First off I've tried searching for a similar topic and couldn't find anything.
So here's my issue. I updated my SGS which I bought from a local O2 store here. Checked that is was indeed unlocked and went ahead to follow the instructions that can be seen here in the forums.
After installation, the language was set to an Eastern European locale, which conveniently was easy to change back to English.
I could not connect to any network, so did all the app installations via WiFi. It wasn't until early this morning when going to work that I noticed that I didn't have any DATA going through.
Checking on the settings, I now have the option to connect to CDMA networks, instead of the option to disable 3G (Only connect to 2G networks).
What do I do to get that option back?
Thanks in advance for your assistance.
You need to manually install your phone network details or AP (Access Point) details.
Firstly check you have any details entered.
Settings > Wireles and network > Mobile networks > Access Point Names
If you don't have any details in here then you need to find the information and put them manually in.
Other then this you can check your Network Mode the next entry below Access Point Names and select the mode you wish.
Mine is GSM/WCDMA auto.
Wish you luck with it.
That's the thing, there are APN's on there and all. It's just that the setting for 3G had now changed to CDMA. Is there a way to just flash the specific CSC and not affect the PDA & PHONE?

PDA must always be flashed. THe other two you can add if required.
WCDMA is the same thing just make the selection you want. No need to flash a different CSC. I'm using JM1 at present and it's WCDMA as it's from Europe but it doesn't effect the phones capability. It's just a name.
Thanks for the reply. So what you're saying is, even if it is saying WCDMA, it WILL connect to HSDPA? Flashing my phone now back to JM5. All other FW's I've tried just show WCDMA instead of 3G.
Eventually settled for JFF and 2G option is back. Now I have the problem of the APN's working. Off to weed through these forums again.
Different question, same problem unresolved. So my original problem is that I seem to have lost all data connectivity (apart from WiFi) after the very first FLASH. OH well. Thanks for your assistance Ancient_One.
WCDMA is not CDMA. It might be confusing a bit, but it's actually two different things. WCDMA is basically just another name for 3G.
(Well, it's a bit more complicated than that, but for the sake of simplicity, let's just leave it at that.)
Yes, WCDMA is 3G. It's not CDMA as used by Verizon and Sprint in the US (they just share some of the radio-level technology).
Thanks for clarifying the bits regarding WCDMA. My how things have changed. Anyway, I'm going back to JM5 and am hoping to get internet up and running. It is so annoying to not have everything working as they should, even after the APN's been added and all.
Much appreciated guys.
Hi all,
I'm struggling to get data connection over the 3G network, even though I've got a data plan and the settings seem to be on point.
I'm based in Dubai and I've got a Middle East tab (garbage as the firmware excludes the Android Market), so I've flashed a recent Euro firmware (JIP was the build if I recall)
When I go into network settings to choose 2G/3G/Auto, it shows me GSM and WCDMA as the choices. I'm pretty sure before the flash, it showed GSM and WCDMA. Is WCDMA the same as HSDPA?
The problem could be with the carrier, but I'm troubleshooting at the moment and this WCDMA is a bit confusing.
Any insights would be greatly appreciated. Thanks.
Have you checked your APN settings? Chances are that the Euro firmware doesn't have the APNs "pre-installed" for your carrier(s). The good news is that you can add them in manually if this is the case.
Regards,
Dave

If your display shows a 3G or H type signal, then your problem is a bad APN setting.
WCDMA is 3G and H on your display, if you have that then you're in good shape.
Search the net or the carriers website for the the correct setting, then create a new APN and data will instantly start to flow.
It was missing the apn setting. Justed typed it in manually and Im hooked up. Although i was bamboozled for a little while as the H didnt apear until i had turned off the wifi.
Thanks for all ur help guys.

Hi, My name is javier, I have bought one nexus 4 8Gb orange phone, but it is sim-unlocked so I can use my MVNO ( mobile virtual operator network) But I am unable to use 3G or WCDMA band in spain.
I Know here are some problems about MVNO and 4.3 and 4.4 and 4.4.2 Android versions, but my problem is not this one. On a Vodafone SIM Card, I am unable to get internet also on this unit. The rest of the phone works flawessly, but 3G does not. I am starting to think that GSM chip is broken. But Hey 2G Networks works well no signal lost, perfectly clear voice on dialing, and constant 20kb internet data speed. No matter is an MVNO or a real operator like Vodafone.
Searching the net, i came over this:
Nexus 4 Suffering from 3G and 4.ยท Upgrade
And for all of you that are not going to take a deep read, let me tell, that they say there is an error on 4.3 and newer Android framework and Radio Baseband version. So people get unconsistent 3G connection. Well mine is really consistent. No conection at all never. So I think this is not my problem, although I have tried a bunch of roms even all google ones, all basebands and a couple of sims from diferent company.
Anyway, a quick fix is quoted here: Quick 3G Fix But I do not understand what is this or what I am supposed to do with that. Can someone help me with this?
And, after that, I start to look at something more, like Sim Unlocking is snot well done and 3g Band is still locked. Havent tried it with Orange sim as I do not have any. Is there any secret menu where network locks are shown?
And moreover, How can I trace what is happening to my chip? If someone has made hybrid basebands to unlock 4G, there has to be a way to track what is happening to radio basebands while they are working...and perhaps, I can gather some good info to work with...
One more thing on *#*#4636#*#* menu, I can force WCDMA or GSM or the rest options, If I use Force WCDMA, I get signal lost for ever, If only GSM or WCDMA Preferred, it has signal but only gprs internet conection. This is with ONO (MVNO). But with Vodafone, I get HSPA Conection but no internet at all.
Really annoyed with this, hope someone is able to help me with this.
Thanks to all in advance.
Nobody? well i will try to find out myself.
Anyway I have started to know something about android tracking with logcat, and would like to know if there is any way to check all the traces of the modem to check if the chip is faulty or is a driver issue and i have to learn to modify it myself. Thanks.
All -
I recently purchased a used RAZR M for my wife. She enjoyed borrowing my work phone, so I figured she'd like this. Except I can't get the damn thing to switch to an LTE band. I've swapped sim cards and thrown mine in, same thing. No 4G. I've compared it to my work phone and the settings *look* to be correct. In the same room, my work phone gets LTE, so I know it's not a signal strength issue where I am.
I don't know the history of the phone itself. Would this be the result of it being switched to GSM use? Is this a radio problem? Is this a firmware problem? Is this a PEBKAC issue?
Keep in mind, this is on stock. I'm not too keen on being stuck on stock, I don't have a lot of choices with it being locked and on KitKat right now.
I'd appreciate any help/insight that y'all can offer.
Still looking for some insight. For what it's worth, the phone is being used on VZW now, it just can't / won't get LTE.
Check with your provider that you are using the correct APN for LTE. I know my provider has a specific APN for LTE and another that will only connect using 3G. It took multiple calls to their broadband tech support before someone pointed me to the correct APN config.
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
