[offtopic]You also could consider better title for your topic.[/offtopic]
About your problem, there should be nothing special to use internet with 3G.
Like "Saunalahti" users maybe you should tick "roaming" on in the settings menu.
plz check and reply
i have installed aurora 2.10 and also with new kernel test 2.10.
i have always two problam
one problam with 3g sim
but i couldn't understand yet why my 3g sim is not connecting with internet
i have already checked all options.
Second problam in 2g sim
It does not give service provier name "no service" on status bar.
signal bar colour always white when i connect wifi then signal bar colour is changed into the gray colour.but my main issue is 3g sim which not running internet and rebooting again and again while setting.

the best thing for you to do right now is to first check the sim on any other handset . it would just take few minutes . i am saying this because your problem is pretty weird and i think problem is without your sim . have u tried any other rom ?
didn't work yet
yes i have already checked official it's also show same problem,and
Sim is working also in usb stick.
Can you explain about apns setting?
Another hint is the APN settings. I recall I have 1 SIM which is only data and can be used in 3G USB provided by carrier. But when I put this "data-sim" into my U8800, it doesn't work, tho it recogonizes the carrier name but not able to connect to the internet at all.
It turns out I have to rename the APN to another one if you use a 3rd party 3G internet device. Hope this helps...

[Q] 4 G LTE and 3G not working on Yureka

hi,
i bought a yureka, everything is great. its just that i'm unable to use 3G or LTE on my device.
it always shows edge. on my device. and runs 2G
in mobile networks preferred network type is LTE. and i have LTE service in my area.
on phone info *#*#4636#*#* By default the preferred network comes as LTE/GSM auto(PRL) and network type shows EDGE.
i have tried changing the preferred network to WCDMA preferred, then radio on/off, still network type shows as EDGE.
i have unlocked the boot loader and then flashed the modem (NONHLOS.bin) from Rohan A joshi thread in XDA yu yureka.
still im unable to use 3G or LTE.
the SIM is perfectly fine, if i put the SIM in some other phone like iphone, everything works fine.
can someone please help me i will be thankful.

no idea, im also still waiting for any reply
Partial solution found.... On LTE sim slot i. e. Sim no. 1 using *#4636#*#* and then select wcdma will change the network to 3g.
But 2nd sim the wcdma option not activate.
Same problem for me too
I'm also facing the same problem. Selecting WCDMA only option is not working. It always comes back to GSM only mode. End result no 3G and hence no internet. Only whatsapp is working. Should I ask for replacement. 10 days is not over for me yet..
Finally 3G actually work on YUREKA
Finally after lots of hit and trials I got solution.
Two things you need to do.
First
a.select default type as WCDMA only
b. enter *#*#4636#*#* from keypad.
c. Go to Phone Information and turn off radio.
d. Now select WCDMA only and click on turn on radio
Second
Delete ur APN settings and set the setting manually as per
your service provider. search setting on google.
Finally MY YUREKA WORKING ACTUALLY ON 3G NETWORK
Note : Preferably do all settings on SIM 1 inserted in LTE slot
WCDMA only
I did that. Fortunately this time I'm able to select WCDMA only. Device started working in 3G. Now when I go home, again 3G is gone.
Did that selecting WCDMA only again. 3G is back.
Every time I need to do this like selecting data connectivity/Wifi. I'm getting sick of this. Unfortunately 10 days period is also over
Finally 3G working..
Hey Guys,
If anyone here still facing problem with the 3G connection.
Deactivate your Mobile Data Connection.
Try going to APN setting remove the Proxy Value and Port Value then Save it.
Finally, activate your Connection.
Its working for me.
This is not a bug
check on forum

hello,
i dialed in *#*#4636#*#* and got that menu the first time i turned off radio and selected wcdma only and turned on radio then rebooted.
i dont know why but it says no network available.
so i changed it back to lte/gsm after switching off radio and then switched it back on. i got the network back still on 2g.
but now everytime i reboot it goes back to wcdma only and no network available..
how do i make lte/gsm the default network so that i dont have to keep switching networks when my phone boots up

I have had this problem too in a while. But I guess it go resolved somehow.
First there is SIM 1 which is only good enough to run 3G or LTE networks.
I tried a lot to run it.
Sometimes switching on and off the airplane mode gave me the 3G connection.
Not sure about LTE, the national capital still doesn't support LTE.:good:
Give it a try!
Guys first of all you need to know that only SIM 1 supports 4G LTE.
and both sim slots supports 3G but you need to get activate 3G Services on your number.
i am using 3G of Aircel and its working fine for me(Sim2).

I just changed to WCDMA only and 3g started working.
My issue was 3G will work for a day then changes to 2G. Then I have to remove the sim and change slot for 3G to work. Will wait and see how long this will remain 3G.
Good 2 know

Hey Anurag, Can you please post the APN details of Aircel that you have on the Yureka? I have tried that *#*#46 etc and changing SIM from SIM1 slot to SIM2 slot. No difference. Still on EDGE.
Thanks,
Kiran.
Setting as mine:
Name: Aircel
APN: aircelgprs
MCC: 405
MNC: 810
APN type: default,supl
APN protocol: IPv4
APN roaming protocol: IPv4
if still not working go to your nearest aircel service station..

Thanks Anurag. There was some issue that even though it was same setting that I had, I still could not get 3G. Anyway, I upgraded to Lollipop and the problem has been resolved. Now I can get it to work on 3G Speed itself. Same APN "aircelgprs".

I have no 3g on my phone

I have a galaxy s7 edge duos, my problem is that it does not have 3G signal. It only have 4G LTE and 2G. Where I live , the 4G signal is not that stable so am always stuck with 2G, I have tried all tricks, it didn't work. I even tried to change the band I.e *#0011# but I can't go beyond the first page. When I select 3G only, the phone signal will disappear
Is your APN and CSC set correctly? That fixed most of my problems when I flashed my carriers CSC.
I have flashed csc for my country and some other countries but the problem remain. Immediately I select 3G only option, the cellular signal will disappear but if I select LTE only or LTE/GSM, everything will be ok. The problem is that LTE is just coming up in my country. 3G is the network is very stable here. Please someone should help
On my 930w8, I can type *#2263# into the dialer and it opens up a band selection menu.
Thanks for the reply, this code does not work on my phone
Try the s6 method to unlock this feature. You can use Samsung phone info from the play store to see the procedure or Google it. Then try this code. I don't know. I thought I unlocked my phone this way, but my wife's s7 had band selection by *#2263# unlocked by default. So maybe mine did all along as well.

Problem with 4G signal @ Dutch vodafone 800, 1800, 2600 MHz

Hello,
I have the following problem: I can't get a 4G signal with my provider.
Vodafone Netherlands uses 800, 1800, 2600 MHz for 4G connection.
I have bought my telephone at flosmall . com
It should work, or do I forget something?
Can somebody explain this?
I had the same.
I tried some 4g signals apps to check my connection. This one seemed to fix it: https://play.google.com/store/apps/details?id=com.mcstealthapps3.networksignalsearch
Let me know if it worked for you!
I have trieded with the app but nothing changed.
But still on 3G...
I need to ask this.
Is your SIM card even 4G capable? If its older than 3-4 years it might not be.
I don't know anything about vodafone, but try googling, for one of my providers I actually needed to activate 4G on their website after logging in to my account.
Also. Settings -> Dual SIM & mobile networks. Is network mode set to 4G priority and Celluar data to correct SIM card if you are using dual setup.
Yes the sim card is capable with 4G (was using it on Lumia 950XL).
Have contacted Vodafone about the problem.
But the will only support devices that Vodafone Netherlands will be sell.
Have tried to flash lineage rom, but nothing change about the signal.
(stock Rom was from groschopp)
I also have a Le Pro 3 (x720) on the same network in the Netherlands and I have no issues with 4g.
I am currently using the Grossoshop-Rom (Build-number WAXCNFN5902011181S).
You can download several signal apps in the play-store to see if Band 20 is available to you, this is the one used in my region for 4g Vodafone.
I assume you set the preferred network type to 4G?
It's working now
Have called Vodafone again for some extra information about the frequency band for 4G.
But nobody could help me, there was one person that say i can give you a other simcard type maybe it will help. (I say how will it help if 4G works on a other phone with the same sim card, but let's just test it)
Afterwards the call, visited the shop for a other sim card
Doing the sim in slot 1 nothing changed, same 3G signal.
Was thinking this the last try and do the sim card in slot 2 and after 10 minutes i have LTE signal.
Trying slot 1 again but only 3G. changed back to slot 2 and solved.
Have earlier check slot 2 with me "older" sim card and only 3G was showing up.
I have noticed stock ROMs have better signals than say CM

You need to enter the APN settings for your provider's data coverage in the Mobile data section of Settings.

Are you on a custom ROM? Maybe it did something to the modem. If so, you need to return to a stock ROM and try.
The phone has all the bands it needs to work on your carrier, and my carrier as well. My SIM already had the APN settings for my carrier on it, and I connected to LTE right away on my x722. I'm on a vendor ROM, which is pretty much just stock eUI. I can't fathom why it doesn't work for you if you're still on stock. Have you tried the SIM in other phones?
I also have this problem in Romania with my LeECO Le Pro3, but with Orange 800,1800 and 2600Mhz. The only solution for this problem was to manualy search and select the 4G operator network. Although in settings/network operator it was on 4G/3G/2G(Auto) by default, my phone was stuck in H+/H/3G until i manualy search and select 4G. If you are sure your SIM is 4G and you have the corect APN you can try this but you will have to search and select for several times manualy to work. I find this solution very uncomfortable because every time you restart your phone or put it in airplain mode, you will have to repeat manual searches and register in 4G.
my x720 doesn't have the correct bands active. i activated them with qpst but only actived and running in sim2 (sim 1 actived but no gain lte signal)
ah! i'm on 20s

Hello, I have problem with 4G, with Android 8.1
When I back Android 8.1 I have 4G Signal.
---------- Post added at 09:09 PM ---------- Previous post was at 08:57 PM ----------
Hi, after I install All Android custom 8.1
I try install android 7.1 (AICP 12.1) I have LTE Signal
When I back Android 8.1 and select Only LTE, I don't have any signal (4g,3g etcc) I have chage to "Global" and I have H+ signal

weak signal strength

my mi a1 signal strength is very low.drop frequently from 4g network to 3g or even in 3g network have low strength and voice call doesn't have proper quality.i compare a1 with my other phone in the same room and the other phone doesn't have this problem for example if a1 have 10-11 asu signal in 3g network the other phone have 15 16 asu signal strength.so my questions:
1-anybody else have the same problem and if there is a solution for that
2-this kind of problems can be fix by software update or is hardware problem and something related to design and material of the phone and can't be fix by update?
My problem is Same
Same problem in my phone after december update no improvment
mine never have any network 4G or 3G issue.. it's working fine indoor an outdoor

I got a network issue too and 2nd sim doesn't stay to 2g only if 1st is selected as data. Consuming most of battery due to this. This happened after the first update. Please check of anyone else too has this :/

does anyone know if this kind of problem can be fix by software update or it's a problem with hardware or design (maybe unibody design blocking signal)of the phone?

i didn't understand what was the problem exactly but in my phone you can select one of two sim for data and the sim select for data automatically change to 4g/3g and the other sim will go to 2g only. if you have two sim active it's normal to drain battery a little more but i can't complain about the battery i think it's good overall

This changed the primary sim to 2g and for 5 min secondary sim found 2g and again it was on 3g. I have weak network for 3g 4g at my place, due to phone switching to 3g 4g I get higher battery drain. My old phone kept my secondary sim to 2g only. I think A1 has issue keeping phone to 2g only

for me working.this 4636 menu will change the sim selected for call and SMS (you can select sim one or two for call and SMS) to 2g and the other sim(data sim) will not show in menu. I select that GSM option and several hours later still on GSM.but after that don't go in cellular network-->network operators and search for network maybe that can change setting to defualt.you can check if you are still in 2g mode in 4636 menu or in setting-->about phone-->Status-->SIM status

Ok I got it , I don't use secondary sim for anything else then receiving the call. So i didn't make it default anywhere. After making it default to calls I could see the option in 4636 for secondary sim. So this solution doesn't work in my condition, I don't know why the just keep the secondary sim to 2g only . I have reported this couple of time but no changes. Hope they find this issue in Oreo update
