Hi everyone, I'm new in the forum although been following it quite some time.
I have a problem with my i9505. After a trip to Korea my phone hasn't been able to get 3g connection at all in China Unicom network before the trip there was no problems. (I wasn't able to get network in Korea at all btw). Now connection is always with EDGE and GSM only.
Anyways the firmware I have been using is the new (3g connection with this firmware worked fine before the trip)
United Kingdom BTU (September 2013)
PDA: I9505XXUDMH8
CSC: I9505OXXDMHA
Version 4.2.2
After the problem occurred I have done factory reset and cleared cache. Also tried the new german BTU PDA: I9505XXUDMH5, CSC: I9505OXADMH5 Version 4.2.2
Also tried different modems: ZCUCMH1, XXUDMH8 and now it is XUBMGA - none of these work. I can select all LTE/wcdma/gsm and wcdma only, gsm only etc settings from the phone but only gsm or wcdma/gsm works. Other modes don't even find any networks (in Korea it didn't find any networks with any mode)
Factory reset and clear cache was done after every flash.*#0011# shows only GSM 1800 available so for some reason it seems that the phone thinks it is just a gsm phone or does it get it from the network?
Imei code shows up normally in the "about phone" menu and I also called China Unicom operator and they said that they don't even block any imeis so that shouldn't be the problem. Internet also works so the apn settings are ok, just that it is on edge only and doesn't even try to get to 3g.
I also tried the simcard with my friends i9505 and it got working connection with H+ immediately. I tried her working card on my phone and it was still only in gsm/edge mode. Her phone had xxubmga/xxbmg3 software inside so I tried the same modem with no luck.
One thing is that I can't downgrade the phone anymore since I installed the SELinux forced UK stock firmware. Also knox warranty is 0x1 since I cfrooted the phone at one point when I had gps problems. Still even after that the phone has worked normally with the said uk stock firmware for a long time. It seems that the korea network messed the phone up somehow?
Anyways, any tips about how to fix the problems would be greatly appreciated.

Just a shot in the dark, try *#*#4636#*#*
Under Phone Information > Preferred Network, Make sure you have the proper network selected. I had a similar issue connecting to LTE, it kept defaulting to WCDMA.

The code did't work but I got to that menu via ShowService Mode app. Chose wcdma all which also set the default network in settings to wcdma only.
Anyways no luck I checked with *#0011# and it keeps jumping between three screen No service, No sib19 or sib19 received. At one point it showed hdsp0, etc but I didn't get the chance to capture that screen. Attached are the files.
Just noticed in the service menu that the NAS information - MM reject information list says "Type 1, Cause 15 460-01, UMTS"
I guess this means that the phone is not allowed in 3g network? Operator problem, phone problems or sim problem?
I'd think it is not sim problem since it works in another phone but could the operator still be blocking or not recognizing the phone as umts device? Should call operator? Though they said they don't use blacklist at least or could the korean network had ruined some phone's own network capability database somehow?
Edit: also noticed in service mode that there is plmnsearch going on so it is trying to find suitable basestation to connect but I guess it can't find one. It gives NoCellAvailable(5) error. Crappy modem? although as said previously it used to work. I'm also in Shanghai city center where my friends' phones work just fine - and mine used to.

You need to contact your provider and see if your account is setup for 3G, otherwise it will not access that network.

I called the operator and they "refreshed" my 3g settings. Also my sim worked with my friends phone as H+ so it should be activated. Can operator choose the device to attach to 3g network by phone/imei instead of sim ?
It's supposed to be by IMEI.
Sent from my GT-I9505G using xda app-developers app
anyone any idea? is it because of the imei number?
hey guys, could anyone resolve this problem?
happens to me since I got my s4 after performing root and debradign

--------------------
I have the same problem. An internationally unlocked Samsung S4 I9505 (LTE) lost its 3G connectivity during a visit in South Korea. The strange thing is that there was connectivity during the first two days of the visit and only then it lost connectivity (there were no reception bars and an icon similar to 'no parking' appeared. Also - searching for service provides did not yield any provide). Only after landing few days later in Taiwan, reception was restored. But, it seems that from then on, the telephone operates only on GSM. Setting it to 'WCDMA only' results in the same 'no parking' icon and no data.
Will greatly appreciate any advice that will help me restore the WCDMA operation.
Same problem after visiting Korea. Have you find a solution?

I experienced the same problem and it also started at Korea (a strange co-incidence). It lost all network connections in Korea for 2 days and when I continued my trip and flew to Taiwan, the connection restored (without me doing anything). But a few weeks later I did note that everything is very slow and I found that the phone operates only as GSM (I was not aware to this because it was set to select automatically between LTE/WCDMA/GSM). Since then, it seems to operate only on GSM (if i set to 'WCDMA only' - it will not connect and a grey no- connection icon appears (similar to "no parking" street sign). I Did try 'almost everything'. I rooted, installed lolipop and back to Kit Kat (this morning). To my surprise, i had a few hours of normal operation (the letter H above the data icons as opposed to E when it operates on GSM). but after a couple of hours - "no parking" sign again and it will not work when set to 'WCDMA only' (and will operate when set to 'GSM only' but of course very slow data transfer). Very frustrating! Have anyone find a solution??
Huro
I'm suffering from the SAME problem, only on Brazillian network operator VIVO.

I just bought a galaxy tab that comes from france (euro version) AND I'm having trouble getting the phone to work. But i noticed a few weird things :
-the firmware is original but rooted . Its 1000XXJK5 and Froyo BVJJ2.
-i have the phone application but i get a message that i cannot use my sim card to make calls
-sms work . I can send and receive.
-data works with no problem. Even weirder,i get 3g speeds running on Rogers even though i thought europe 3g band was different. I even used the code *#2263# and changed the data mode for 850 only. I still get data connection.
Am.i missing something? or could it blocked by rogers?
any help would be appreciated
thanks
i own a samsung galaxy s2 ordered from uk,
everything working fine except for this serious issue that i have been trying to resolve till now.
i have a monthly internet subscription from my carrier and it always been working fine on my iphone ( i mean here connecting through the 3g network ). but in the S2 .. i have to use Edge to be able to access the internet ( the mobile network mode must be set to GSM only ). whenever i switch the network mode to GSM\WCDMA auto , the 3g icon appears but when it tries to connect to internet, the phone automatically switch to Flight mode and i loose the network signal. and this happens all the time. till now i am only able to connect to the internet by switching the mobile network mode to GSM only which only uses Edge network .
i have tried every possible thing to resolve this issue but nothing worked for me. please help
What country are you in? What carrier are you on? What bands do they use?
location location location.
Where are you from?
And what frequency does operators in your region operate.
just curious, have you tried hard/factory reset?
i am from saudi arabia and i am using Mobily network.
mobily is using HSDPA network as well as Edge network.
i did a software reset and still the same issue.
phone information:
Baseband version I9100XXKDH
Kernel version 2.6.35.7--I9100XWKDD-CL161513
Build Number GINGERBREAD.XWKDD
crazy idea - is there any blocking going on in SA or with that carrier? Have you used another not carrier supplied smartphone successfully on that network?
I have been always using their 3g network on my iphone. And still there network only on edge connection on the s2. What i have noticed is that the saved apn sometimes shows up and sometimes disappears

Hi, very similar issue here.
For this four days since I have got my GS2 everything was just fine. The data connection and 3G speed was great. Yesterday, all of the sudden all got crappy. Could not display any web pages. It starting to display page but after few seconds pop-up window appear which say "Data connectivity problem. The server failed to communicate. Try again later"
Interesting that my gmail, market, xda app working fine as normal.
I'm in Ireland on O2 now.
Baseband version I9100XXKDH
Kernel version 2.6.35.7--I9100XWKDD-CL161513
Build Number GINGERBREAD.XWKDD
Can someone help to solve the problem, please. Is it possible that something with the hardware is wrong? Broken?
I'll perform the factory reset and will let you know.
i just managed to flash my device with the latest EXE1 dated May 3.
and i am still facing the exact same problem.

I have same issue, and for Ihrrob, your other application are working fine because what i noticed on my mobile that 3G & 2G connection is there but not permenant that's why WIFI hotspot always disconnect and VOIP applications are not working.

You are right the 3G/2G connection is there but not permanent.
If I press the Internet icon the home page, which is 'Google' appears (sometimes) immediately. I think this is because the page is very light. If I try to open a regular page it loads 1/3 of the content or nothing.
i just hope it is a software bug not a hardware problem
Type on the dialpad *#*#4636#*#* and force the phone to HSDPA only on the dropdown menu. This is a hidden menu on the phone.
Isn't this carrier related?

I'm on Mobily network in Riyadh, and 2G/3G is working fine for me. I stay on 2G most of the time to save battery, but have tested 3G and got around 3mbps.
I have the same Baseband, Kernel and Build number (rooted)
Are you using "Market Enabeler"? It can change your APN settings, and you need to restore the provider setting.
just rooted my device.
still same weird issue.
issue again: simply whenever my device tries to connect to H+ , the device automatically enters flight mode and automatically disable flight mode so that the signal bars come back without H+ and when i check back the saved APN i see nothing there ( thought i was there before ). and this strange behavior disappears when i switch the mode from GSM/WCDMA auto TO GSM only .. after i do this the device connects regularly to Edge network and i can browse the net.
so basicaly for me i will be only able to use the device on Edge instead of HSDPA or 3G.
im really hoping for help from here because i don't think i will find any help outside of this expert community.
regards
try to make it on obligatory 3G (WCDMA only) and check if the problem still there ..
still same problem juffo
i have noticed that another post are poping up talking about almost the same issure.
i hope a new firmware will fix this
Hi guys. I'm having a problem with my gt-i9505. I flashed a custom rom a few weeks ago (Paranoid Android), and last week I traveled to Spain. I live in Portugal and everything works fine, but in Spain I didn't get any network or data roaming. I went to the network selection panel in settings and no network was found. I was 3 days in Spain with no data/calls, and as soon as I got back to Portugal, I got my signal again and all was fine.
Does anyone have any idea of what might be wrong?

Hi ,
I guess you checked that Mobile data was enabled also data roaming?
Did you tried different bands like GSM?
Do you have roaming in your contract in Portugal?

Yep, both mobile data and roaming were enabled.
Different bands I don't think I tried... may it have been that?
As for my contract, I called them and they say everything is ok on their side, and roaming should work fine.

Hi ,
Is strange if roaming was available ( data and calls) you should had been able to connect , one thing that does not sound ok is that you did not have any operator available , even if you do not have roaming you can still see them.
Did you ask in your rom thread?

Sent from my Samsung Galaxy S4 via XDA app.
I have a new SM-G935FD purchased in the UAE. The software version is MMB29K.G935FXXU1APD1. The phone has a "United Arab Emirates" section in the About page.
I travel a lot. I generally use a local SIM when I am in a country for some time. Right now I am in France. I am using a SIM from Bouygues Telecom but I have no 4G/LTE service at all. The phone is connecting at H+ and also at 3G, but it is not showing 4G/LTE at all.
I will be in several other European countries as well as the US soon. I specifically purchased this phone because it has all the LTE bands for the countries I spend time in. This same SIM does give me LTE connections on Bouygues when I use it in my old phone (a Motorola X 2nd Gen). I had expected this phone to just work on LTE everywhere that I typically go.
I have looked through these forums and see a thread or two about others with LTE problems. But no clear solutions.
I have tried various apps such as LTE Discovery (no luck) as well as 4G LTE Switcher - using that if I set "LTE only", I get no service at all, and then have to reboot the phone before I get service back.
Is there something I need to do to get LTE?
Thanks.
Have you put the SIM in the correct slot?

Yes, the bottom slot. The SDcard is in the top slot. The SIM is showing in the phone as "SIM1".
Strange. I have a G935FD and it works with LTE no problems. I've used it in Singapore and Indonesia, with different SIMs and all work.
In Settings - Mobile Networks - Network Mode, it's set to LTE/3G/2G?

Yes it is. I've tried changing to one of the non-LTE modes and back, but no change.
In the About device / Status / SIM Card status page, I see Mobile network type as UTMS. Shouldn't that have LTE and, if so, how do I change it?
Mine says the same, but I'm only connected to 3G at the moment, so I don't know if it's normal it not. I have a 4G card in, but I'm out of my area's 4G network range.
Edit: Actually I was connected to my wifi. Now I'm connected to my 3G and it says HSPA+ now
Edit again: Ok, so my phone is jumping between 3G and H+, which is what's changing.

Ah, mine is doing the same. I see Mobile network type jumping between UMTS and HSPA+ if I watch for a while. Obviously that field is a status field, not a setting field.
Thing is, I am in an area with full LTE coverage.
At least you seem to be confirming that this should work. Still need to figure out what the problem is.
I have the same Problem in Spain. With a Vodafone Card I dont have 4G Connection (The same card in a the Galaxy S5 of my wife works with 4G). But with a Yoigo Card I have 4G Connection. The software version is MMB29K.G935FXXU1BPH6. The phone has a "United Arab Emirates" section in the About page too. Any Idea?

Hi there,
I have encountered a strange problem. I was fiddling with the preferred network services in the *#*#4636#*#* menu. Now, no matter what setting i use, i can't do any outgoing phone calls anymore, neither can i be called by anyone. I tried to set the menu back to the original setting which didnt help.
Restarting the phone, resetting the sim-settings nothing has worked so far. Does anyone have a clue what I should try to be get my telephony service back?
I am on E-Plus / LTE in Germany.
Thanks a lot!
Try to insert the sim-card into the the second slot.

Have you tried downloading the ZTE A2017G software and installing it? Not too sure about the European model but that has saved my butt with the North American model more than a few times
The phone is stuck in "LTE only" mode. It doesn't connect to 3G or 2G networks anymore. And since my provider does not support VoLTE, there is no telephony service for me. I just found that out in a place where there is no 4G connectivity. The question is - how do I get my phone to connect with 3G and 2G networks again? I tried all preferred network settings in the service menu as well as all settings in the sim-card settings. I formatted the cache. No change. I will try your suggestions and see if that helps. I still find it weird, that I am able to set my phone to 4G only but I am unable to set it back to normal. Btw. the phone is stock and unrooted.
Thanks so far!

I re-installed the A2017G Nougat Update, but that didn't change anything. So I downgraded to B10 (6.0.1). The integrated backup process went bad, so I ended in recovery doing a factory reset. From there things started to get better again, the phone finally connected to 3G and 2G networks! So I updated to Nougat and right now I am setting up my phone again, hey but it works!
I want to warn A2017G users to mess around with the info menu *#*#4636#*#*, especially dont touch the "frequency selection" menu. It gave me two choices "United states" and "800 cellular", both seemed to be wrong for me living in Germany, but I had to choose between the two. I suppose that got me into the trouble in the first place. Stay away from that menu. I learned that the hard way.
