[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...
Hi everyone !
Lately I went to a place were 3G/4G was not reachable and it is there that i noticed that my brand new Moto X play couldn't get any connection in 2G (GSM) mode even if the place was fully covered with 2G/EDGE (GSM)...
In 3G/4G there is no problem only on 2G (GSM).
I tried in the settings to put 2G (GSM) only and I can not get any signal even now that i'm back home ....
I tried a factory reset from the recovery it did not work :crying: Do you have an idea on how to solve that problem ?
I also tried to use the sim card with another phone in 2G (GSM) and there it works fine with maximal signal ....
Thanks ! :laugh:
Hallo,
I did a test and I got the same "problem".
Turned 4G into 3G...no problem.Still connected..
Turned 3G into 2G....no signal.
Turned 4G into 2G..no signal.
You can try to switch networktype in *#*#4636#*#*
No time for me now....I will try it later on the day.

I just tried it and turned the networktype to "GSM only" then i got no signal just like before. If i try to use another type like CDMA/GSM it connects to 3G and works but still the problem with the GSM/2G....
Hi guys. I'm not experiencing this problem on my XT1562. switching between bands is fine and working on my device. What kernels are you guys using?
I'm using the stock kernel, I just flashed the OTA (6.0.1) from the stock recovery
Same Problem, more information
For my Moto Play X I have a very similar problem:
4G works, but 3G and 2G do not. If I'm connected to a 4G network, I see that there is reception and can use all data transfer functions. But when I want to do a call, I get a timeout. When I'm in a place where there is no 4G network available, I see that I don't have signal - but the network is shown in the list of available networks for manual selection.
As I have a dual SIM variant (stock ROM, not a custom modification or "upgrade") my second SIM does work like a charm. I tried now and swapped the SIMs - and it seems that just the SIM1 slot is having those problems. The same SIM also works perfectly in the second SIM slot.
I also tries to reset just the network settings (an option provided by the stock ROM) but this didn't change anything.
Next step I'm currently working on is doing a factory reset - will take a while until backup and restore will enable me to see the real result. I'll keep you up to date....
UPDATE: factory reset didn't change anything - will send phone to repair now. :,-(
Hi,
did anyone using Umi Super have any problems with using 4G at 800MHz? Im on giffgaff and even though Umi Super is supposed to work at 4G under 800MHz (thats what the specification states) i cant manage to make it work. I have perfect 4G coverage, 4G sim, 4G tariff, even gave my sim to a friend with S7 edge and it worked on his phone. Maybe new update will fix that? I tried with different sim from different operator (LYCA) and it works but 4G in LYCA is at 2100MHz so I didnt really check the 800. I tried everything and still nothing. Did anyone have similar problem?
I actually bought 2 phones of the same model so I decided to check if 4G worked on the other one and as I put the sim card in I just remembered something and realized same thing happened with my phone. When I put the SIM card in for the first time it DID automatically go to 4G, ok, when I looked for available networks it found O2 4G, granted BUT!!! when i got to "preferred network type" there is only 3G to pick, and THE MOMENT I PICK IT there is not possible to go back. Every network I find from that moment is only 2G or 3G. Now i reckon that a software problem right? See attachments
It is a software bug and I think I sort it out after flashing the phone. For now I sorted out the problem using Networks app by Philipp Mangalov and switching network to LTE/GSM auto
Well it seems the data part of the UMI SUPER is not so super, is it? I face a similar problem but worse. The 4G band of 800 doesn't work(despite being advertized by UMI as supported) but luckily the band of 2100 works without any issues. The problem comes when I'm out of 2100 band coverage and phone must switch to 3G - then I lose all data connectivity completely. So basically whenever I'm out of 4G 2100 coverage(which is often) I am without any connectivity! Anyone facing the same? Solution?

I only have 3G and the phone shows that I have internet, but when I try to actually use the data it just says no connection on apps.

I don't have this issue at all. My UMi Super connects perfectly to my 4g network under 800MHz without an issue here in Uganda. You can install the MTK Engineering app from the play store and check the band compatibility on ur device and you can also set the mode using the same app under android settings.
You could also try updating to the latest OTA which is 20160810 or the one before it by downloading the files from forum post here and saving them to ur phone and updating manually if you don't have the current OTA

GravityBox is a perfect solution for this problem. You can set up an icon in notification bar allowing You to toggle between 2G/3G/4G

same problem
This is indeed a software issue, one I have come accross many times - using an app to toggle between the service types is the best workaround!
There are many apps that work to resolve this, some great ones have already been mentioned.

4g Umi Super on Giff Gaff
You need Giff Gaff settings in access point name. If you try and use O2 4g it doesn't work even though Giff Gaff uses O2 network. Settings are really easy to input but MUST be Giff Gaff not O2.

All that's needed is GiffGaff settings inputing manually. Very easy to do. O2 settings that the phone recognises when a GiffGaff sim is used WILL NOT WORK. The Network is O2 but the APN settings for GiffGaff are totally different.
All you guys that think you know what you're doing obviously don't.
No need to Root or use GravityBox or any other App.

Well said. I just shake my head in despair when I see how totally clueless people try to be teachers and Internet gurus with very limited knowledge about the task at hand. These comments should come with warning stickers.
For those who want to be able to switch between 3G/4G and LTE only, use this nifty little APK that I've attached below. It will allow you to enter engineer mode without using the dial code.
Hi
This is a bug implemented in Android 7.0.
I had the same.
1 Just force in your parameters 2G/3G networks
2 wait for network authentification (no more excalamtion mark)
3 go back to 4G
Every thing will be OK to next switch off or plane mode.
Rgds,
LTE band 7 (2600) not working
I recently received my new Umi Super and updated to the last firmware V7.01_20170413, everything works fine except for the 4G. I live in an area where band 7 (2600) is available but the phone can't connect to it. Of course, my preferred network type is set to 4G/3G/2G (auto).
I read a lot about the issue on the internet but I can't find a solution.
I checked the BandMode on the phone by dialing *#*#3646633#*#*, band 7 is included and checked. However, when I tried to remove the other LTE bands and keep only band 7, I got a message explaining that the list can't be empty ("Failed. The band is changed from not null to null, it is illegal"), though the list was not completely empty because band 7 was still selected.
Also, I tried to change the radio band by dialing *#*#4636#*#*, but process com.android.phone stopped working when I pressed "select radio band", even after I cleared cache in phone and sim apps.
Can anyone tell me how to fix the problem and get connected to 4G.
BTW, Network by Philipp Mangelow is not available anymore. Switching between 3G/2G and 4G/3G/2G settings doesn't fix the issue. I tried the giffgaff settings, but the APN gets deleted as soon as I try to save it.
Thanks

You may try to force 3G and then try to force 4G
You may try to user another IMEI number from a UMI device with 2600 support (of course backup/write down the original one before just in case)
http://www.ucc.co.ug/data/imei/2
After the update to Nougat 7.x how long does it take to do a full recharge?
Do you still have fast charge feature (< 1 hour) or do you lost it like all users reported so far?
What about your GPS? Do you have a fast fix after cleaning history and is it reliable (not losing signal often?).

Is it safe to change the IMEI number? and where can I find another number for a UMI device?
GPS is working fine, it fixes pretty fast, but I'm not sure about interruption in the signal because I haven't used it enough yet
Hi All,
I bought this LG G6 (G600K) from HK a month ago. It was working perfectly until few days ago when the LTE stopped working. In the notification bar I can see LTE, but there is no data going through. E.g.: messenger shows "Connecting...". Basically no 4G internet any more. So I did my research and these are my findings:
If there is no LTE coverage, the phone switches to 3g and it works - so the problem is only with LTE, but LTE is everywhere nowdays
In this Korea Telecom ROM there is no way to configure to only use 3g (CDMA only), not even in hidden menu - this could be a remedy, but would not solve the issue
Wifi also works
I did Factory Reset twice (also Network settings reset), did not help
I waited for an update from KT, maybe contains a fix, but did not help
I went to my operator (TELENOR Hungary), and they have checked my subscription, and they said everything is ok, but they can see that my phone does not connect to the LTE system.
I tried my SIM in an other phone, and LTE works perfectly
So based on these facts, I can't think of other than the phone has a hardware issue. Do you have any idea how can I investigate further?
Thanks for any suggestion.

Have you made sure data roaming is turned on as you have Korean model, I had to enable data roaming to get mobile data as the device thinks that's exactly what it's doing.

Unfortunately it is grayed out. But 3g works and 4g worked before. I have not changed any settings, just went away.

Did you fix the problem yet?? I also have same situation like you.........
Hi, sorry to hear. I could not solve yet. I went to the 3rd line support of the operator, but they say everything is fine from their side. So I'm waiting for a custom ROM, or I will change my operator. If you can, send back your phone.

Well i just found temporary fix for grayed out data roaming..this method worked to me
download quickshortcutmaker from playstore open app and switch to normal search find roaming click on roaming - global roaming - create... you can enable data roaming from there..
And for manual network switch LTE /3G : quickshortcutmaker - normal view - network -networksettings global
Hope that helps
Sorry for my bad English..
Wow, thanks. This is working as a remedy. You are the hero of the day
Found the solution !

Hi,
I am new to this forum so welcome everyone!
I am struggling a little with my A5 from 2015. The problem is that I was not using it for two years and now pulled out from the box. All works like a charm except 3G/LTE. What I did so far:
Installed latest ROM from updato
Checked SIM card in other phone - LTE worked fine
Checked another working SIM in A5 - again no LTE
Restored factory defaults 3 times
Funny thing that I have once seen 3G connection - well at least the icon for few seconds. Also when I bought it in 2016 it was loosing network when I was in a tunnel or underground parking - so I sent it to Samsung at that time and they said all is working as expected.. i then switched to other phone.
Looks pretty much as a hardware issue to me but before I will take it to service I thought someone could have some ideas.
Also if this is hardware shall I replace the modem or antenna or both?
Thanks, Simon
If it's just the 4G/3G icon, set up an APN.
If band locking or selection is applied, set it back to the defaults.
Run a manual network search, and check the status in *#0011#. If it looks normal, it's probably not hardware.
Hi @Bryan48765, APN is fine as I tested the SIM card with same APN on other phone and all is fine - LTE/3G is there. Neither band locking nor selection is applied. I did a search for network providers and it works correctly but still no 4G/3G.
I will check the network status using a code in few hours when I have access to the phone.
