airtel sim (ported recently from vodafone) and it shows me only H or 3G.... I have switched the bands to GSM/WCDMA/.....LTEAUTO and restarted the phone also.... but speedtest.net shows 1.5mbps speed only...
Edit : I changed the band using *#*#4636#*#* and upon reboot the band returns to GSM/WCDMA/CDMA and EVDO (PRL)
Anyone know how to make it stick ??
Also, i am on locked bootloader, non rooted and 5.0.2

As far as I know, none of this will work until htc sends an update to enable 4G, like it did with the M8. It initially didn't support 4G, but an update was sent to enable it. That brought LTE under the options in network, whereas we have only 2G, 3G and CDMA. LTE should be there for LTE to work.
Also, from what I've heard via someone close, htc isn't considering the update, for them, E8 in India doesn't support 4G.

Dear friends, I have Nexus 5 but 4G doesn't works . My service provider supports 4G service at 800MHz and 1800MHz as it shown here http://www.gsmarena.com/network-bands.php3?sCountry=Morocco , but my nexus 5 d 821 does not work with 4G, I want to ask that if there is a solution like a roms or others things.
Thanks in advance.
800MHz and 1800MHz are LTE bands 20 and 3 which are supported by your device but those information are for Morocco. Do you have the same information from your carrier?

hey Mate,
i have Got the same problem just like you.
i have a white nexus 5 (D821) 32Gb version.
i can't connect to 4G network,unless i'm near the 4G tower.
sometimes the phone loses signal and switches to ''emergency calls only" mode even when i force switching to 3G by typing *#*#4636#*#*
If anyone you kno how to solve this problem or anyone else here do,could you possibly help me out with this.
i'm from méknes by the way.

hi friend, nice to meet you
i will try to give you a summary of what i reached in the end.
first thing, i discovered that the nexus 5 that i have is not a D821 but it's a D820 means it's the version especially for USA networks, and this mean that 4G of USA networks works on different bands than ours in Morocco, so after finding exactly where the problem, i began looking for a solution and i found this: http://forum.xda-developers.com/google-nexus-5/general/radio-enable-lte-band-3-nexus-5-d820-t2928561 and after application the lesson, i got the 4G connection on my phone, and it's work very well till now.
this is my story, and i think it's a little different than mine.

i'm glad you answered.
and i'm glad you figured that out and solved your problem.
my case is somewhat different from yours.
before enabling those bands,you never caught 4G signal.
but for me,i do get 4G signal and connect to it,i access internet data, surfe,and make calls,but it's only when i'm near a 4G network tower.
which means the band is already activaed,it's just a deal with the signal strength.
if you can help me,i'd really appreciate that.
i'm really confused wether to flash those drivers or do something about the radio,cuz this problem brings about another problem which is battery drain,
my battery drains faster cuz the phone keeps searching for network.
just to let you know,when i go to bootloader it says Lg nexus 5 D821 (H)

Dude,you won't believe this !!
i just removed the back cover of my nexus 5 and was freaked out to find out it was actually an american model D820
thought the fact that in fastboot mode( bootloader) it says it's a D821 (H)
and guess what ! that (H) confused me and made me doubting it to not be a global (indian) version.
i guess i need to flash Some bands to get my LTE working properly.
thoughtless it's working but only when i'm near a 4G tower !
please help me.

hey bro!
how are you doing ?
i hope you are fine[emoji4]
sorry for this long escape ( been so freaking busy with exams and preparation )
i really am confused with this device !
i thought it to be a nexus 5 model D820 because it can't catch 4G properly , then i removed the back cover and found it's A (D820) then went to regulatory information like you said found it's a (D821 )
went to fastboot mode found out it's a (D821 {H} )
i'm freaking confused.
i used an app called ''LTE Discovery'' to identify which bands my phone uses to connect to 4G when it catches it, i found band 3 and 7 !
do i still need to enable any additional bands like 7 or 20 to get 4G working properly ?
waiting to hearing from you soon !
sincerely,
Zackaria.

what concerns us is what there is within the system and not back cover, so depending on the picture attached and what you said, the version D821 should run 4G, because the bands necessary are already exists. did you tried other SIM cards ( maroc telecom, meditel, inwi ) ? what did you get ? the same problem ?

i'm using ''maroc telecom'' thought i tried other Sim cards nothing has changed.
i tried inwi. it works well !
i don't know if i still have to activate any additional bands like band 8 and 20 ?
i talked to the guy that have posted the video in youtube and said that i need to activate band 20 if it isn't activated yet.
then talked to developer ''azlun'' who first succeeded to activate band 3 and 20 and said that if band 3 is already activated , but 4G still doesn't work properly , then i need to activate band 8 and 20 which is impossible due to hardware limitations.
what i really need to know what bands are used to connect to 4G in morocco ?
i already have band 3 and 7 activated.
if i have A D821 what others do i still have to activate ?

then talked to developer ''azlun'' who first succeeded to activate band 3 and 20 and said that if band 3 is already activated , but 4G still doesn't work properly , then i need to activate band 8 and 20 which is impossible due to hardware limitations.
what i really need to know what bands are used to connect to 4G in morocco ?
i already have band 3 and 7 activated.
if i have A D821 what others do i still have to activate ?

as i know in morocco, the telecom companies use 1800 Mhz and 800Mhz for LTE connection, which means bands 3 and 20, so the global version D821 has bands 3&20 already exists,and the two of them and you don't need to enable any bands! take a look here: D821 LTE bands : 1(2100), 3(1800), 5(850), 7(2600), 8(900), 20(800).
did you do this step ? calling service client of "maroc telecom" on 888 and tell them that the 4G doesn't work on your phone, and the will activate 4G connection for you, although you have a 4G SIM, you have to call service client of maroc telecom on 888 to ask them to activate LTE connection

like i said,
my Sim card has already 4G network.
i already called them.
the problem has to do with my device.
now, you just said Nexus 5 Model D821 has band 3 and 20 enabled.
and i tell you i used an app called LTE discovery to find out which bands my phone uses to connect to 4G i found band 3 and sometimes band 7.
if it's the global version why it doesn't use band 20 ?
maybe i need to enable band 8 or 20.
imma call service client f maroc telecom tomorrow and ask them which bands they rely on.
then, imma be taking the next step.
i will really need your help bro.
and excuse my ignorance.

The 4G signal that the networks worldwide use are not the same, GSM 4G is not the same as CDMA 4G, also, some 4G devices in the past were not true 4G, they used Wimax which is not actual 4G. My point is, the 4G your network uses is probably a different signal type or its bands do not match the bands the device supports. Research the exact signal type and frequency bands that Verizon supports, then research what signal type and bands that your network supports.
Many times I've seen 4G CDMA devices used on other networks and 4G could never be made to work, they were stuck with 3G because the device did not support the 4G type their network uses.
Most devices on other networks but still have 4G can count themselves lucky.
Thanks for your reply,
I flashed this rom (CM13) ; http://forum.xda-developers.com/gal...m-cyanogenmod-13-0-nightlies-verizon-t3269675
my provider is "Djezzy" , and i think its 4g LTE.

You "think", no, don't assume anything, even if your provider uses 4G LTE, if the bands/frequencies of your network are not supported by the device's hardware then it isn't going to work. As I said the first time, you need to do the research to see what bands and frequencies Verizon uses and then do the research to see what bands/frequencies your service provider uses. I mean find the actual values of Verizon's bands/frequencies and the actual values of your networks bands/frequencies, you need to compare them to see if the use the same bands/frequencies, not just whether its 4G or LTE or not. Do you understand what I'm saying?
Also, their may be radio/modem incompatibilities, the radio modem is part of the stock firmware that remains on the device, ROMs are just the system partition and not the whole operating system, software that is under the ROM is still the software the device came with or had before you flashed a custom ROM.

You need to find out what lte bands your carrier uses. And make sure they are comptible with the sprint varients lte bands.

If what I've read is correct, Sprint Note 5s have the same hardware and radio band capability as the international version. So a hack or something should be possible. But how or what is way beyond me.

Vodafone India 4g Issue

I have honor 6X indian variant.My 4g connection works fine when I am using Reliance Jio carrier sim card.But when i switch to my vodafone simcard i am unable get 4g data speeds.I am able to view vodafone 4g network and connect to it.But when i turn on my mobile data i am only getting 2g or 3g speed.I have talked with customer care , rechecked my vodafone internet settings they all are fine.Vodafone is set as primary sim and 4g is enabled.Even my subscription plan is 4G plan i have checked.Can anyone help me to resolve this.
Update : 11/09/17
Yesterday i got update BLN-L22C675B340 , after installing there was no immediate change. but today since morning i am able to connect to 4g network all right. Don't know if it was due to carrier issue or phone software issue but its has gone away now for good.
Maybe you live in an area where Vodafone have no band of LTE that's compatible with your device
im using idea 4g. i do get 3g speed sometime when there is no 4g signal but at my home i alway have 4g i got good signal at home.

So this makes my conclusion a logical one, Vodafone doesn't provide a 4G band that's supported by your device in the area where you live!

Hide the IMEI info OP.
I use Vodafone 4g in my Honor 6x 3gb variant and its working fine...
From the screenshot you provided, we're you used to set your network manually to Vodafone 3g rather than 4g network?
